Water Jets Bring Safety for Offshore Wind

Rolls-Royce said today in a press announcement that it will supply water jets for three wind farm support vessels, (one 24-meter and two 26-meter aluminum catamarans) to be built by South Boats IOW for the offshore wind transfer vessel operator Seacat Services.

Rolls-Royce labeled the contract as “one of the biggest orders made for wind farm workboats,” and all three newbuilds will feature two Rolls-Royce 56A3 stainless steel water jets as well as Rolls-Royce’s new compact control system tailored to suit owners’ requirements and reduce build/installation times.

The new wind farm workboats will include MTU 12V 2000 engines which will power the catamarans to speeds of up to 30 knots. Once in operation, the catamarans will be used for people and cargo transfers to the growing number of offshore wind farms around the coast of Europe.

When factoring the water jets’ properties into the vessels’ overall design, the propulsion system contributes a safety element needed especially when transferring crew and equipment onto turbine structures. According to Rolls-Royce, “water jet technology offers a combination of speed, efficiency and excellent maneuverability for these vessels, which will regularly operate in challenging sea conditions with strong winds and currents.”

“Reliability and performance are of utmost importance in our industry and are how all vessels are measured, which is why we choose Rolls-Royce water jet units,” said Ben Colman, Sales & Marketing Manager, Alicat Workboats Ltd. & South Boats IOW Ltd., “With the A3-series we have found excellent performance with speeds higher than predicted with excellent fuel efficiency as a result.”

Coleman mentioned that the A-3 series’ reliability has led his company to fit some 20 Rolls-Royce water jet units over the last few years.
