Video: Incredible time-lapse footage shows Clair Ridge topside installation

This short clip shows the topside being installed on BP's £4.5million North Sea Clair Ridge project. The footage comes after the oil major revealed three huge topside modules had been installed on the "quarters and utilties" (QU) platform following their long journey from a shipyard in South Korea. BP and its project partners - ConocoPhillips, Chevron and Shell - aim to produce 640million barrels of oil over 40 years from the field.
