Bourbon Offshore Norway orders X-bow PSV's

Groupe Bourbon member Bourbon Offshore Norway, has signed a contract with Ulstein Verft for the construction of two Ulstein PX105's.

They will be the world's first platform supply vessels (PSV's) with the Ulstein X-bow. Earlier this year the shipowner contracted the first anchor handling vessel with this type of bow.

"When we signed the contract for an Ulstein AX104 anchor handling vessel in April, it was because we had great faith in the new hull shape," says Trond Myklebust, managing director of Bourbon Offshore Norway. "The extremely good results from the model tests for the anchor handling vessel convinced us that the Ulstein X-bow is the way ahead for offshore vessels"

"We think there is even more to be gained from a PSV with this new bow," adds Myklebust, "as these types of vessels are continuously in traffic. They work in a shuttle system between land and the platforms and have to be reliable also in bad weather. The seaworthiness with the Ulstein X-bow is so good that a vessel could be in operation even when the weather means other vessels have to stay in port. Fuel consumption is also reduced."

Ulstein Verft sales manager, Harald Moeller, also stresses the PX105's operational reliability.

"Low angles of entry, no bulb, a converted bow and a hull that is drawn right up to the wheel house mean that there is no slamming or spray on deck," says Moeller. "The good seaworthiness will make the vessel a fantastic place to work."


Myklebust says: "This vessel is the first offshore vessel in the world that satisfies the CLEAN DESIGN class requirements and is also fitted with diesel electric propulsion. Strict environmental requirements have to be met to achieve this classification. Among other things tanks containing oil products must not border the sides or bottom of the vessel and the gas discharge restrictions are stricter. In addition to this there are options for oil recovery operations (ORO) and catalyzers for exhaust gases from the engine units. We have long focused on the environment when it comes to our vessels, and want to be at the cutting edge in this development."

The vessels will also be prepared for operations in northern areas.


Ulstein Verft currently has a busy delivery schedule with deliveries of new vessels every second to third month. The two ULSTEIN PX105s will be delivered in October 2006 and February 2007.

With these two new contracts, Bourbon Offshore Norway has now ordered six vessels from Ulstein Verft worth a total of around NOK 1.5 billion (US $225 million) in less than ten months.

"There is a great deal of optimism and activity in the North Sea," notes Moeller. "New oil fields are being investigated and more test wells are being drilled. Ulstein Verft is also benefiting from this optimism. We have a reputation as a deliverer of quality vessels, and we manage to deliver on time according to contract. We also have healthy finances. A good reputation is important when it comes to hauling in build contracts," says Harald M¿ller.
