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.
Operates as self propelled by the resultant jet reaction force or as a light weight towed sled dependent on operational factors. Equipped with three sets of exchangeable burial tools for 1mt, 1.5mt, 2mt Burial Depth (Numerous of jetting injectors from 12mm to 24 mm determined by soil type).
