Shell Canada asks regulator to leave huge pipe on sea floor off Nova Scotia

Shell Canada has officially applied to abandon two kilometres of pipe it accidentally dropped on the ocean floor off the coast of Nova Scotia. The pipe, known in the industry as a riser, broke free from a surface ship March 5 during a winter storm. “Because of the unacceptable risk associated with the health and safety exposure and potential impact to human health of offshore workers, Shell does not perceive recovery of the riser … as a viable response option,” Shell Canada’s exploration manager said Friday in a letter to Canada-Nova Scotia Offshore Petroleum Board. “Considering the health and safety exposure associated with recovery, the minimal impact to other ocean users, as well as the lack of significant adverse environmental effects, leaving the riser … in place on the seabed is Shell’s safest and most appropriate response option.”  Read the story here 09:54
