North Sea Winches have a wealth of experience in the design, manufacture, commissioning and after sales support for back deck equipment of cable installation vessels. We recently completed delivery & commissioning of a state-of-the-art quadrant handling system for offshore contractor DeepOcean to aid installation of array cables on both Race Bank & Bligh Bank (Belwind) off the coast of Norfolk & Zeebrugge, respectively.
Working for a leading international company, DeepOcean has delivered class leading efficiency completing inter array cable installations from the vessel Maersk Recorder for the UK east coast wind farm developments.
Working closely with DeepOcean from concept through to commission, NSW supplied equipment including a 20-tonne active heave compensated winch, a 5-tonne constant tension winch and three 110kW EHPU’s to operate the two winches and an over boarding A-frame on the vessel. The new equipment has greatly improved cable lay times, of at least two completed lays in a 24-hour period dramatically saving time and ultimately cost whilst improving project schedule lead times for DeepOcean. Lee Smith DeepOcean project manager said:
“This project is one of the first combined active heave/constant tension deck layouts for NSW and it has proved their abilities beyond doubt. The winches and controls were installed over a 10-day mobilisation and then put straight into operation on a time-critical deployment,
where everything went according to plan”.
Some of the performance data for the package include:
