Offshore Charging Vessel Project Takes Off

A consortium of offshore renewable energy and marine companies are exploring the viability of developing an offshore charging facility for electrified vessels.

Funded by the first phase of the UK Government’s Sustainable Innovation Fund, the project – led by Turbulent Simulations, alongside Aluminium Marine Consultants, the Offshore Renewable Energy (ORE) Catapult, MJR Power & Automation, Tidal Transit, and Bibby Marine Services – will look into the design of a permanently stationed Offshore Charging Vessel.

The technology would allow electrified vessels, such as Crew Transfer Vessels (CTVs) and Service Operating Vessels (SOVs), to dock and recharge whilst operating offshore, giving them greater range and bigger operating windows.

The charging vessel would, in turn, draw power from wind farms at times of low demand, storing it in onboard batteries.

The project partners will also explore the potential for the charging vessel to store modular battery units that could be swapped for the used battery on the operating vessel.

Trevor Linn, CEO of Turbulent Simulations, said: “We’re excited to be working with leading offshore wind industry partners and bring our knowledge and experience of software and digital integration to bear in tackling the challenge of offshore charging. We see huge potential and strong market demand for this innovative technology as the offshore wind industry and the broader maritime sector seek solutions for charging the next generation of electric and hybrid service vessels.”

Having a charging capability offshore should bolster an owner/operator’s confidence to invest in electrified vessels, which will have greater flexibility to operate in the field for longer periods, supporting a reduction in operations and maintenance costs, the consortium said.

“ORE Catapult recognises the strong industry demand for clean maritime solutions to help the industry reduce its emissions during the operations and maintenance of offshore wind farms,” Stuart Barnes, Regional Partnership Manager at ORE Catapult, said.

”Early indications suggest that electric and hybrid CTVs are gaining popularity among operators and an important enabler to unleash their full potential is the capability to charge offshore. Delivering this capability requires a number of technical, commercial and regulatory barriers to be addressed and ORE Catapult is pleased to be working with this group of highly skilled UK SMEs involved in bringing forward this innovation.”

The project is backed by industry advisers, including Vattenfall Networks, Vattenfall Renewables, and the Workboat Association (WA). The consortium is also hoping to advance to the second phase of the Sustainable Innovation Fund, potentially accessing GBP 3 million of grant funding to undertake a detailed design and demonstration of the charging vessel.

“As a vessel operator actively pursuing net-zero maritime operations, we believe that offshore charging capability is an important enabler to the rapid deployment of electric and hybrid electric vessels in offshore wind,” Leo Hambro, Director at Tidal Transit said.

”As such we take a great interest in this emerging technology and we’re very pleased to be providing direct support to the development of this important innovation.”
