Abstract:

A program was conducted to conceive a diver platform capable of supporting working divers to 2500 FSW. The program concentrated on the development of hardware, equipment, and mission requirements the physiological limitations of man at this depth was not part of the work effort. Primary systems considered include diver platforms, a semi-submersible support craft with associated deck equipment, and the umbilical interface. Early in the program the scope was narrowed from a study of all types of diver platforms to consideration only of tethered platforms. Realistic mission requirements were defined that include two situations short saturation dives less than 24 hours and longer saturation dives 1-14 days. By comparing different platform concepts, a preferred two-chamber configuration was recommended. The report describes detailed requirements for handling, gas, power, communication, instrumentation, umbilicals, and deck equipment. Of the equipment recommended for use at 2500 FSW, some is state of the art and the remainder requires research and development for use at that depth. Modified author abstract
