Kleven Maritime books its largest order ever

Kleven Verft in Ulsteinvik, Norway, has, in cooperation with its associated company Myklebust Verft, signed contracts with Siem Offshore Inc in Kristiansand, Norway, for the building and delivery of six large and environmental friendly anchor handling vessels of Vik Sandvik VS 491 CD AHTS design.

The contracts include options for delivery of a further six similar vessels.

The vessels are sophisticated anchor handling vessels with supply vessel capacities (AHTS) named VS 491 CD AHTS, designed by the Norwegian design company Vik Sandvik. The contractual value for the 6 first vessels is NOK 3.2 billion (US$ 478 million), making it the largest single order in the history of Kleven Maritime.

The vessels will be 91,0 meters of length, with a beam of 22,0 meters. Total engine power will be 19.000 kW (28.000 bhp), winch capacity will be 500 tonnes. Bollard pull is calculated at 300 tonnes.

The combination of environmental friendly design and large capacity makes these vessels especially well suited for operations in the North Sea. The accommodation holds 60 persons. The vessels hulls will be reinforced to work in icy conditions, and furthermore be prepared for Aframe and ROV garage.

Siem Offshore says that the machinery will be configured for both diesel mechanical and diesel electric propulsion which, in combination with the hull design, will represent efficient fuel consumption and reduced emission.

Delivery will be from May 2009 until March 2010, optional vessels will be delivered in 2010.

Siem Offshore already has four contracts for deliveries at Kleven Verft.

In total the two Kleven Maritime shipyards now have orders for 27 vessels at a contract value of NOK 8.5 billion (US$ 1.27 billion).
