“The ship has been ballasted to keep her upright and afloat. There are two pilots on board keeping port control informed of the situation and advising the ship’s master of local conditions,” it said in a statement.
The accident involving the diesel tanker MT Pacific Quartz happened at 3.15am on Friday.
“She damaged a ballast tank on the starboard [right] side just in front of the accommodation quarters and began to take [on] water,” it said.
“The MT Pacific Quartz was heading for Island View eight in swells of five to six metres and a wind speed of eight to ten knots when the incident happened.”
The SA Maritime Safety Authority was investigating.
“There is no risk of pollution as the vessel is a double hull tanker and all cargo tanks are intact, and the crew is unharmed.”
