Caterpillar Marine has been chosen as power solutions provider for the six new offshore wind vessels being built for Edda Wind at the Gondan and Balenciaga shipyards in Spain.

Edda Wind, a joint venture between Østensjø Rederi and Willhelmsen, has orderred a series of four new Commissioning Service Operation Vessels (CSOVs) from Astilleros Gondán and two new Service Operation Vessels (SOV) to be built at Astilleros Balenciaga. The six vessels are scheduled to be delivered in 2022-2024. Of the six confirmed units, the first four in the series have been contracted to work on offshore wind farms under long-term agreements with Ørsted, Vestas and Ocean Breeze. Together with their partners, Edda Wind is working on developing new technologies based on hydrogen as a safe and efficient energy source. These new vessels are prepared for the future installation of hydrogen power, which will turn the CSOV/SOVs into zero emission vessels without compromising operational capabilities.

The preparations for future zero emission propulsion systems are made possible by the Norwegian Enova funding program. The upgrades include complete tank systems for hydrogen storage, dedicated machinery space for fuel cells, battery hybrid system, novel type propulsors, and an extensive package of energy saving measures for most auxiliary systems such as HVAC and pumps systems.

Edda Wind CEO Kenneth Walland said: “Ordering more purpose-built CSOVs will further strengthen Edda Wind’s leading position within offshore wind. Tremendous growth is expected in the offshore wind segment over the next decades, and Edda Wind intends to be a world-leading provider in this segment.” The Edda Wind series of CSOV/SOVs are each powered by three 1700 kWe Cat 3512E gensets, which together with other energy saving equipment will significantly reduce the emission of greenhouse gases. The generator sets are configured for variable speed operation and are integrated to the electric hybrid system for the vessel with a special configured Cat control cabinet. This combination of Cat variable speed operation and Cat SCR with IMO III emissions certification will enable high efficiency over the complete power range with claimed emission reductions of up to 30% CO2 and 70% NOx during engine operations.

Global Workboat Segment Manager, Caterpillar Marine, Alexander Kohse, said: “As part of the new and growing offshore wind segment, Caterpillar is actively working with its to ensure customers receive support during the energy transition. Our strong presence in the offshore industry demonstrates our commitment to deliver optimum power and energy efficient solutions to our global customers.”

Edda Wind was formed in 2015 in Haugesund by the Østensjø Group. Five years later, the Wilhelmsen Group became a partner in the company.
