World Marine Offshore and the Windfarm Industry

The offshore wind market is rapidly evolving. The European countries continue to lead the way with continuously increasing number of wind parks and locations further and further offshore requiring effective and specialized solutions.

CTV (Crew Transfer Vessel) is a generic term in Offshore Wind to illustrate fast vessels with main purpose of transferring crew/technicians from shore to offshore installations. A similar type of vessel is the crew boat/FSIV (Fast Support Intervention Vessels) known from the Oil and Gas industry.

The CTV industry emerged together with the first offshore windfarms in Northern Europe but is spreading quickly with installation of offshore wind turbine generators (WTGs) in Asia and soon in the US.

Over the last 10 years, we have witnessed that offshore wind is gaining further momentum both politically as well as technologically when compared to onshore wind. This is largely due to NIMBY (not in my backyard) opposition groups gaining support locally as well as the decreasing overall project cost difference.

Back in 2010, World Marine Offshore saw a business opportunity to provide a custom-made specialized vessel design to service the offshore wind market. The wish to meet and exceed the clients’ needs resulted in a unique design with the market’s first trimaran CTV with space for 24 passengers.

World Marine Offshore and Crew Transfer Vessels

The initial Crew Transfer Vessel market was defined by a limited number of small monohull vessels from 8-15 m. They were typically serving a smaller amount of wind turbine generators of 2.5 to 6 MW.

As turbine size continuously increased to what is considered standard today, 9.5 MW, operators and developers required new and improved methods resulting in new technology, higher speed and improved turbine accessibility.

In order to meet these requirements, the next generation of vessels became the much improved catamaran and SWATH designs that improved accessibility significantly when compared to monohulls.

The business opportunity WMO saw in 2010, was the need for a vessel design that would enable the charterer to carry out all standard tasks but in addition, the vessel should be able to remain offshore. Thereby it was possible to avoid transit time to and from port every day, eliminate cost and time for accommodation for marine crew but most importantly, there was a need for higher accessibility to increase working hours for pax.

WMO’s choice was the aluminium Trimaran SWATH design. On speculation, the company ordered two large 30m versions and four 25m vessels to kick off the business from its headquarter in Esbjerg, Denmark.

Since the start of the company, WMO continue to grow and expand its fleet and scope of services worldwide.
