A piece of offshore drilling equipment broke off a Stena Drilling drillship in waters near Nova Scotia, CBC reported on Monday.
Shell Canada said that the incident on Stena Icemax had happened at the Cheshire well on Saturday in severe weather.
The drillship had been moved away from the well in anticipation of rough conditions when high waves caused the riser and lower marine riser package – which connect the rig to the well during drilling – to fall to the ocean floor.
Shell Canada said no crew members were injured in the incident. It also said no drilling fluid was released into the sea and there was no damage to the blowout preventer.
Operations at the well have been suspended.
The well, in the Shelburne Basin deep-water exploration project, is about 140 miles offshore from Nova Scotia, one of Canada’s three Maritime Provinces along with Prince Edward Island and New Brunswick.
