Life Saving Appliances Onboard Ship

December 4, 2019


Recently accidents involving lifeboats
and launching appliances have increased in number as many as 125 accidents took
place between 1989 and 2003 salting in 12 persons losing their lives many of
these accidents which took place during regular on board drills can be
attributed to lack of knowledge lack of experience and poor maintenance of the
device by the crew typical causes of accidents include improper resetting of
the lifeboat release device inadvertent operation of the release handle and
cable rod malfunction following a spate of incidents the soleus Convention was
revised and as of July 2006 annual inspections servicing and repair are to
be conducted by the manufacturers representative or a person trained and
certified by the manufacturer in this DVD program you will be shown operation
and maintenance fundamentals for various types of life-saving appliances with a
focus on accident prevention the guidelines introduced are general in
nature for a specific model or product users are strongly advised to refer to
the instruction manual provided by each manufacturer standards specifications and functions
applying zat lifeboats are strictly regulated by the sonís Convention
lifeboats covered by the 83 amendments include partially enclosed lifeboats
totally enclosed lifeboats and totally enclosed fire protected lifeboats that
are equipped with water spray systems and air supply devices most lifeboats used on modern general
merchant ships are of a totally enclosed design ie they are covered with a canopy
and have a propulsion engine as for passenger ships partially enclosed
lifeboats are the most common ships with highly flammable cargo for handling
toxic materials carry fire protected life wounds all lifeboats have both off
load and unload release functions simultaneous release of both ends is
possible following enforcement of the 1996 amendment to the LSA code all
lifeboats are provided with an interlock mechanism to prevent accidental release
before the lifeboat is waterborne totally enclosed lifeboats are usually
launched using gravity type Dartmouth’s however all bulk Carians built after
July 2006 are required to have free fall launching devices to provide you with a better
understanding of the structure and operations of various kinds of
life-saving equipment on this DVD we will deal with lifeboats life rafts rescue boats lifejackets immersion suits distress signals and
other accessories gravity type davits swing a lifeboat
outward and lure it into the water they consist mainly of a pair of frames
davit arms are lashing device boat Falls suspension blocks and both winches the lifeboat is lowered at a constant speed
using its own weight by operating either the remote-control wire inside the
lifeboat pull the remote control lever on the ship’s deck let us take the
closer look at lowering and launching operations for totally enclosed
lifeboats with gravity tight planets prepare a set of transceivers and
confirm that communication is possible also confirm that the cable for the
storage battery charge has been detached confirm attachment of the painter to the
lifeboats painter release device the painter should be connected to the bit
of the parent ship as far forward as practicable move the over lashing wire ropes if
fitted some vessels are not equipped with over lashing wire ropes over
lashing wire ropes once removed should be kept together but far enough
away to prevent entanglement with the lifeboat tangling of the rope with the
lifeboat could lead to a serious accident the auto trigger wire rope
comes off automatically when the lifeboat is swung out pull out the
safety pin to release the boat winch break pull out the
it arm stop safety pins both fore and aft and release the stop by pulling down
the handle in one continuous motion confirm that the remote control wire has
been drawn into the lifeboat then open the access hatch and get on board once
inside the lifeboat immediately fit the bottom plug open the fuel valve and the cooling sea
water valve and close the drain valve on the exhaust
pipe then confirm that all crew on board have fastened their seat belts the
operator starts the engine and pulls down on the remote control wire to swing
out the lifeboat once swing-out is complete fully pull
down the remote-control wire the lifeboat will descend at a fixed speed
using its own weight as the lifeboat approaches the water’s surface the
operator should alert the crew about impending splashdown avoid rapid swing outs or abrupt halts
during the swing out operation as this can have a dangerous impact on the boat
inching operation is also dangerous since it shakes the lifeboat life boat
swinger and lowering operation can also be conducted using the operation lever
on the deck of the parent ship there are two types of release for launching a
lifeboat one is the offload release the standard
method of launch and release and the other is the unload release which is to
be conducted in emergency situations only when the lifeboat is fully water
borne and there is no load on the release hook carry out offload release when the lifeboat is not fully water
borne and there is a load on the hook unload release shall be performed the release care system comprises a pair
of release hooks located fore and aft of the boat a release handle on the side of
the steering seat a pair of control cables a hydrostatic unit to prevent the
lifeboat from plunging due to mishandling and an interlocked cable
