Wartsila to Provide Propulsion Packages for 3 Offshore Support Vessels

Wartsila has received a propulsion packages order from Sealion Shipping, the UK-based operator and manager of the Toisa fleet in September. The units are to be installed in a series of three Multi-Purpose Subsea and ROV Offshore Support Vessels (OSV), to be built at the ABG Shipyard in India.

The OSVs will be of Vik-Sandvik design, and for each vessel Wartsila will supply a propulsion package, which include diesel-electric propulsion system based on four 6-cylinder in-line Wartsila 26 main generating sets. As part of the approximately EUR 30 million contract, Wartsila will also supply six thrusters and a complete automation and electrical distribution package based on its Low Loss Concept, to each of these DP2-class vessels.

According to Sealion Shipping's Newbuilding Manager Ray Crosby, the Wartsila diesel-electric propulsion configuration was selected in order to enable a greater degree of flexibility for Remotely Operated Vehicle operations of the ships.

"New vessels are needed to meet the higher demands in safety, dynamic positioning, and environmental standards. Wartsila has proven its ability to support owners and ship builders in solving the various technical problems associated with new construction," Crosby added.

Toisa currently operates seven Multi-Purpose Offshore Support Vessels (OSV) within its modern fleet of 24 various OSVs. In addition, the company has a further twelve vessels under construction, which will enter service in the near future.

Sealion Has 60 Wartsila Engines in Operation

Sealion Shipping, the manager of Toisa fleet, trading in the North Sea, the Gulf of Mexico, offshore Brazil and in Southeast Asian waters, is a valued customer of Wartsila, with more than 60 Wartsila medium-speed engines in operation.

"Sealion ordered its first Vik-Sandvik design VS 483 vessel in 1997 and since then has ordered several upgraded versions of the same design. Wartsila has supplied these vessels with its engines, reduction gears, and controllable pitch propellers. The Mk4 design is the latest modification and incorporates a diesel-electric propulsion arrangement. We have worked very closely with Sealion to develop the new design and to find the optimum propulsion solution in each case," said Paul Bennett, Ship Power Sales, Wartsila in the UK.

Vik-Sandvik was acquired by Wartsila in July 2008. This acquisition was a major step in Wartsila's strategy to strengthen its position as a total solutions provider.
