How This Monster Wave Killed 84 Men: Ocean Ranger Tragedy

How This Monster Wave Killed 84 Men: Ocean Ranger Tragedy This is the full story of the 1982 Ocean Ranger oil rig catastrophe. This episode is about the tragic sinking of the semi-submersible oil rig Ocean Ranger and its crew on February 15, 1982, off the Canadian coast of Newfoundland and Labrador. The "unsinkable" Ocean Ranger oil rig was brought down by human hypocrisy and stupidity. With 84 crew members on board, it sank while drilling an exploration well for Mobil Oil of Canada, Ltd. (MOCAN) on the Grand Banks of Newfoundland, 267 kilometres (166 miles) east of St. John's, Newfoundland. Which left no survivors. Ocean Ranger was designed and is owned by the New Orleans-based Ocean Drilling and Exploration Company, Inc. (ODECO). A sizable self-propelled semi-submersible, the ship had residential quarters and a drilling facility. It was able to drill down to a maximum depth of 25,000 feet (7,600 m) while operating beneath ocean water that was 1,500 feet (460 meters) deep. It is the biggest semi-submersible oil rig in the world as of right now, claims ODECO. At 396 feet (121 meters) long, 262 feet (80 meters) broad, and 337 feet (103 meters) high, Ocean Ranger was a ship built in 1976 by Mitsubishi Heavy Industries in Hiroshima, Japan, for ODECO. There were 12 anchors on it, each weighing 20,000 kilograms (45 000 pounds). 25,000 tons made up the weight. Two 400-foot (120-meter) pontoons supported it as it floated. The ship was designed to endure rough seas, such as winds of 100 knots (190 km/h) and waves of 110 feet (34 m) high. It was licensed for "unrestricted ocean operations." Before moving to the Grand Banks region in November 1980, it had been active off the shores of Ireland, New Jersey, and Alaska in the past. On November 26, 1981, Ocean Ranger began drilling well J-34, the third well it had planned to drill in the Hibernia Oil Field. Sedco 706, 8.5 miles (13.7 km) north of Ocean Ranger, and Zapata Ugland, 19.2 miles (30.9 km) north were two other semi-submersible platforms that were drilling nearby. Reports of an approaching storm connected to a significant Atlantic cyclone reached the platforms on February 14, 1982. Typically, disconnecting the riser from the subsea blowout preventer and hanging off the drill pipe at the underwater wellhead were required to prepare for severe weather conditions. Due to surface challenges and the speed at which the storm developed, the crew of the Ocean Ranger was compelled to shear the drill pipe after hanging off. They removed the riser in the early evening. A big rogue wave struck the adjacent Sedco 706 at around 19:00 local time, damaging some things on deck and resulting in the loss of a life raft. Soon after, radio communications from Ocean Ranger could be heard discussing the best ways to fix the damage while noting a broken portlight (a porthole window) and water in the ballast control room. The unprotected portlight, which is 28 feet (8.5 m) above the water line and exposed to wave damage, was reported by Ocean Ranger to be experiencing storm seas of 55 feet (17 m) with the occasional wave reaching 65 feet (20 m). The Ocean Ranger's ballast control panel valves looked to be opening and closing on their own accord, according to radio talks that started on Sedco 706 and Zapata Ugland shortly after 21:00. The radio exchanges also covered the seas up to 65 feet (20 meters) high and winds up to 100 knots (190 km/h). The rest of the evening was spent in typical radio communication between Ocean Ranger, nearby oil rigs, and each of their various support vessels. There were no unusual occurrences found. Observing a serious list to the port side of the rig and calling for quick help at 00:52 local time on February 15th, Ocean Ranger sent out a Mayday call. For the first time, Ocean Ranger identified a serious issue in this communication. #naturaldisaster #naturaldisasterscaughtoncamera #naturaldisaster #ridddle #theuntoldstory #titansubmarine #titansubmersible Disclaimer Fair Use: 1.
