Suncor probes ‘potentially fatal’ incident on FPSO

Canadian operator flags up ‘near miss with potential for fatality’ on Terra Nova field last month

Canada’s Suncor Energy is investigating an incident involving a worker on board a floater off the country’s east coast late last month that had the potential for fatal consequences.

The incident occurred on the Terra Nova floating production, storage and offloading vessel on the eponymous oilfield off Newfoundland on 24 June, provincial regulator Canada-Newfoundland & Labrador Offshore Petroleum Board (CNLOPB) said.

A worked on the FPSO was exposed to hazardous contents – hydrogen sulfide and benzene – in the unit’s slop tank.

“Immediately after the incident, the slop tank work scope was stopped and a health assessment of the worker was completed for potential exposure of harmful substances from the slops system,” CNLOPB said in Tuesday’s incident disclosure.

“Following medical assessment, the worker was cleared for regular duties and no treatment was required. The incident was initially classified as a Near Miss (Leak of Hazardous Substance).”

However, CNLOPB added: “After further investigation by Suncor Energy, it has been determined that due to the potential concentrations of hydrogen sulfide inside the slop tank, the incident has been re-classified as a Near Miss with Potential for Fatality.”

CNLOPB said it is monitoring Suncor’s continued investigation and follow-up response.