there are two types of hydrostatic unit a direct system that controls detected
water pressure directly through an interlocked cable and an electric type
that electrically controls the interlock lever with pressure signals to operate
the relay and the solenoid the interlock mechanism which prevents a mishandled
lifeboat from falling before it is fully water borne became mandatory for all
lifeboats under the so last 96 amendment the offload release is an operation
conducted when the lifeboat is fully water borne and there is no load on the
release hook prior to conducting this operation the following should be
confirmed no ropes or lines are entangled on the fore and aft release
hooks the lifeboat is fully water board the engine has been started and finally all crew are in their seats
with their seatbelts fastened after all this has been confirmed the operator
releases the safety lock device pulls out the release handle safety pin and
pulls the release handle to the fully open position in one continuous fraction some release gear systems do not have a
safety lock device in normal situations the interlock unit detects the water
pressure and releases the interlock when the boat is afloat so it is possible to
carry out an offload release using the release handle however in the event that
the hooks have not released it is necessary to conduct an unload release the unload release should be reserved
for emergency use only when the hooks are not released due to malfunction of
the hydrostatic unit all when seas are rough and normal offload release is not
advisable to conduct an unload release first open the cover of the interlock
device fully raise the hydrostatic interlock lever and while holding it
insert the securing pin to release the interlock then release the safety lock
device next remove the release handle safety pin and pull the release handle
to the fully open position in one continuous action some release gear systems do not have a
safety lock device release the painter and immediately get clear of the ship now let’s look at the recovery operation
at least three persons are required for this operation accidents involving
lifeboats often take place during recovery of these accidents seventy
percent are due to improper resetting of the release gear and such mastering the
proper way to reset the release gear is extremely important
properly resetting the release hook is an essential part of every recovery
operation improper resetting may lead to the lifeboat being held by only one hook
or even falling resulting in a fatal accident there are various types of release hooks
regardless of type improper resetting is indicated when the safety pin cannot be
smoothly inserted or when extra force is required to return the release handle to
the set position if you have any doubts about the resetting operation start over
and redo each step in the process to reset the release hooks begin by pulling
the release handle upward for about 30 degrees next simultaneously lift the
fore and aft hooks after ensuring that the hooks have been reset properly
insert the safety pin finally reset the safety lock device and
to make sure that it is in the locked position the safety pin cannot be
inserted unless the release handle is in its locked position the reset procedure
is the same no matter which type of release hook you are dealing with lift
up both the full and aft hooks and swing down the release hook reset levers the
release handle is automatically reset confirm that the release handle is fully
reset and insert the safety pin next insert the winch handbrake safety pin the lifeboat until it is under the boat
falls using the winch adjusts the suspension links to the proper height simultaneously connect the suspension
links to both the fore and aft hooks operate the winch using a remote
controller and begin hoisting stop hoisting the lifeboat when it is just
clear of the water and confirm that the fore and aft hooks are properly
connected also confirm that the hydrostatic interlock lever has been
moved back to the locked position resumed hoisting when the davit arm
approaches the stowed position the davit arm strikes the limit switch and the
boat winch stops automatically only after it has been confirmed that the
winch has stopped completely may the crew disembark the lifeboat place two
persons on the davit platform to oversee proper stowage when the winch stops
automatically manually hoist the davit arm confirm that the davit arm is in
contact with the platform stop and cease winding the aware of over winding do not
forget to detach the manual hoisting handle once winding has been completed immediately reset the davit arm stop and
insert the safety pin in the davit arm stop handle after removing the handbrake safety pin
lower the suspension blocks on the davit horn by releasing the handbrake if the
suspension blocks are not on the Taffet horn the boat Falls will remain under
tension and may be damaged insert the handbrake safety pin be sure
to turn the end of the safety pin install the auto trigger wire rope and
use turnbuckles to tighten it install and tighten the over lashing
wire rope the painter should be kept attached to
the painter release hook at all times you find protected lifeboats are totally
enclosed lifeboats with water spray and n supply systems and are carried on
ships such as tankers the water spray system on fire protected
like books effectively cools the surface of the boat in Berlin in order to
protect the hull surface from fire damage and the cabin from high
temperatures thereby enabling the lifeboat and the crew to evacuate to a
