GE’s Marine Solutions to power DSV

The DSV is believed to be the world’s first with a multi-saturation diving system and will enable diving operations at a depth of up to 500m and salvage work at 6,000m deep. It will be used for deep-water salvage operations, deep-water pipelay and construction.

Huang Yan, project director at SSB, said: “This vessel will be the best of its class anywhere in the world. The sophisticated electrical system, including an innovative closed-ring arrangement of the propulsion switchboard, is a top priority for us to achieve our design goals.

“We are pleased to work with GE to ensure that the deep-water DSV will be one of the most advanced of its kind in the world.”

The vessel will feature GE’s SeaStream DP system (Class 3), created to safely and efficiently control the ship’s position and orientation. It will use multidirectional thrusters and sensors to monitor real-time wind, current and wave conditions, as well as automatically activating the propulsion units to counteract environmental forces.

The company said its ‘Ecomagination’ energy-efficient mode uses advanced algorithms to optimise vessel heading and the number of generators needed for operation, reducing power consumption, operational costs and emissions.

The vessel will be powered by an electric power and propulsion system, including GE’s 4,656-kilowatt generators, switchboards and medium-voltage frequency drive propulsion controllers as well as a vessel automation and control system.
