Sweden-based CTV owner and operator Northern Offshore Services (N-O-S) has ordered eight more crew transfer vessels.

Northern Offshore Services has signed one of the largest Crew Transfer Vessel (CTV) orders in history.

N-O-S already has four vessels on the way, ordered in late September last year. With the new order, the E-class series orderbook has reached 12 vessels.

First of these vessels, the Explorer, will arrive in Europe as soon as next week. The agreement includes several options for additional orders.

The new 36-meter E-class vessels are designed to have a large cargo capacity tailored to future offshore wind demands, a future-proof platform supporting the transition to electric and alternative fuels, and an improved hull design and advanced automation system to optimise energy efficiency.

“The market is evolving fast, but we are faster, and we always try to be one step ahead. With this investment, we ensure a diverse and capable fleet profile, setting a new benchmark in our segment,” says David Kristensson, group CEO of Northern Offshore Services.
