Feasibility of Using Commercial-Off-the-Shelf Ruggedized Laptop Computers and Independent Power Sources in a Disabled Submarine

Abstract

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.
