Jet Trencher Module (JTM) for WROV

The JTM700 system is an independently supplied and controlled jetting package that incorporates an industry standard WROV system within its frame. The WROV supplies the station keeping and general maneuvering functions as well as surveillance and manipulator operations. The JTM700 has its own jetting pumps and hydraulic power units to provide all the JTM functions so as not to require any supplies or control from the WROV.

The JTM700 package includes its own control system and power distribution arrangement. Power and control for the combined WROV and JTM700 system is fed through a single umbilical that is distributed once it arrives at the JTM700.

Note: this is a new-build product that can be tailored to customer needs.
