The Coast Guard, Department of Health and responsible party Unified Command transitioned from response operations to an ongoing monitoring and response readiness posture, after the Nalani, a 95-foot towing vessel sank off Barbers Point Harbor, Oahu.
The ship with 75,000 gallons of diesel fuel sank on Thursday in 2,200 feet of water.
Shoreline and near-shore assessments indicate no sheening or smell of diesel, Coast Guard reports.
At the location of the sinking there was a very light sheen coming to the surface and also drifting south that is not recoverable and was dispersing quickly. Resources are ready to respond and attempt to recover product from the water in the event a recoverable amount appears.
No oiled wildlife has been reported.
