World leading ROV manufacturer Sub-Atlantic Ltd has completed the assembly and integration of a power and control system to an underwater trenching vehicle for CT Offshore of Denmark.

The £500,000 project, which took just six weeks to complete, was a departure from the normal type of system built in the Aberdeen factory

The tracked vehicle is believed to be one of the most compact systems ever built. Its first deployment will be aboard the DP vessel MV Nico working on a wind farm in the UK sector of the North Sea.

The bespoke system was designed by CT Offshore and GEO Marine with specialist input on propulsion and advanced control systems from Sub-Atlantic Ltd, specifically for operating in the hostile near-shore environment of fast moving, turbid waters.

The vehicle uses a Sub-Atlantic surface transformer running Comanche ROV power train comprising four horizontal and three vertical SPE 250 brushless thrusters. The Sub-Atlantic supplied surface control unit operates subCAN™ control software for advanced operations and diagnostics down to PCB component level and employs a specialist survey pod for control and diagnosis of the survey sensor suite. Sub-Atlantic built hydraulic power units, motor and compensators were also integrated into the vehicle.

CT Offshore CEO Paw Cortes said: “We chose Sub-Atlantic Ltd as our preferred partner in this project because of their vast experience in finding creative solutions to sustained operations in unusual and extreme environments. The willingness and ability of Sub-Atlantic engineers to think ‘outside of the box’ made it an easy decision for this joint venture.”

Sub-Atlantic Ltd general manager John Ferguson said: “This has been yet another unusual and challenging engineering project for which we have a growing reputation. The speed and the success of project completion was due to the dedication, skills and innovative thinking of both Sub-Atlantic engineers and the CT Offshore Project team and we look forward to future partnership opportunities.”

CT Offshore are based in Odense, Denmark, and provide consultancy, installation, seabed survey and a variety of ROV/trenching/shipping services to the offshore wind farm Industry.

Sub-Atlantic is part of Triton Group, an international group of businesses offering a range of control system based products and systems with complementary services. Products include the widest range of market leading electric and hydraulic ROVs for inspection, survey and light intervention applications through to deepwater heavy construction applications.
