Finnish technology group Wartsila has denied its repairs were responsible for a fire in the engine room of a US tanker.

The company is being sued for negligence and breach of contract and warranty over a blaze on the 21,600-dwt molten-sulphur carrier Sulphur Enterprise (built 1994) near Galveston last May.

A suit filed at the southern district court in Texas by owner Savage SE Operations and its overseas underwriters alleges "significant and extensive damage" to three auxiliary engines and other parts of the engine room.
