This project evaluated two commercial-off the-shelf COTS laptop computer systems and two power supplies for ruggedness and performance under conditions expected aboard a disabled submarine DISSUB for potential use with the Submarine Escape and Rescue Expert SEAREX computer program. Computers and power supplies were tested in hyperbaric chambers at Naval Submarine Medical Research Laboratory NSMRL under hyperbaric 5 bar, high humidity 80 and low temperature 45F conditions simulating a DISSUB. One of the two laptop computer systems tested met all requirements. The other failed due to the failure of its keyboard. The lead-acid battery design tested supplied sufficient power to energize a computer for nearly five days and the alkaline battery pack lasted for nearly seven days. This testing demonstrated that COTS hardware capable of supporting SEAREX in a DISSUB is nearly available.
