Siem adds to AHTS orders at Kleven
Norway's Siem Offshore has declared an option for the construction of two additional large Anchor Handling Tug Supply vessels (AHTS) at Kleven Verft AS. The contract value is approximately NOK 1.1 billion (about $185 million), and the vessels are scheduled for delivery in first and second quarter 2010.
The 28,000 bhp vessels which are of Vik-Sandvik VS 491 CD design will have a bollard pull of 300 tons, winch of 500 tons, accommodation for 60 persons, full PSV capacities and are designed with a special focus on safe anchor handling operations.
The vessels are 91.0 m in length over all, with a beam of 22.0 m.
The engine configuration will enable both diesel mechanical and diesel electric propulsion which, in combination with the hull design, will represent efficient fuel consumption and reduced emission.
Siem Offshore already has 6 identical vessels under construction at Kleven Verft and its sister Myklebust Verft
