Environmental campaigners are calling for urgent action after a laden floating storage and offloading vessel developed a list off Venezuela.
The 208,000-dwt Nabarima (built 2005) has 1.3m barrels of crude on board and hit the headlines last month when three metres of water was pictured inside the vessel.
Gary Aboud, corporate secretary of Trinidadian environmental group Fishermen and Friends of the Sea, went out in a small boat to inspect the vessel on 16 October.