safe sea air if fire breaks out near the parent ship following an accident the
system protects the microbes and fruit for at least eight minutes the spray
system pumps seawater with a spray pump ejecting it from nozzles on the external
surface of the boat cooling the hull before starting the operation be sure to
close the hatches and other openings and confirm that the main engine is idling
when preparations are completed increase the RPM of the main engine and begin
spraying the air supply system protects the crew when they encounter a fire on
the seat or are in an environment filled with toxic gas in escaping from
hazardous area all lifeboat openings are closed the system provides clean air
sufficient to operate the main engine and sustain the crew for not less than
10 minutes you containers of highly compressed air
found inside the lifeboat supply air to the lifeboat via a pressure regulator during use the valves on every
compressed air container and the pressure check stop valve have to be
opened confirm that pressure for air containers
is maintained at the primary pressure gauge level indicated on the high
pressure side of the air regulator while observing the secondary pressure gage
level on the low pressure side of the air regulator adjust the pressure using
the regulators handle so that the in boat differential pressure indicator
shows a pressure slightly higher than the external air pressure check that the
air is being discharged now let’s look at the freefall lifeboat
system all bulk carriers of 500 gross tonnage and upwards built on or after
July the 1st 2006 are required to have a freefall lifeboat free for lifeboats are
placed at the ship’s turn in the event of an emergency the crew
board the lifeboat in its stowed position and then conduct a freefall
launch the launching operation can be performed from inside the light the davits unit of a freefall lifeboat
consists mainly of a slight rack add avid arm a pair of suspensions a
hydraulic cylinder and a lashing device the winch is composed of a wire drum a
hydraulic motor speed reduction gear and hydraulic brake gear prior to launch make sure that the water
surface is free of obstacles release the lashing line and confirm
that the lashing plate has been released the lashing plate will be released
automatically once the lashing line is released if the lashing plate is not released
release it manually using the attached nylon rope next check
that the battery charge cable has been detached remove the release hook safety pin and
open the rear hatch ferm that all necessary launch
preparations have been completed the crew should then board the lifeboat from
the rear hatch finally the Coxon boards the lifeboat
and closes the hatch tightly from inside after everyone is on board confirmed
that the boats drain valve has been closed all crew members should be seated
should fasten their seat belts and should grasp the handrail on the seat in
front of them do not forget to use the headrest belt if it is available the
operator should conduct a final check to confirm that all crew members have
fastened their seat belts and that they have not put on life jackets then the
operator may be seated and fasten his or her seat belt when doing so please avoid
touching the release lever the operator starts the engine removes the release
lever securing pin and closes the bypass valve pumping the release lever several
times releases the main lashing allowing the lifeboat to achieve freefall launch once the launch has been completed
immediately leaves the parent ship for a safer area never use a painter during a
free fall launch in the event the hydraulic system does not function
properly and emergency release is required confirm that the bypass valve
is open break the acrylic cover insert the emergency release handle and turn
the emergency release bolt clockwise until it comes to a stop the stopper of
the main lashing will open and the lifeboat will be launched when a
freefall is not possible due to insufficient water depth or when the
ship is in an inappropriate area from freefall it is possible to lower and
launch the lifeboat using David Holmes when launch preparations have been
completed and confirmed switch on the hydraulic power bank operate the control
lever to lower the Traverse and subsequently remove the hook
lashing lines attach the wire ropes to the suspension using the lever position the data turns
just above the boat lifting position and adjusts the fore and aft balance of the
lifeboat the crew members embark the lifeboat from the rear hatch take their
seats and fasten their seat belts each member should grasp the handrail on the
seat in front of them the operator then boards the lifeboat and closes the hatch
the operator confirms that all crew members have fastened their seat belts
and then removes the pin securing the release lever and closes the bypass
valve pumping the lever several times releases the release hook and removes
the main lashing after visually confirming that the main lashing has
been released the operator on the main ship shall use the control lever to
swing the davit arms to the proper lowering position and then lower the
lifeboat when the boat is waterborne and has
become well-balanced the operator onboard the lifeboat shall indicate to
the operator on the parent ship to stop loading the boat the operator on board
shall remove the wire ropes used to suspend the vent and attach them to the
plate providing the boat engine can now be started immediately leave the area of
