The hydraulic circuit has been designed to ensure that the docking latches cannot be released before the connector plate. When the ROV and the Track Base are connected, the Centaur utilizes the 150-shaft hp Innovator motor and the additional Track Base motor, which is equal to the ROV motor. The Innovator electric motor drives a dedicated pump on its second shaft. The same size as the vehicle's primary pump, the dedicated pump absorbs the full motor capacity and directly feeds the Centaur hydraulic system through the wet mateable connector plate without wasting power in the additional Isolated Hydraulic Power Unit. System functions include mainly the LP water pump as well as track locomotion, jetting tool deployment, and auxiliaries.
Electrical power is provided through wet mateable couplers mounted on the connector plate.
Focused on maximizing efficiency, this design results in a 300-hp overall power of the trenching tool. The Interface Skid is attached underneath the ROV by means of pinned connections along its four vertical columns using the ROV standard tool interfaces. The Interface Skid functions are actuated by the ROV controls and subordinate to the hydraulic system. The Interface Skid engages the Track Base by means of two front docking latches and two lift pins located halfway along the skid close to the center of gravity. The lift pins are passive, while the docking cones are driven hydraulically and controlled by a fail-safe mechanism.
