Cargo ship near California pipeline made strange movements: report

A massive cargo ship made a series of unusual movements while anchored in the closest spot to a Southern California oil pipeline that ruptured and sent crude washing up on beaches, according to data collected by a marine navigation service.

The Coast Guard is investigating whether a ship anchor might have snagged and bent the pipeline owned by Amplify Energy, a Houston-based company that operates three offshore oil platforms south of Los Angeles.
