This is a subsea jetting sled operational since 1984, modified and redesigned for the trenching of submarine utility cables. It is capable of jetting or mechanically trenching cables to a burial depth of approximately 2 meters and can be operated in subsea water depths of 50 meters. It has an optional 3 meter burial injector tool with a hydraulic trencher. The sled can also provide a complete navigation package with personnel including real time burial depth, pitch and roll interface with GPS at survey grade accuracy with as-built. It can provide a complete containerized operational cable management system with control room, winch, motorized cable reels, heave tensioners, jet pumps, tension-meters including a LARS (a launch & recovery system).
The system has an Hydraulically Articulated Cable Injector that can adapt to different depth, length and width of power or Fiber Optic Cables including the option of a Hydraulic and mechanical trencher attachment for non-fluidized soil such as clay, cobbles or corrals.
The Hydraulic Reel System 12'x12'x12' can carry over 20 Kilometres of 1" Cable or 6,000' of 4" wire. It is totally self-contained with Hydraulic control for the Jet Sled and has small Hydraulic Winches for holding the Jet Sled in position under water. The minimal deck space required is 14' wide x 40' long.
