03 July 2015, News Wires – A helicopter on its way to a drilling rig off the Canadian province of Newfoundland & Labrador was forced to turn back to shore due to a low-pressure warning in one of its engines.
The CHC-operated helicopter, a Sikorsky S-92 model, was about 20 kilometres off St John’s on its way to Seadrill semi-submersible West Hercules, which is drilling for Statoil on the Bay du Nord prospect in Flemish Pass, about 470 kilometres offshore.
Statoil notified the Canada-Newfoundland & Labrador Offshore Petroleum Board (C-NLOPB) that the helicopter returned to base on Tuesday “due to a low oil pressure indication in one of its two engines”.
“The helicopter returned to St John’s without incident and the seven passengers on board were briefed by the pilots,” the regulator said.
The culprit of the oil leak, according to Statoil, was likely a wrong-sized O-ring installed during maintenance.
CHC is investigating.
In May, a worker was injured after falling overboard from the West Hercules. Statoil and C-NLOPB are conducting separate investigations into that incident.