the main ship switch on the hydraulic power pack on the parent ship the operator on deck uses the control
lever to swing out the data tones next lower the suspensions to a height
allowing the wire ropes for hanging the boat to be attached these steps should
be carried out under instruction from an operator onboard the lifeboat the
operator onboard the lifeboat attaches the wire ropes to the suspensions after
signaling to the operator on deck the operator on board the lifeboat should be
seated with seatbelt fastened and should stop the engine the operator on deck
confirms that the engine has been stopped and starts hoisting the boat the
movement of the Traverse should be halted prior to coming into contact with
the hinge block and the wire rope support by operating the control lever
stow the davit arm to the boat set position station and operator on the
platform stop the operation before the davit rear span and the boat come into
contact using the control lever lower the lifeboat until it is positioned on
the roller raise and lower the lifeboat several times with the control lever
thus adjusting the stowed position until it is possible to attach the main
lashing each operation should be implemented slowly and in concert with
the signals provided by the operator stationed on the platform securely
attached the main lashing to the release hook after confirming that the main
lashing is secured the crew may disembark the lifeboat via the rear
hatch the operator on deck lowers the suspensions detaches the wire ropes for
hanging the boat and attaches them to the plate provided using the control
lever move the davit arms to the stowing position although the davit arm stops
moving when it comes into contact with the arm support keep an eye on the davit
arm during this operation attach the hook lashing lines to the suspensions set the lashing line the lashing plate
is set automatically once the lashing lines are attached turn off the power
pack the sonís convention requires that full
vessels equipped with freefall lifeboats also carry rescue boats you let’s take a look at rescue boat davits
launching operations using the davit can be performed both inside the rescue boat
and on deck it is mainly composed of a post stand
davit arm a release hook hydraulic power pack and a winch carrying a freefall lifeboat rescue boat
davits can also be used as life raft davits the winch unit is composed of a
wire drum electric motor speed reduction device handbrake device and a governor
brake device lowering and launching of the lifeboat is possible by operating
the slowing remote control wire the inboard remote control wire deck remote
control wire and the hand brake device which allows the lifeboat to descend at
a fixed speed under its own weight boats automatic release work is composed
mainly of a hook a hook reset lever a release lever an automatic release wire
and an on load release wire when lowering and launching a rescue
boat begin by switching on the power pack open the accumulator valve and
confirm that the davits looing area is free of obstacles confirm that the
slowing remote control wire and the inboard remote control wire have been
drawn into the boat confirm the boat hanging wire is attached to the
release hook and that the painter is set to the painter releasing device which is
located at the bow of the rescue boat remove the lashing wire rope remove the
safety pin from the handbrake device on the winch board the crew the operator on
deck uses the hoisting switch to raise the boat free of its stand during hoisting swing-out launching and
release of the rescue boat the operator on deck shall stabilize the boat using
the painter the crew on board the rescue boat pull the slowing remote control
wire and slew the dammit to the lowering position slowing stops when the
operators hand is removed from the slowing remote control wire prior to
slowing and lowering of the rescue boat ensure that the tracing line has not
become entangled with the boat if the power supply is cut off pressure stored
in the accumulator can be used to complete the operation however if the
amount of stored pressure is insufficient slew the davit manually
with the hand pump when the crew pulls the inboard remote-control wire the
winch break is released and the boat begins to descend tact with the surface of the sea the
automatic release wire should be pulled to release the rescue boat after
starting the engine release the painter releasing device and proceed with the
rescue the operator can also lower the boat by
pulling the deck remote-control wire or lifting the brake lever on deck in the case of automatic release pull
the automatic release wire to bring it into the set position for automatic
release mode prior to making contact with the surface of the sea as long as
the hook is bearing a load it will not open once the boat is waterborne the
hook will release automatically for the sake of safety pull the release wire
after the boat is water borne if the automatic release hook does not function
after making contact with the sea pull the unload release wire and release the
hook as in the case of automatic release operations unload release is carried out
by pulling the automatic release wire into the set position for automatic
release mode pulling the unload release wire and releasing the hook insert the
safety pin and lock the winch handbrake device attach the shackle of the boat
hanging wire to the hook in the released position pull down the hook reset lever
