The Ocean Ranger The Ocean Ranger was an offshore exploration oil drilling platform that sank in Canadian waters 315 kilometres southeast from St. John's Newfoundland, on the Grand Banks of Newfoundland on February 15, 1982, with 84 crewmembers onboard. The Ocean Ranger was the largest semi-submersible, offshore exploration, oil drilling platform of the day. Built in 1976 by Japan's Mitsubishi Heavy Industries, it operated off the coasts of Alaska, New Jersey, Ireland, and in November 1980 moved to the Grand Banks. Since it was so big it was considered to have the ability to drill in areas too dangerous for other rigs. The government thought it was unsinkable, so they felt that there was no need to train a crew very well. The disaster…show more content…
This has only been done only twice before. They did not succeed. Then the next problem was the hole in the ballast control room port, due to another large wave crashing into the rig. The port hole was only 30 feet above the water line and did not have its steel storm plate installed. Water rushed in, soaking the control panel and shorting out its analogue relays, causing the rig to list to about 10 degrees. The crew removed the relays, rinsed them in clean water to get the salt out, and dried them with a hairdryer. The control panel was still wet, after they inserted the relays, and shorted out again. The crew then tried to manually start the pumps to fix the rig, but this made things worse. There were no manuals on board explaining the ballast control system so they did what they felt was right. Instead of emptying the ballast tank on the side where the rig was listing, they pumped in more water, to try and start the pumps working but, this just increased the list to about 15 degrees. If the crew had used the knowledge of hydraulics pumps they would have realized that it would not be possible to to get rid of a leak by pumping in more liguid. Doing so would cause a large overflow destroying the pump. In the future, to avoid a problem like this engineers could have a back up system that would be able to pump out the liguid, one that could use the water as a power source. The engineers could
