Worley helps Allseas to decommission two offshore gas platforms We worked with customers and the government to provide an abandonment plan for the Brent Delta AllSeas in the UK North Sea. This large offshore facility included a 500km pipeline.​ Our teams delivered environmental risk and impact activities and a decommissioning plan. We made sure that standards and legal frameworks were adhered to in our environmental and technical reviews.​ Worley is also supporting Allseas with a range of decommissioning engineering, procurement and construction services for Allseas’ DP3 and DP4 project in the eastern Irish Sea. This includes engineering preparations to safely remove two of Spirit Energy’s 11,000-tonne platforms, DP3 and DP4, at Morecambe Bay.​ Worley has been supporting Allseas, a world-renowned offshore contractor, since early 2020. This includes engineering preparations to safely remove two of Spirit Energy’s 11,000-tonne platforms, DP3 and DP4, at Morecambe Bay.