to reset the release lever will be reset automatically in the locked position hoisting switch to raise the boat visually observe the operation until
hoisting is stopped automatically by the limit switch the operator should confirm that the
boat slowing area is free of obstacles and then slew the davit to the stowed
position set the boat on the stand and set the boats gnashing line check the
powerpack pressure gauge and if necessary
recharge it to the specified pressure level when the operation has been
completed close the accumulator valve for recovery of a rescue boat in bad
weather use the recovery strap when launching a rescue pose in bad weather
mount the recovery strap to the joint plate in advance also prepare the
hanging off pendant launched the rescue boat by following
the standard rescue boat launching procedures remember do not use the
recovery strap for launching operations when oystering the rescue boat attached
the recovery strap to the boat link heist the boat to a position where the
hanging off pendant can be set and then set the hanging off pendant slew the
davit into a position where the boat can be pulled toward the ship and have the
crew embarked on the ship lower the boat until its full weight is borne by the
hanging off pendant and remove the recovery strap set the release hook to
the boat link voice the boat until its full weight is borne by the release hook
and remove the hanging off pendant slew the Davitt
and store the boat you they are normally folded and are kept
stored in an FRP contain life rafts carried on tankers are oil proof that
flame grip that some have a structure that prevents the accumulation of static
electricity life raft accessories include canopy
light room lamp seawater battery lithium battery safety valve for chamber inflation gear c-anca retroreflecting
tape and boarding ramp these items have specific applications for specific
contingencies some are to be used at an early stage during launching and initial
drifting some are employed to maintain the crews physical strength while adrift while others are used to maintain the
life rafts performance still others are for transmitting distress signals all
life conforming with so last 96 have
instructions stickers on the surfaces of their containers one of the most
commonly used life rafts it’s the dropping type which is stowed on deck the life raft container is placed on a
cradle and is secured by a lashing wire with an automatic release device life
rafts conforming to Solace 96 are of the weak link type and the painter is
attached to the painter connecting ring an automatic wire and an operating wire
are located at the painters midpoint the operating wire is connected to the
painter inside the container some older types of life raft have a separate
automatic wire or wires and painters and do not have a weak link manual dropping
of a life raft is possible by pulling the release handle built into the cradle the automatic release device has an
automatic operating mechanism that is triggered by water pressure it cannot be
operated manually some older types of life raft feature an automatic release
device with a manual dropping handle a cradle with a weak link has one end of
the weak link connected to the cradle and the other end either to the painter
connecting ring or directly to the painter when a ship sinks tension is applied to
the weak link and the link disconnects separating the life raft from the ship in an emergency situation it is possible
to manually initiate a gravity fall of the container along the inclined cradle
in this case the operating wire is pulled and the inflation of the life
raft is triggered opening the container and allowing the life raft to inflate
automatically some units allow inflation and discharge of the life raft by
pulling the painter manually after dropping the life raft container when
the life raft is dropped manually the ship and the life raft are moored to the
painter and no tension is applied to the weak link as such it is necessary to cut
the painter after embarkation should the ship sink before the life raft can be
dropped manually hydraulic release equipment will be activated at a water
depth of between two and four meters the containers buoyancy causes the automatic
wire to be pulled inflating and discharging the life raft at the time of
inflation the painter is disconnected from the ship upon activation of the
hydraulic release equipment the weak link is broken after the life raft is
inflated the painter and one end of the week link
are directly connected to the painter connecting ring on the hydraulic release
equipment while the other end of the weak link is secured to the ship the operating wire is connected to the
painter inside the container the painter is directly connected to the painter
connecting ring on the hydraulic release equipment and the weak link connected
and the midpoint on the painter is secured to the cradle the operating wire
is connected to the automatic wire inside the container the painter is
directly connected to the painter connecting ring of the hydronic release
equipment the automatic wire is also directly but independently connected to
the cradle all of the following must be checked prior to drop launch of the
lighthouse confirm that the liferaft container is not lashed with a rope or
other bond check that there is no feet obstructing
the cradles auxiliary rail rotating pin ensure that the pacer is connected to
the hydraulic release equipment check and confirm the connection of the
weekly make sure that the safety pin is attached to the cradles release her when
