Ørsted will have three new hybrid CTVs to assist with the construction work at the Hornsea Two offshore wind farm writes Dag Pike.

NOS’s Energiza will be powered by four MTU 720kW diesels powering Helseth CP propellers

Northern Offshore Services (NOS) will have its 34 metre Energizer available this spring and two 35 metre vessels operated by MHO-Co are due to start work this summer. The vessels will be based at the Hornsea operations base at Grimsby with a four hour journey out to the wind farm site.

These three CTVs will use hybrid propulsion systems and according to Ørsted, the batteries installed on the vessels can be recharged either by power surplus from the onboard generators or via a recharging buoy system that is being tested during the construction phase of the wind farm. All three vessels have been designed to be able to accommodate fuel-cell technology once suitable storage for the fuels such as hydrogen or methanol has been developed for use onboard.

The three CTVs will also be fitted with the newly developed Z-Bridge motion-compensated transfer system which is called Bring-to-Work. This low weight transfer system is designed to enable technicians to transfer to the turbine tower in safety from the deck of the CTV.

“Designing and building hybrid CTVs is a huge step in the environmental direction, and I am proud that we at MHO.Co have found partners who share our vision for sustainable development in the offshore industry.” says CEO and Founder of MHO-Co, Mik Henriksen.

MHO-Co has chosen to install Danfoss’ Editron as the propulsion system on the catamarans. The system’s permanently magnetized electric motor saves both weight and space on the CTV while consuming less power and giving higher efficiency. These CTVs are being built at the Afai Southern Shipyard in China with the design developed by Mik Henriksen in cooperation with Incat Crowther. NOS’s Energiza will be powered by four MTU 720 kW diesels powering Helseth CP propellers and with its battery bank supplied by Corvus Energy.

Ørsted’s 1.4gW Hornsea Two will comprise 165 Siemens Gamesa 8mW turbines which are scheduled to be commissioned in 2022.
