Our recent project at Grimsby Fish Dock saw the supply and installation of a bespoke heavy-duty EV CTV pontoon system, purpose-built to support the UK’s first all-electric Crew Transfer Vessels (CTVs).

Commissioned by Grimsby Fish Dock Enterprises to provide a state-of-the-art floating charging facility for the first electrically powered CTV in UK Waters, this facility – located on the Humber estuary – is ideally placed to support operations servicing North Sea wind farms, including Hornsea, Triton Knoll and Dogger Bank.
Working closely with the client, we designed and manufactured a 24m x 3m robust pontoon system complete with an integrated mooring system and access gangway, which incorporates a heavy Duty 200mm D Fender for energy-absorption on berthing and a hardwood drop-down fender to protect the floats.
The pontoon system provides a stable platform that is capable of accommodating the significant cabling and additional weight of the E-CTV charging equipment that weighs around 400kg. Designed for high-traffic commercial use, the pontoon also features advanced electrical infrastructure to accommodate high-capacity EV chargers – enabling fast, efficient charging directly at berth.
To complete the installation, subcontractor 3RS oversaw full project management; coordinating vessel craneage, placement of anchor blocks, mooring chain installation and the fitting of the brow bearing and gangway. The EV CTV pontoon system is now in full operation, serving the region’s pioneering electric CTVs.
The new EV CTV pontoon features non-slip GRP decking on both the platform and gangway, providing secure footing in all conditions, and is expected to benefit CTV crews who will use the facility multiple times a day.
