The supplier Mariner Sea was the last ship to sail from Halifax in 2010. She arrived in Halifax on December 12 (in photo above) and fitted out for some specialized cable work, and returned to port December 26. Since then she has unshipped the cable gear, and this afternoon moved to Imperial Oil to take bunkers.
This evening she set sail for the port of Nuuk, Greeland.
