The Sea Empress oil spill occurred at the entrance to the Milford Haven Waterway in Pembrokeshire, Wales on February 15, 1996. The Sea Empress was en route to the Texaco oil refinery near Pembroke when she became grounded on mid-channel rocks at St. Ann's Head. Over the course of a week, she spilt 72,000 tons of crude oil and 480 tons of heavy fuel oil into the sea. The spill occurred within the Pembrokeshire Coast National Park – one of Europe's most important and sensitive wildlife and marine conservation areas. It was Britain's third largest oil spill and the twelfth largest in the world at the time. Sailing against the outgoing tide and in calm conditions, at 20:07 GMT the ship was pushed off course by the current and became grounded after hitting rocks in the middle of the channel. The collision punctured her starboard hull causing oil to pour out into the sea. Tugs from Milford Haven Port Authority were sent to the scene and attempted to pull the vessel free and re-float her. Efforts were also made to offload any remaining oil from the ship but weather conditions caused delays, resulting in more spilled oil. During the initial rescue attempts, she detached several times from the tugs and grounded repeatedly – each time slicing open new sections of her hull and releasing more oil. A full scale emergency plan was activated by the authorities. News of the grounding was first reported at 21:18 on the BBC's Nine O'Clock News – just over an hour after she ran aground. Over the next few days, efforts to pull the vessel from the rocks continued. Tugboats were drafted in from the ports of Dublin, Liverpool and Plymouth to assist with the salvage operation.
