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 ...
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]
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.

In classical mechanics, free fall is any motion of a body where gravity is the only force acting upon it. A freely falling object may not necessarily be falling down in the vertical direction . An object moving upwards might not normally be considered to be falling, but if it is subject to only the force of gravity, it is said to be in free fall.

A rescue lifeboat is a boat rescue craft which is used to attend a vessel in distress, or its survivors, to rescue crew and passengers. It can be hand pulled, sail powered or powered by an engine. Lifeboats may be rigid, inflatable or rigid-inflatable combination-hulled vessels.
