Holes on the edges of the plate fit over these bolts and the cover is fastened down with nuts or dogs. Vapor accidents can occur when pressure builds up in the tank below and the Butterworth cover is carelessly removed. [5] Butterworth hatches have been responsible for a number of marine losses. [6]
RNLI inshore rescue boat during Falmouth Lifeboat Day, August 2006. A rigid inflatable boat (RIB), also rigid-hull inflatable boat or rigid-hulled inflatable boat (RHIB), is a lightweight but high-performance and high-capacity boat constructed with a rigid hull bottom joined to side-forming air tubes that are inflated with air to a high pressure so as to give the sides resilient rigidity along ...
A composite overwrapped pressure vessel (COPV) is a vessel consisting of a thin, non-structural liner wrapped with a structural fiber composite, designed to hold a fluid under pressure. The liner provides a barrier between the fluid and the composite, preventing leaks (which can occur through matrix microcracks which do not cause structural ...
Some inflatable boats can be disassembled and packed into a small volume, so that they can be easily stored and transported. The boat, when inflated, is kept rigid cross-ways by a foldable removable thwart. This feature makes these boats suitable for liferafts for larger boats or aircraft, and for travel or recreational purposes.
The tanks must be designed to safety standards appropriate for a pressure vessel, such as ISO 11439. [6]The pressure vessels or air storage tanks that can be used in compressed-air vehicles can be made for low pressure (9 atm (130 psi)) or high (more than 240 atm (3,500 psi)), and can be made of composite materials like thermoplastic and fiber-reinforced thermoplastics, [7] [8] that means that ...

The small unit riverine craft (SURC) is a rigid-hull, armed and armored patrol boat used by the U.S. Marines and U.S. Navy to maintain control of rivers and inland waterways. They are similar in size and purpose to the much older Patrol Boat, River vessels used during the Vietnam War .
