Custom work ROV

Custom work ROV

This ROV was designed and built for deep ocean survey, debris field mapping, artifact recovery, salvage, and underwater excavation. It included specialized manipulator tooling and camera systems to support meticulous documentation and collection of artifacts and marine specimens.

Dynamic positioning thruster

Dynamic positioning thruster

This project consisted of redesign and retrofit of a fluid swivel and top-end hinge support for a pair of 500-hp omni-directional ship’s thrusters. The thrusters were used for dynamic positioning of a 185′ research vessel. The fluid swivel supported 6000 psi hydraulic pressure and included a pair of 2-inch primary flow ports plus case return and position feedback sensor.

Hydraulic power unit

Marine hydraulic power unit

This 120-hp, 5000-psi, variable-flow marine HPU is designed to power a pair of 50-hp dynamic positioning thrusters as well as other auxiliary hydraulic requirements. Pump output control is integrated with the vessel navigation control system. The unit was designed for air transport.

Hydraulic thruster

Outboard hydraulic thruster

These 50-hp, 5000-psi hydraulic thrusters were custom designed for on-water propulsion and dynamic positioning of an amphibious aircraft. They provide 360° continuous azimuth capability with heading feedback for integration with the satellite navigation system. Special features support manual through-hatch deployment and attachment.

ROV launch system

ROV launch and recovery system

This task included design upgrades, installation, operation, and maintenance of the launch and recovery system for a 12,000 lb. work ROV. Efforts resulted in significant increases in reliability and sea-state operating window.
