Shipping company Torm has reported that its oil and chemical tanker the Torm Mary struck bottom whilst leaving port on the Piscataqua River near the Irving Terminal, Texas, US.
The 528-foot oil tanker was pulled to a pier by tug boats sent out in response by the US coast guard.
Marine Safety Detachment Portsmouth Harbour has sent a marine casualty investigator and inspector and a pollution investigator to the tanker to determine the extent of the danger.
There were no reports of pollution.
Our biggest concern at this point is pollution, Lt. Dan Satterfield, officer in charge of the Marine Safety Detachment Portsmouth Harbour said. We will work with the tanker's crew to ensure the vessel is structurally sound before it leaves port.
