There are three types of lifeboats used on merchant vessels:
-Open Lifeboat:
As the name suggests, the open lifeboat has no roof and is normally propelled by manual power by using hand propelled ores. Compression ignition engine may also be provided for the
propulsion purpose. However, open lifeboats are becoming obsolete now because of stringent safety
norms, but one may find them on older ship
-Closed lifeboat
Closed lifeboats are the most popular lifeboats that are used on ships, for they are enclosed
which saves the crew from sea water, strong wind and rough weather. Moreover, the water tight
integrity is higher in this type of lifeboat and it can also get upright on its own if toppled over by waves. Closed lifeboats are further classified as Partially enclosed and fully enclosed lifeboats.
-Free fall life boat
Free fall lifeboat is similar to an enclosed lifeboat but the process of launching is entirely different. They are aerodynamic in nature and thus the boat can penetrate the water without damaging the body when launched from the ship. The free fall life boat is located at the aft of the ship, which provides a maximum clear area for free fall.
Solas Regulations of lifeboat.
-Each lifeboat shall be fitted with a certificate of approval, endorse by the administration containing
atleast following items:
=Manufacture name and address
= Lifeboat Model & serial number.
= Month and year of manufacture
=No. of persons approved to carry.
-All lifeboat shall be of sufficient strength to :
-Enable them to safely launch when fully loaded with their full complement and equipment.
-Be capable of launched and towed when a ship is making headway at a speed of 5 knots in calm water
-Except for free fall, each other lifeboat to be launched by falls shall be of sufficient strength to withstand when loaded with its full complement of person and equipment and with applicable skates
or fenders in position, a lateral impact against ship side at an impact velocity of atleast 3.5m/sec and also a drop into water from a height of at least 3mt
-A lifeboat shall not carry more than 150 persons
-The size, number and the capacity of the lifeboat for a merchant vessel is decided by the type of the ship .lifeboats are provided on both side of the ship (port and starboard).
-The requirement for lifeboat of a cargo ship with 20,000 GT is that the boat must be capable of launching when the ship is heading with a speed of 5 knots.
-The ship must carry one rescue boat for rescue purpose along with other lifeboats. One lifeboat can
be designated as a rescue boat if more then one lifeboat is present onboard ship.
-The gravity davits must be hold and slide down the lifeboat even when the ship is heeled to an angle of 15 degree on either side. Ropes are used to hold the lifeboat in stowed position with cradle.
These ropes are called gripes.
The wires which lift or lower the lifeboat are known as falls and the speed of the lifeboat descent should not be more then 36m/ min which is controlled by means of centrifugal brakes
-The hoisting time for the boat launching appliance should not be less then 0.3 m/sec with the boat loaded to its full capacity.
Regulation for lifeboat engine.
-Lifeboat shall be powered by a compression ignition engine. No life boat engine can be used if the fuel used in it has a flash point of 43 degree C or less.
-The lifeboat engine can either be two stroke or four-stroke type, and can be started either by hand or by power
-The engine can be capable to operate when life boat be flooded upto waterline of crankshaft.
-Power starting can be by using accumulator batteries or hydraulic.
-In power starting, normally two independent rechargeable energy sources are provided. However any starting method should be capable of starting engines at 15 degrees C of ambient temperature
within two minutes of commencing of starting procedure.
-The engine power is transmitted to propeller through gearbox. The gearbox is capable of disengaging the engine as well as engaging in either ahead or astern direction.
-The exhaust pipe outlet is located well clear of waterline.
-Engine should be capable of operating for not less than 5 minutes after starting from cold, with lifeboat out of water Neptha or Butane spray is injected in air filter to start from cold condition
-A fully loaded lifeboat in calm water has an engine speed of 6 knots and enough fuel for 24 hours. When towing the biggest liferaft it makes good a speed of at least 2 knots for 25 person.
-Before lowering lifeboat, battery-charging connection should be disconnected, if provided.
Regulation for the life boat hook:
-For ship built after Jan 2014 to provide hook stability the release mechanism shall be designed so that when it is fully in the close position.
