ThrustMaster
The ThrustMaster is a high performance thruster control unit for large ROV’s, trenchers and similar vehicles. It’s a robust design suitable for most hydraulic work class ROV systems.
Description
The thruster control unit is provided using 6 high-flow proportional control valves. One proportional pressure reducing valve is available for controlling the HPU pump pressure. The number and type of valves can be changed according to customer needs. All thruster control is based on direct communication with a pressure tolerant electronic valve driver card mounted in the valve block. This removes the need for a big electronic pressure vessel for control electronics, and large and expensive cables to the valve pack. All that is needed is a 24VDC power supply and serial line.
The ThrustMaster 6 is also equipped with instrumentation for monitoring parameters such as hydraulic pressure, water depth, HPU-temperature, leak sensors and reservoir level sensors. The concept of using proportional valve technology instead of servo valves for thruster control results in higher hydraulic efficiency, reducing overall power requirements of hydraulic power units. Proportional valves have insignificant internal leakage in the valve and low pressure drop at high flow compared to servo valves. This, combined with the design of the valve block, reduces the hydraulic power loss in each valve and increases overall hydraulic efficiency.
ThrustMaster 6 can be combined with additional thruster control units or other intelligent valve packs in a network. The unit communicates with Innova`s product line of pressure tolerant controller boards and control systems to provide a complete control system concept.
