The US flag tug/ tanker barge Scott Turecamo/ New Hampshire are anchored in the harbour waiting for a low pressure system to pass before heading south. This is the second trip to Halifax this month for the pair which are used to shuttle petroleum products.
Although the tug and barge are connected with an articulating pin system which can withstand most weather conditions, the barge's low freeboard forward must be a concern in bad weather. The pair are owned by Moran Towing, and are based in New York. The tug is 5,100bhp vessel and the barge has a capacity of 118,000 bbl.
