zoomCoast Guard crew members stand with 11 survivors of the Tug Nalani at Coast Guard Station Honolulu.

Eleven people are safe after a 95-foot towing vessel sank approximately two and half miles west of Barbers Point Harbor in Oahu on Thursday.

Watchstanders at the Coast Guard Sector Honolulu command center received a call at 3:13 p.m. from the pilot aboard the towing vessel Nalani stating their vessel was taking on water and they were in danger of sinking.

The Coast Guard Cutter Kittiwake, an 87-foot coastal patrol boat homeported in Honolulu launched to the scene along with a 45-foot Response Boat-Medium crew from Coast Guard Station Honolulu and an MH-65 Dolphin helicopter crew from Coast Guard Air Station Barbers Point.

The towing vessel Tiger 7 and a National Oceanic and Atmospheric Administration patrol boat also arrived on scene to assist.

The crew of the NOAA vessel safely rescued 9 crew members, and the Tiger 7 crew rescued 2. No injuries were reported.

The RBM arrived on scene shortly after the rescue and safely transferred all 11 survivors aboard and for transport back to Station Honolulu.

The Coast Guard is conducting an investigation into the sinking and has begun interviews with the crew. The cause of the sinking is unknown and is under investigation.

The Nalani sank in approximately 2,200 feet of water and was carrying an estimated 75,000 gallons of diesel fuel. An oil sheen was observed by Coast Guard responders before nightfall. Shoreline assessment teams will be out to evaluate shorelines for impact.

Identified areas of potential impact are from Barbers Point, north to Nanakuli.
