Waterjets to power offshore wind vessels

Five offshore wind farm vessels are undergoing a major refit to enable them to operate with waterjets.

Waterjet technology

HamiltonJet is currently collaborating with Norway-based Offshore Windservice AS to convert five vessels from CPP propeller to waterjet propulsion and advanced control technology. At project completion, all five vessels will feature twin HM721 waterjets coupled with HamiltonJet’s intuitive AVX controls.

HamiltonJet CEO, Ben Reed, said: “It’s the first time these two products have been paired together, and the first time we’ve put waterjets of this size into a Wind Farm vessel. It means these boats will really power along.”

Retrofit solution

For the Offshore Windservice AS project, HamiltonJet devised a creative solution to retrofit waterjet technology into the existing fleet.

“This clearly shows you don’t have to buy a new boat when a refit meets the brief. It’s the kind of thinking we apply to all our projects and one of the reasons people trust us to get the right result for them,” said Mr Reed.

With one vessel complete and the second underway, Offshore Windservice AS is progressing the refit at a good pace.

“We actually ended up installing the waterjets on the first vessel ourselves, and it couldn’t have been easier,” said Billy Thøger Kristensen, chief operating officer at Offshore Windservice AS.

Speaking about HamiltonJet’s future-ready AVX control system, he said: “With AVX we’re able to access HamiltonJet’s JETanchor system, the best hands-free technology on the market. It’s two operational modes of Station Keeping and Virtual Anchor greatly simplify the job of our skippers in open water.