-The weight of the life boat does not cause any force to be transmitted to the operating mechanism.
-Locking device shall be designed that they can not turn to open due to forces from the hook load.
-If a hydrosyatic interlock is provide, it shall automatically reset upon lifting the boat from the water.
Specialty of Tanker lifeboats.

Launching of life boat:
https://www.youtube.com/watch?v=MZLkiTwh10M
1.. Remove battery charging plug close drain plug remove overlashing wire rope fitted check painter rope if fitted .
2.go inside and start one battery, before entering the lifeboat ensure that forward and aft hook release lever are pointing to the green safe position .
3. Three securing pin must take out two each on forward and aft on cradle stopper and one pin in break governor.
4.from outside just lift the brake Governor or deadman handle or holding brake or it can be done from inside the lifeboat also..
5.The boat along with cradle slides down till it comes to the embarkation deck
6. remove the gripe wire if fitted carryout pre-launch check
7.by pulling tricing pendant bring it alongside to the embarkation Deck
8. allow crew to enter the lifeboat and ensure all crew are strapped in.
9. now lower the lifeboat by the wire connected to the brake governor or from outside also it can be lowered lower the lifeboat until the keel is just above the water
10.instruct two crew one forward and one aft to remove the green handle locking pin from the hook.
11. lower the lifeboat by Coxwain release handle .on contact with water ensuring the lifeboat is totally waterborne remove the safety pin from Coxwain release handle assembly confirm via inspection window that the hydrostatic interlock unit has operated successful in moving the emergency interlock handle to the open position that is in red area, lift the cocks when release handle up against the reaction of the return spring until the spigot pins are clear of the side plates lot then pull the handle back to its fullest and not proceed to sail away .

Emergency release on load release procedure-
In situation where the lifeboat is waterborne and the safety pins from the coxwain release handle assembly has been removed but the hydrostatic interlock unit has failed to move the emergency interlock handle into the open position or red area the following process your must be adopted the procedure is same for the onload release where the lifeboat is not waterbourne.
1. break the inspection window glass to gain access to the emergency interlock handle and push it upward and hold it in open position that is in red area.
2. lift the cockswain release handle up (against the reaction of the return spring) until the spigots pins are clear of the side plates slots then pull the handle back to its fullest extent .
12.release the painter release by release printer handle.
13. letting go 1. start engine 2.if in dangerous atmosphere open air supply in water spray valve 3. release painter when ready4. stay away from ship.
14. Final action 1. rescue any swimming survivor it safe to do so 2.when clear of vessels stream sea anchor 3. operate EPIRB and SART.
Condition of Off load mechanism
The off load mechanism releases the boat after the load of the boat is transferred to water or the boat has been lowered fully into the sea.When the boat touches the surface of water, the load on the fall and hence the hook releases and due to its mechanism the hook detaches from the fall. If the detachment dose not takes place, any
of the crew members can remove the hook from the fall.
Most of the times the offload mechanism is manually disengaged in case of malfunction; however, in case of fire, it is dangerous to go out and release the hook
Surveyor asking some time as an engineer what is your checks while Lowering life boat:
-before lower life boat check battery is properly charged.?
-Rudder is turning on both port and stbd side.
-Check fuel tank, fuel pipe, lube oil level.
-Check air bottle pressure.
-Ensure engine running in both direction means fwd and astern.
-Electrical connection checks.
Types of brake on lifeboat
1.centrifugal brake
2. dead man handle or holding brake.
There are two type of brake- holding break and centrifugal break. Holding break is designed to stop and hold the lifeboat stationery at any point between its fully house position in the debit or when it is near the water edge. The holding break is engaged by lifting the weighted break handle thus allowing the lifeboat to descend downward towards the water. Centrifugal brake is provided to control the rate at which the life boat is lowered. This limit the rate of descent of the boat, when the hand brake is not engaged. Brake shoe of calculated weight acts on the inner surface of the stationary drum being thrown out word by centrifugal effect against the restraining spring delivering speed is 36 metre per minute.
