The Coast Guard has wrapped up its investigation of the M/V Bangkok Bridge, an 874-foot cargo ship that lost engine power in Unimak Pass this winter. They've levied a $75,000 fine against the ship's owner, K-Line, for failing to report a hazardous condition.

Federal law states that you have to notify authorities in the event of a central engine failure. The Coast Guard investigation found that the Bangkok Bridge made no attempt to do that.

Unalaska’s Coast Guard detachment had to contact the vessel as it drifted on the edge of the eastern shipping lane, and ask if it needed assistance. The crew was able to refire the engines and make it to Summer Bay, where they anchored and completed repairs.

The Bangkok Bridge is a relatively new vessel; it was built in 2010.
