It was the evening of February 14, 1982, a night that began like many others on the Grand Banks of Newfoundland—cold, dark, and unforgiving. The Ocean Ranger, the world's largest semi-submersible drilling rig, stood sentinel over the icy waters of the North Atlantic, towering above the endless, restless sea. Its mission: to probe the depths of the Hibernia oil field, a promising frontier in offshore exploration. Built to withstand the ocean's wrath, the rig was believed to be unsinkable, a fortress of steel amidst nature's wild unpredictability.
