Offshore Wind: BAR Targets U.S. Crew Transfer Vessel Deployment for 2024

Marine engineering consultancy, BAR Technologies (BAR), said Wednesday that its low-emission crew transfer vessel (CTV) design, the BARTech 30, will be available for the first U.S. offshore wind projects in 2024, following quotes at several U.S. shipyards.

BAR said Wednesday it was meeting with the U.S. offshore wind vessel supply chain at a workboat show in New Orleans this week in anticipation of license agreements that will see the CTV type built in the U.S.

"As the nascent U.S. offshore wind industry starts to firm up project timeframes, there is the opportunity for developers to capitalise on the latest low carbon and fuel-efficient designs for offshore wind workboats and crew transfer vessels, leapfrogging many of the legacy, less efficient designs that have stemmed from European offshore wind development," BAR said.

"With the Biden Administration targeting up to 30GW for the US offshore wind market, and with many of these projects far out to sea, the diesel fuel burn for workboat operators serving the market can be significant.  More efficient CTV designs, however, that either utilise the retrofit of efficient technologies, like foiling, or encompass entirely new hull-forms, present an opportunity to save operators significant fuel costs," the company said.

Additionally, BAR said, with the U.S. offshore wind market comprising a number of European developers managing joint venture projects, the focus in the European markets on emission reduction will, in time, also become a part of the U.S. offshore wind industry.

As the U.S. offshore wind market rapidly accelerates, BAR says, there is a real opportunity to bypass some of the more drawn-out learning processes that are only now enabling more efficient, lower carbon emitting CTVs to become operational in Europe.

"With significant interest in the domestic U.S. licensing of the BARTech 30 CTV – a type already on charter at the UK’s Sheringham Shoal offshore wind farm – BAR anticipates its vessel design will be available to support the first major U.S. offshore projects as they head into construction," the company said.

“The U.S. offshore wind market has huge potential,” said John Cooper, Chief Executive Officer, BAR Technologies.  “But that potential isn’t limited to the scale of its projects and rapid pace of development. Equally, there is a massive opportunity to circumvent many of the quite protracted processes for growth – and one of these is in the rapid deployment of the latest greener and leaner, workboat vessels.”

 “In the European markets, a number of forward-thinking wind farm operators are recognising not only the significant opportunity to reduce fuel burn across the fleets serving their projects, but also the reputational risk in continuing to use outmoded inefficient vessel designs.”

“With some of these same operators now developing projects in a new market, we anticipate a number will be looking to capitalize on some of the innovations they have in Europe, in the U.S.”

According to the company, with its 30m ProA design, and active foiling systems to correct for pitch and roll, the BARTech 30 is able to minimize vessel motion and fuel burn – leading to an average increase in stability across all sea states of up to 70% and a reduction in total emissions of 30% over a typical operational profile - making the vessel one of the first Low Emission Vehicles (LEVs) serving offshore wind farms.

Additionally, BAR says, with the vessel able to operate in more challenging conditions than the current catamaran designs, offshore wind turbines may be serviced over a greater number of sea states, ensuring wind farm owners have more opportunities to better and more cost-effectively provide turbine maintenance.
