Summary
BSEE investigates oil pollution from Thunder Hawk’s produced-water discharge following repeated production shutdowns and restarts. The report examines chemical dosing, separation and potentially inaccurate level sensing. It identifies inadequate management of change as the probable cause and discusses start-up sequencing, continued operation during pollution and reporting shortcomings.
