Brent Spar - Aftermath

Aftermath

Having moored the Brent Spar in Erfjord, Shell commissioned the independent Norwegian consultancy Det Norske Veritas (DNV) to conduct an audit of Spar's contents and investigate Greenpeace's allegations. Greenpeace admitted that its claims that the Spar contained 5500 tonnes of oil were inaccurate and apologized to Shell on 5 September. This pre-empted the publication of DNV's report, which endorsed Shell's initial estimates for many pollutants. Greenpeace noted that its opposition to the dumping had never been solely based on the presence or absence of oil, however, and that opposition to the disposal plan was part of a larger campaign opposing the dumping of all waste into the North Sea.

Shell received over 200 individual suggestions for what could be done with the Brent Spar. One of these came from the Stavanger Port Authority. They were planning a quay extension at Mekjarvik, to provide new Roll-On/Roll-Off ferry facilities. It was hoped that using slices of the Spar's hull would save both money and energy that would otherwise have been spent in new steel construction. The Spar was raised vertically in the water by building a lifting cradle, placed underneath the Spar and connected by cables to jacks on board heavy barges. Jacking the cables upwards raised the Spar so that its hull could be cut into 'rings' and slid onto a barge.

After cleaning, the rings were placed in the sea beside the existing quay at Mekjarvik and filled with ballast. The construction of the quay extension was completed by placing a concrete slab across the rings. The Spar's living quarters and operations module, were removed and scrapped onshore at a Norwegian landfill site.

While the Brent Spar was being dismantled, quantities of the endangered cold-water coral Lophelia pertusa were found growing on the legs of the platform . At the time this was considered unusual, although recent studies have shown this to be a common occurrence, with 13 of 14 North Sea oil rigs examined having L. pertusa colonies. The authors of the original work suggested that it may be better to leave the lower parts of such structures in place – a suggestion opposed by Greenpeace who compared it to " a car in a wood – moss would grow on it, and if I was lucky a bird may even nest in it. But this is not justification to fill our forests with disused cars".
