Proteus Active Heave Compensator
The Proteus is an Active Heave Compensator or AHC designed to reduce or eliminate the effects of vessel heave during overboarding operations. The Proteus can hold a package at a specific location in the water without the vessel's motion on the waves compromising the position.
Deep Down Marine Technologies was approached to implement an algorithm to perform Active Heave Compensation. The customer identified the operational tolerance of the system to be 6" of movement of the package with vessel heave of approximately 20 feet. The system we implemented is accurate to .6" of package movement with vessel heave up to 30 feet. We always deliver the best products, often exceeding customer requirements and expectations.
Deep Down Marine Technologies implemented an Allen Bradley PLC system to derive vessel heave data from a Motion Reference Unit (MRU) and translate the data into valve control signals that drive hydraulic actuators to compensate for the movement of the vessel. The Proteus sits in-line with a winch coupled with Deep Down's In-Line Active Heave Compensator.
The Proteus has been successfully tested and delivered. We can provide an Active Heave Compensation solution for any overboarding operation.
