About 1510 local time on January 22, 2015, the uninspected towing vessel Nalani began taking on water and sank in 2,200 feet of water while conducting sea trials off the southwest coast of Oahu, Hawaii. All 11 persons on board were rescued after abandoning the vessel. No one was injured. An oil sheen was observed by responders and crewmembers. The vessel was not salvaged due to the water depth and was declared a total constructive loss.
