Sedco Express

Sedco Express

DP3 Drilling Rig - 'Sedco Express'.

A novel design whereby the six Diesel generators are located in the pontoons, the 'Well Construction Centre' (derrick assembly) consists of three derricks to allow simultaneous assembly and drilling operation, and the WCC is located at the aft end of the rig, which allows the BOP, stack, slipjoints etc to be lifted from supply vessel/barge using the travelling block.

Photo taken as SE was arriving on location to commence drilling Leviathon field off Israel.

These were a radical design at the time Al and one of the things you mention, lifting BOP etc from the boat did away with the need for a heavy crane on the after end. A crane that normally did very little work anyway. I think the Express and her sisters were some of the first 10.000 foot water depth rigs.

Yeah Don - I think they are still fairly unique (Energy and Express). They have pretty fast mobilisation time, and can fairly throw the riser/pipe down the hole. Having all engines and (4) winches down in the pontoons take a bit of getting used to - but gives far more space up top.

You guys would just not recognise a modern rig, jack up or semi, compared to the 135 type rigs. Night and day in every respect. Rigfloors are now more like the Starship Enterprise than 135. Trying to make it easier on the boys and faster on the rig. Accomadation worlds apart making it better for the catering crews as well.

The assembly of the riser pipe must take a bit of doing, is it flanged or screwed?

You would have to call it 'socketed' with locking lugs

Calvin - I just looked up the Sedco 135F and it seems that it was the rig which caused the previous 'catastrophic' oil spill in the Mexican Gulf in 1979. It was that spill which was being held up in US media recently - as being proof that the likes of BP had learned nothing. What the media failed to acknowledge was the fact that today - there is no evidence of that spill in the Gulf environment.

Al Once the American government noticed that people were blaming Obama big time for not doing more, they went right after BP and still do despite the information coming out which blames Transocean and Halliburton. They dont want to exept that the US had anything to do with it,especially a company owned by one of their own senators so they keep trying to blame BP for everything.