boarding the life raft from the ship use a ladder or boarding ramp when climbing
the board from the water use the boarding ramp or a letter attached to
the raft it is also possible to jump from a height of not more than 4.5
meters onto the canopy pay attention to crew already in the raft do not board
with tools cutlery or other objects that could damage the life raft if the life
raft should inflate in an inverted position climb on the co2 gans cylinder
while taking hold of the writing rein on the bottom and apply your weight to turn
it over to its normal position one person can write the life raft
this operation is much easier if natural forces wind and waves are used after
boarding the raft is completed remove the knife kept outside the canopy and
cut the painter in such a way as to leave about five meters of it attached
to the life raft after separating the painter recover the sea anchor that is
tied near the external co2 cylinder to avoid being caught in the whirlpool
caused by sinking of the parent ship remove the pedals from the accessory bag
stick them out of the two openings in the boarding ramps and row the raft
according to instructions provided maintain sufficient distance from the
ship to avoid being caught in the whirlpool only now should the sea anchor
be redeployed as an auxiliary pitcher it is possible to move the life raft by
dropping the sea anchor into the water and then pulling the life raft towards
it the initial procedures after boarding
the life raft are described in the manual instructions for immediate action
and it is strongly advised that these directions are followed if the container is connected to the
life raft and is floating use a knife to sever the connection retroreflecting tape which makes a
search for both sea and air easier is attached to the surface of the lifer in addition to this Griffin signals radar reflector dye marker to be used
during daytime etc all of which can be found in the accessories panic now let’s
see how to watch a life of using the davits launching living under the dabit
launching method the container of the life raft is lifted by the David and the
davits is turned to the life raft lowering position by pulling the
automatic wire the life raft inflates and the crew embarked while the life
raft is suspended above the deck using the dabit the life raft is then lowered
splashes down and is released the biggest advantage of the davit launching
method is that it makes it possible for the crew to evacuate the parent ship
without getting wet in normal situations the life raft
container is stored on the deck cradle the davit assisted launch procedure for
a life raft is the same as that for a rescue boat lowering and launching a
possible with the operation of a winch remote control ships are often equipped with
supplementary carry and drop type life rafts when standard lifeboats on life
rafts are installed at distances from the bow or the stern of more than 100
meters automatic release devices are not required for carrying drops like life
rounds some carry and drop type life rafts are equipped with an automatic
release device but they are used in the same manner as life rafts without an
automatic release device the life raft is carried to the dropping position
where the painter is secured to the ship and the life raft is dropped when the
life raft is installed on a cradle with an automatic release device set the
painter and the automatic wire so that they do not hinder automatic flotation
it is essential that they are set according to the manual provided by the
manufacturers now let’s look at accessories my folks
and my friends the accessories Archer you see dye marker special accessories for
life bonus pockets you extinguishing special accessories for
life rounds paddles safety scissors sponges optional accessory desalinator the satellite epub is activated when it
is removed from the installed position in the parent ship and transmission
starts automatically the name and position of the vessel in distress etc
are sent to the earth stations via satellite should the ship sink the ePub
floats by itself and automatically begins transmission the Sat radio
transponder is used for search and rescue of survivors via GM DSS global
maritime distress and safety system it receives transmissions from radar units
installed on search and rescue boats aircraft etc and transmits response
signals visual signals are used as distress signals for verses the flash
and a large amount of orange colored smoke help identify the position the
vessel you self-activating smoke signals are used
either as distress signals with the parent ship or in order to indicate the
position of a lifebuoy to a person overboard they are tied to the lifebuoy
when used once thrown into the sea they self activate and continuously produce
smoke for 15 minutes or more buoyant smoke signals are designed for daylight
signaling purposes on lifeboats and life rafts and they continuously produce
smoke for 3 minutes or more the ignition is manual and the performance is almost
identical to self activating smoke signals self-igniting lights are signals
that automatically ignite when thrown into water they continuously produce
white light or flashes of two containers for at least two hours like self
activating smoke signals they are tied to a lifebuoy when used rocket parachute
signals are launched by rockets to a height of over 300 meters they descend
with a parachute while producing a red flare of about 30,000 candelas for 40
seconds or more rocket star signals are launched by rockets to a height not less
