Abstract:

A set of three rugged divers tools - rotary impact tool, a bandsaw, and a rotary disk tool - each powered by an interchangeable 3-horsepower seawater hydraulic motor, have been developed for the construction diver. The tools are supplied hydraulic power by a high-pressure seawater pump driven by a diesel engine. This pump provides filtered seawater at 14 gpm and 2,000 psi in an open circuit system. The objective for developing the Multi-Function Tool System MFTS was to provide Underwater Construction Teams UCTs with a tool system to meet their operational needs and operate safely without contaminating the environment. This MFTS is environmentally neutral, and the single hose requires less physical effort to control, particularly in ocean currents. The diver tools are made of materials that resist sea water corrosion, allow sea water to act as lubricants and that require little field maintenance. Test and evaluation is conducted for operability, safety, reliability, maintainability, and availability.
