Submarine Escape Immersion Equipment

Submarine Escape Immersion Equipment (SEIE), also known as Submarine Escape and Immersion Equipment, is a whole-body suit and one-man life raft, designed by British company RFD Beaufort Limited, that allows submariners to escape from a sunken submarine. The suit provides protection against hypothermia and is rapidly replacing the Steinke hood rescue device. The suit allows survivors to escape a disabled submarine at depths down to 600 feet (183 m), with an ascent speed of 2-3 meters/second, at a rate of eight or more sailors per hour.
