- In this deep dive video we look in detail at the specifications of the Transocean 'Deepwater Champion' drillship.
Our drilling expert Colin Higgins takes us through many aspects of this technical feat of engineering.
From moon pools to mud pumps, cranes to compensators, top-drive to transit speed, we cover it all!
Our thanks go to Colin for his time and insight!
Get in touch today to find out more about our TROVE databases - we'd be happy to arrange a demo:

The knowledge and experience of the contributors to this videos is incredible. Thanks for Sharing.
Glad you enjoyed it! Thanks for your continued support Mr Paul. I think my dumb questions and Colin's knowledge make a great combo. Best wishes, Mike
The advances in off-shore exploration and development are nothing short of amazing. The technology rivals the space program in complexity and expense, and the difficulty is possibly greater in off-shore than in space. Everything off-shore deeper than about 100 meters must be done remotely, with ROV equipment. Rigs have to be able to maintain position without anchoring.
But 3/4's of the world is covered in water, and we have already extracted most of the resources under land. So off-shore is the future of oil and gas extraction. Hydraulic fracturing is a limited method, which is running into trouble because of the amount of water that is destroyed in making the fraking fluids. Fossil fuels will be needed for many years to come, and they will continue to be extremely expensive.
Agreed Scott. Thanks for your comments
Great! good experience sharing! nice, thanks alot🎉🎉🎉❤❤❤❤
Glad you enjoyed it! Thanks for your support. We hope to do more videos like this at some point in the future.
i was a driller for noble when we built 4 6th drillships in HHI. what an amazing equipment they built. can't even imagine what a gen 8 ship can do
That's an idea for a future video. Any of the drilling companies want to help supply a script and also advertise their hardware at the same time? Please get in touch at info@1stsom.com
What is really mind-boggling, is when you are on the rig floor, trying to convince yourself that it is NOT the drill[pipe moving up and down with each heave, but it is the rig itself that is moving, and that the motion compensator is only taking out so much of the movement.
Agreed. So much of the technology of offshore installations is mind boggling IMHO!
One other thing about the "accommendations", I remember back in the late 1980's when I went out on one of ODECO's old (even then) semi's operating in the British sector of the North Sea, and the room for the service hands had TWELVE bunks, and later on, I was put in a NINE man 'room' on a platform rig in the GOM. Possibly the worst I ever 'lived' on was an accommendation barge for "the puking dog', an Italian oil company offshore the Republic of Congo, West Africa.
Sounds awful. 12!! Can't have had much sleep with all the combined snoring!
Great video! A lot of work must've gone into that one, thanks!
Some really impressive engineering goes into these.
Glad you enjoyed it! Thanks Dyer Straights for your continued support. These videos on explaining how drilling happens are proving to be popular - we will do more.
You must have thought of it but please can we have a video of how the wells get connected, gas processed etc. Would love to see exactly how the pipe from the rig to the well is connected & how a christmas tree works. Appreciate the content btw.
Great suggestion! We will look for an expert in this field to help make the video - watch this space
Impressive. I have worked on a DW drillship but there are many interesting facts that I was unaware until I watched this video!
Glad it was helpful! Colin Higgins has a wealth of experience and we look forward to more input from him.
Great video! Short but at rhe same time detailed overview was done for beginning drillers! A request from my side, could you have make a video how two first well section usually drilled? Everyone knows that first section is about to drilled with no return mud or preferably sea water on the rig but on the sea floor. As well question how connect Low Pressure Well Head Housing (LPWHH) and ythen for the secind well section HPWHH where first "H" means High. Thank you in advance!
Colin is now back in Perth Australia. He is now consulting for a company who specialise in top hole drilling solutions. I have no doubt we will get to this subject before too long. Thanks for your suggestions.
I may be mistaken, but isn't the 907 metric tonnes rating of the top drive, its maximum hanging weight, and the maximum rotating torque of 65,000 pound feet.
I can't help with that one Cementer7665 and Colin is travelling just now. We will try and answer this when Colin is back in Perth Australia.........
As the lead mechanical engineer on the DW Champion in HHI I can confirm that is correct.
so you have the drill pipe, and you said the mud flows back up the annular. what stops the the mud flowing back up the drill hole and eroding the entire hole out? is the drill pipe always protected from an outside casing down the hole? just the mud cake protecting the hole from collapsing?
We'll try and do a future video to explain further. Pumping mud down the drill pipe stops it flowing back up. Also the hydrostatic head keeps the pressure in the hole higher than in the formation. Casing is set at various depths. At times the drill pipe is in "open hole" with no outside casing. Hope this helps.
23:34 still waiting for the video about drilling mud systems.......... Please 🙏🙏🙏
We have so many topics to cover and so little time to put these videos together. Maybe a mud company could send us some slides?!?
@@TROVE-1stSubsurface I thought your friend who had a lot of knowledge and lore over drilling and completion operations would make a video with you like you both had made this video.
I can send some slides about drilling mud systems, solids control, waste management but they are just silent material and nothing more…
And I’m sorry if my request over mud systems found you worried about it🙏
Anyway you’re doing your stuff very good and I try to watch each video.
Those were childrens toy power figures. 4,3mW, it is less than a LED chip. On the other hand if it would have been 8,7 MW I would believe you. Those pesky SI units.
An excellent video which is becoming more relevant as the industry goes after harder to get wells.
Thanks Erbterb. I think there is much confusion which is endemic in the oil & gas industry. "m" is often taken to be 1000 and "mm" is a million. But sometimes "M" is used as a million. In SI units mW is indeed 1/1000th of a Watt and MW is one million Watts. We would be better off using "k" as per the metric system for 1000. I note you write 4,3 - we prefer 4.3 which probably indicates where you are from. Why humankind can't simply agree to use the same system everywhere to avoid confusion never ceases to amaze me. However, in this case, mea Culpa!
@@TROVE-1stSubsurface I fight tooth and nail for the comma convention. Commas for decimals and the other for thousands. Our universities here in sweden have started creeping into the anglo saxonism, while our young still learn what I learned.
Do you have information how much heating power is needed for an average heavy oil steam flooding project? There are old chevron videos that are useless and everything else is behind pay walls. I refuse to pay 15 USD just to find the scientific article was not relevant.
Can you please do a video on melbana energy? Cheers
Please help me here - what's the story in your opinion? We will make videos if there is a lot of interest. Why would this subject be a popular video do you think?
