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.
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 ...
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]

Between 1948 and 1952 a further four boats were built before attention turned to the much modified 42ft Watson type which appeared in 1954.
Saturation diving is normally done from a saturation system on a diving support vessel or an offshore platform.While under saturation, the divers cannot be decompressed quickly in response to an emergency as that would be rapidly fatal, and though unusual, emergencies requiring personnel evacuation have occurred on such platforms due to extreme weather or accidents.
The free-fall time is the characteristic time that would take a body to collapse under its own gravitational attraction, if no other forces existed to oppose the collapse.. As such, it plays a fundamental role in setting the timescale for a wide variety of astrophysical processes—from star formation to helioseismology to supernovae—in which gravity plays a dominant ro
The 44-foot motor lifeboat was the standard workhorse of the United States Coast Guard (USCG) rescue boat fleet. [1] The 44′ MLB has been replaced by the 47′ MLB. [2] The boats are powered by twin diesel engines, each powering a separate propeller.
