ANCHORAGE - The state of Alaska has filed a lawsuit against the contractor responsible for the design and construction of the fast ferries Fairweather and Chenega.
The lawsuit also names the companies responsible for the propulsion system on the ferries.
Transportation officials say the propulsion systems have had recurring problems since the state took delivery in 2004 and 2005.
The Fairweather underwent a massive overhaul in 2006. The state says all four diesel engines had hairline cracks in their steel sleeves, among other problems.
The lawsuit was filed against Robert E. Derecktor Inc., the contractor. Also named are MTU Friedrichshafen, GmbH and MTU Detroit Deisel Inc., companies responsible for the propulsion systems.
Attempts to reach the companies for comment Friday were not immediately successful.
