Cleanup of a 1,000-gallon diesel fuel spill in the Columbia River was completed on Monday, four days after the incident in which a bulk carrier collided with a pier in the Port of Astoria, Oregon.
But investigations continue into why the incident happened.
On Friday the 565-foot Panama-flagged Global Gold (33,562 dwt, built 2012), which was on its way to pick up a load of timber at Astoria, suffered a four-foot gash to its hull in the collision, which caused the spill into the Columbia River.
US Coast Guard (USCG) and other state and federal agencies combined in the containment and cleanup operation.
A hard boom around the ship and the pier was removed on Saturday and an absorbent boom was taken away on Sunday.
Global Gold cannot load its cargo or leave the port until USCG is satisfied with repair work done to the collision damage.
