CSM and Hydrus team up to switch from offshore wind support vessels to hybrid propulsion

CSM Energy, part of the Columbia Group, and Hydrus Engineering have entered into a partnership to assess and modernize Offshore Support Vessels (OSVs) working in the offshore wind industry to transform them into hybrid vessels powered by both battery and solar power. fuel.

“The offshore wind market is driven by the shift away from fossil fuels and as such the green profile of the stakeholders involved is essential”, noted Lambros Nakos, partner at Hydrus Engineering.

Demand for OSV is expected to increase with growing investment in offshore wind, after the market has seen an oversupply of vessels and declining oil requirements in recent years, according to the new partners.

Modernizing existing ships will be much faster and much more cost effective than building greener OSVs from scratch, CSM and Hydrus Engineering said in a joint statement.

“Building new ships with a substantial or even completely green profile will cost considerably and take several years before they are ready to be put into service”, noted Kyriakos Tsangaris, technical director at CSM Energy.

Lambros Nakos of Hydrus Engineering said the current order backlog of new OSVs has declined since 2016, with less than 50 vessels on order since the start of 2020. As existing offshore support vessels will be operational for another 25 years, their modernization is the best option. to make sure they are environmentally friendly.

CSM Energy and Hydrus plan to provide the full range of services aimed at making VSOs greener, including feasibility assessment, pre-financing assessment, budget and procurement control, engineering, modernization, supervision and monitoring. commissioning.

OSV suppliers in the offshore wind sector have stepped up their efforts to decarbonise existing vessels and therefore operations at offshore wind farms.

In May, Seacat Services reported that its Seacat Enterprise The vessel had completed its first operational missions at the Triton Knoll offshore wind farm using HVO30 hydrogenated vegetable oil (HVO) fuel.

The following month, ScottishPower Renewables launched a pilot project to reduce carbon emissions at the East Anglia ONE offshore wind farm by powering two Crew Transfer Vessels (CTVs) supplied by NR Marine Services with HVO30 fuel.
