The (enclosed) lifeboat is on a ramp and slides down and off of the ship when engaged. This is done by pumping a lever that is inside the lifeboat by the pilot. [ 9 ] If there is not enough hydraulic pressure to release the stop fall, a pump on the inside must be rotated to build up the hydraulic pressure to release the lifeboats stopfall hook.
Lifeboat capacity is specified [5] and listed on the ship's "safety equipment certificate". Further details of the boats are found in "Form E" of this certificate. [citation needed] Ships fitted with "free fall" lifeboats are an exception – they have only one boat, at the stern. [citation needed]
TEMPSC Lifeboat in Bristol harbour, England. TEMPSC is an acronym for "Totally Enclosed Motor Propelled Survival Craft", which was originally designed for offshore oil and gas platforms in 1968. The first-ever TEMPSC was spherical in shape, had a flat bottom, a single hook, with a total passenger capacity of 28 passengers and a fire-retardant ...
These include float-off, lowering from davits, free-fall, crane launch. The systems available should be operable in the full range of expected operating and plausible emergency conditions, which apply to the vessel or platform's other emergency evacuation equipment, and designed to accommodate snatch loads.

The Shannon launch and recovery system (SLARS) was developed to launch and recover the 18-tonne Shannon-class RNLI lifeboat. [3] [4] SLARS SC-T08 with the St Ives lifeboat Nora Stachura. The lifeboat is launched, and recovered, bow-first. The carriage, mounted on tracked wheels, is used to transport a lifeboat from boathouse to sea.
Launch of a free-fall lifeboat. Since December 2004, Panamax and Capesize bulk carriers have been required to carry free-fall lifeboats located on the stern, behind the deckhouse. [7] This arrangement allows the crew to abandon ship quickly in case of a catastrophic emergency. [96]
Fowler Challenger III is a continuous track amphibious launch tractor, which was specifically designed for the Royal National Lifeboat Institution (RNLI), to launch and recover carriage mounted lifeboats, from beach-launched lifeboat stations. Fowler Challenger III Crawler Tractor Mick Bell
Under normal launch conditions the lifeboat is loaded with its bow to the rear of the carriage to allow faster deployment. When the lifeboat is recovered it reverses back on to the launch bed. [3] Depending on the sea condition the helmsman require good seamanship to achieve this.
