This was my second rig as a medic with Sedco. The C unit as we called her was used as an accommodation unit in the frigg field in 1977, I'm sure thats where met Alfe Cooke. I was on tow to Algeciras in Spain where she was refitted and then we towed her to Nigeria. We had some good laughs and good times.
Unfortunately she was burned down after a blowout. She sat on bottom as the
location wasnt deep and you could see the bop sticking up from the sea floor

I was on Sea Quest back in 1971 I think it was, she was lying about 90 miles off Aberdeen, we had a near miss from a blow out then if I recall. I also seem to recollect she had a sister ship called Sea Gem that went down before my time. Can anyone confirm this?

Sea Gem sank in the north sea in the early days of the oil field development. Bristow Helicopters flew out to evacuate her as she was sinking, no lives were lost.

Sea Gem suffered structural failure on 27th Dec 1965. 13 workers died out of 32 on the platform.

Blow me away. I was hitch-hiking around Europe and landed a job on the 135C anchored in the Bay of Gibraltor on it's re-fit. I'll find some photos. I passed on the tow around which I still regret. One day there were signs - don't flush toilets. Well I was scrbbing floors and had to empty the bucket so dumped it down the toilet. 10 minutes later up cam some poor Spanish chap with shit allover him - he'd been painting the hull below the sewer outlet and I guess I just flushed the last mess out on him. He wasn't too happy.

I believe the 135c was the last oil rig built in my home-port of Victoria B.C. excessive labour costs etc.

With respect to Sea Gem check out 13 souls - what a shame.

Sea Quest and Sea Gem are entirely different exploration platforms.

Sea Quest was the exploration platform built by Harland and Wolfe which found the Arbroath and Forties Fields in 1969 and 1970 respectively. Wikipedia says the following about Sea Quest:In 1977, Sea Quest was sold to Sedco (now part of Transocean) and renamed Sedco 135C.[2][7] She was towed to the west coast of Africa. In 17 January 1980, while drilling in the Warri area, Nigeria, a blowout occurred and the rig get extensive fire damage. The rig was then deliberately sunk in deep water.

The Sea Gem was an earlier exploration platform which found the West Sole Field in the Southern North Sea in 1965. The structural failure, described above occurred when they were moving the platform a few days after BP announced the gas find.

I stand corrected. It was in fact the 135F which was built in Victoria at the VMD in 1967. It did a couple of holes off the West Coast of Vancouver Island, then to the S. Pacific with Shell New Zealand. With disappointing production she then went with Amoco to the North Sea. I'm no oil rig guy, I grew up in a small shipyard near Victoria and had just chanced upon the 135C - some of the stories I've encountered in 'surfing" oil pages are amazing.

I worked on the Sea Quest Feb 71- Sep 72 in the Forties Field, great rig for its time (bumper sub, spinning chain, no drill string compensator or top drive technology)still managed to drill a lot of wells in some fairly average weather.I have forgotten some of the guys names but the Tool Pusher was Tom McInlay, Driller John Smith AD P.K Oddy Derrickman Iain Thomson Pumpman George Pemberton It was a great crew as were the other guys onboard. I have worked on quite a few rigs since those days but I have to admit they were some of the best

I worked as a diver for Oceaneering in Nigeria. I was there when the blow out occurred. Two weeks or so later it caught fire. Red Adair had crews there but the geological formation collapsed and the fire went out. After that I was part of the diving crew that salvaged her.

I was on the SEDCO 135F and Larry Hearter or Harter really helped me get all the info to progress from the Roustabout stage spent time with Subsea Engineers, Welders, Mechanic, and the Rig Floor then Shakers, promoted to Roughneck, something happened to the Derrickman and they asked us Roughnecks for a volunteer to work Derrick none of the more experienced Roughnecks wanted to try so having worked on Roofs onshore I had no fear of Heights I managed to help out like a Duck to Water, and went to SEDCO School on my 1 week off 2 weeks on in them days, yes spinning chain and Bumper Subs but a good Apprenticeship, I would love to Thank Larry Hearter or his folks for all his help, I did see him many years later when I was a Casing Casing Crew Hauler for Salvesen Casing Crews, but looking back I can't remember If I sincerely thanked him, I worked Offshore to Assistant Driller Level 15 years and Saved my own and other people lives on a few occasions.

Yes I am still looking to thank Larry Hearter or Harter the Tool Pusher that gave me help to be a Roudtabout in story above looking back I wouldn’t have had that chance to become an experienced Hand 17 years away from home if anyone has an email address please advise
