Hibernia oilfield operators are facing a significant fine of almost $500,000 due to an oil spill over four years ago. Hibernia Management Development Company (HMDC), responsible for overseeing operations at the oilfield, initially attributed the spill to a malfunctioning sensor, which monitors oil and water levels in storage cells. However, in a recent court session, Hibernia changed its stance and pleaded guilty to a single charge linked directly to the oil spill. In addition to this spill, Hibernia faced another incident involving nearly 2,200 liters of oil just one month after the accident. This penalty highlights the importance of adhering to safety protocols and environmental regulations in the oil and gas industry.
