Marine engineering consultancy BAR Technologies has officially launched its first BARTech 30 crew transfer vessel (CTV) for UK offshore company Seacat Services.

Seacat Columbia, built by Diverse Marine, was designed to address the two most pressing challenges of the offshore wind industry: vessel efficiency – and therefore emissions reduction – and the comfort in transfer, and subsequent effectiveness, of offshore wind engineers. 

In the first instance, many major offshore wind developers and owners are looking at fossil fuel consumption in wind farm service vessels. Secondly, as personnel beset by sea-sickness in travel to a project must be returned to port, any such occurrence means expensive downtime for the project owner.

With its 30m ProA design, and active foiling systems to correct for pitch and roll, the BARTech 30 is able to minimise 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 the UK’s growing fleet of offshore wind farms. Additionally, 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.

Martin Whitmarsh, Chair, BAR Technologies, said: “BAR Technologies was established to leverage the highest level of engineering expertise and understanding of hydrodynamics from the fields of Formula 1 racing and the Americas Cup respectively, to take on some of the biggest challenges in vessel efficiency and maritime decarbonisation. Alongside our pioneering wind propulsion technology for the shipping industry, our latest developments in crew transfer vessel design, demonstrated by the BARTech 30, are helping to significantly mitigate the ‘last mile’ of carbon emissions in offshore wind development and construction. We know that the offshore wind industry has led several innovations in cost reduction since its inception.  We’re now able to take this efficiency drive one step further with a vessel design not only able to operate in wider offshore parameters  and presenting new savings in servicing and maintenance, but, also combined with a significant reduction in fuel consumption.”

John Cooper, BAR CEO, said: “Following our preview of the vessel at the Seawork maritime event in June, we’re thrilled to officially launch the BARTech 30 here at our home in The Camber in Portsmouth. Having our first customer delivery is a key milestone in our development of the BARTech 30 programme, and we look forward to seeing further customer orders for the vessel fulfilled in the near future. In taking this pioneering design to market, we’ve been able to bring in elements of collaboration from other South Coast marine designers and consultancies – and the Isle of Wight based vessel manufacturer – helping to secure a domestic supply chain for a key part of the UK offshore wind industry.”

As previously reported, alongside the order for two vessels from Seacat Services, innovative CTV operator High Speed Transfers has ordered two BARTech 30s.
