Following this order, Siem has 10 similar AHTS under construction at Kleven Verft and its sister Myklebust Verft and has an option for a further two.
The 91.0 m LOA x 22.0 m beam vessels are of Vik-Sandvik VS 491 CD design and will have 28,000 BHP installed horsepower, a bollard pull of 300 tons, winch of 500 tons, accommodations for 60 persons and full PSV capacities.
