The captain of the container ship MSC Jubilee IX in Seattle was arrested by the U.S. Coast Guard Investigative Service (CGIS) on suspicion of operating the vessel while intoxicated last week.

The 48-year-old took two chemical breath tests by Washington State Patrol, both of which registered a 0.25% blood alcohol content, court records show.

The captain of the MSC Jubilee IX completed a Breathalyzer test and was found to be “impaired more than six times the legal limit for commercial mariners,” the Coast Guard said.