than 150 meters producing red stars of about 250 candelas for 3 seconds or more remove the
caps on the top and bottom remove the safety pin then lift the
ignition lever to launch while holding the body of the signal vertically press
the ignition lever in the rocket body with your palm hand flares indicate the
position of lifeboats and life rafts a red colored flare of about 15,000
candelas is continuously produced for at least one minute to ignite a hand flare
lift the grip and pull out the ignition cap after ignition starts hold it as far
away from your body as possible keeping it on the leeward side the floating body
of a lifebuoy is made mainly of cork those used for rapid release gear wait
for kilograms or more and those for other devices weigh approximately two
point five kilograms lines appliances are capable of launching a
line and reaching a distance of over 230 meters toward the distressed vessel a
set comprises one rocket type launcher four or more projectiles and aligned
longer than 320 meters remove the front covers on the top and
bottom remove the wire cord attached to each projectile connect the end of the
rope at the back of the case to the ship structure handrail etc remove the safety pin and pull the
trigger following the amendment to the SOLAS
convention in July 2006 all cargo vessels at 500 gross tonnage and war
shall be equipped with immersion suits in numbers sufficient for all persons on
Jordan emotion suits come in two types those with inherent insulation and those
with non inherent insulation inherent insulation type suits which exhibit high
insulating performance allow the wearer to survive for six hours in water as
cold as two degrees Celsius normal inherent insulation suits are now the
wearer to survive for one hour in water no colder than five degrees Celsius immersion suits are dry suits that cover
the whole body with the exception of the face both inherent and non inherent
insulation suits are worn over clothing and it is required that they can be
unpacked and donned without assistance within two minutes when donning an immersion suit put your
legs into the suit and then pull the suit up to cover the whole body
including the fingers finally cover your head there are both buoyant and non buoyant
immersion suits use a lifejacket in conjunction with non buoyant immersion
suits for the anti exposure suit priority is given to improved user
movability and operability as a trade-off the
materials used are less waterproof and less capable of retaining body heat it
is possible to survive for one hour in water of five degrees Celsius it is
required that life jackets can be done without assistance within one minute and
they must also meet requirements for buoyancy and strength they are designed
to resist damage and it is required that they will not be torn from the users
body even if the user jumps from height of 4.5 meters they will not injure the
user either two types of lifejacket are available rigid type and inflatable type rigid type lifejackets have a buoyant
structure after donning a rigid type lifejacket the user secures it to the
body with a cord or a buckle inflatable type lifejackets have two
independent compartments that are inflated either manually or
automatically should inflation be insufficient use the
auxiliary air supply device which can be inflated by mouth lifejacket lights come
with the lifejacket and can be turned on manually they remain lit for eight hours
or longer according to revised soleus from 2010
all lifejackets used on newly built vessels should be equipped with a buddy
line to allow survivors to link themselves together and a lifting loop bandage type lifejackets will no longer
be approved this section deals with inspection and
maintenance life-saving appliances to be carried out by the crew onboard the ship as from July 2006 annual inspections
servicing and repair of lifeboats shall be conducted by the manufacturers
representative for a person appropriately trained and certified by
the manufacturer however it is the responsibility of the
crew on board to perform maintenance and inspection of life-saving appliances on
the ship in order to ensure reliability equipment and to maintain effective
operation the crew shall carry out weekly and monthly inspections in
accordance with the instructions for maintenance and inspection provided by
manufacturers visual and operational inspections are required for the
maintenance and inspection of lifeboats external visual checks should look for
obvious damage scratches cracks deformations and other abnormalities and
confirm that devices such as the release gear are properly reset operational
inspections shall be carried out for the release gear paint a releasing device
steering system and rudder propeller and so on it is also necessary to check that
there is no water leakage from the steering gear and the stern tube you and the all wines have been wound
corrected and supplied prices for fire protected life bonus should be checked
for corrosion off or leakage from you it is not lashed with other ropes or
bonds and that the painter is connected to the connecting ring of the automatic
release device you annual maintenance is required by
regulations for life rafts – life rafts that come up for inspection during
periodical maintenance shall be inspected and maintained at a certified
servicing station in order to maintain good performance routine maintenance and
inspection is essential proper knowledge of life-saving
equipment its handling and maintenance is essential if accidents are to be
