I've worked in ENSCO of Brazil in ENSCO 8500 and ENSCO 6004 for 2 years, the best company that i've worked ever... NICE PULLING RISER OPERATION... Ensco always the best.
Forgive my lack of technical terms and names for the parts, but the part that lifts the riser ( what we see being disconnected from 5:40 and connected to the next riser at 6:00) how is that secured? Is it by vacuum? I can't see any fasteners but I do see a couple of air lines connected/disconnected between the process?
+Jonay. Normally the deep water riser is connected to other joints of riser by 8 bolts of roughly 2 1/2" diameter. These are torqued by hydraulic torque wrenches to about 1000 ft/lbs of torque. However, when lifting or lowering riser and the BOP. Each new joint is lifted or lowered using a lifting nubbin. This is the part you see being disconnected from the joint being laid out, and reattached to the next joint to be laid out. This is secured in place ready for the lift, by a hydraulically activated locking ring. The locking rig is activated by about 3000 psi of hydraulic power, then the hoses are disconnected so trapping the activation pressure. The load being lifted can be up to 1000 tons.
+robert west Thanks for that, it was puzzling me, but yes a hydraulic action would be more sensible than vaccum (I don't know what I was thinking!). I see this equipment going in and out from the docks all day (work at the quayside doing the logisitcs for the vessels coming and going offshore) but piecing all the parts together interests me, your videos are a great help!
@@rfw700Sorry to bump the old thread. To clarify a bit, the lifting nub can grip the riser by giving it hydraulic pressure up to 3000 psi and loose the grip by using torque to release the hydraulic pressure. Is my understanding correct?
ok...I understand the bolts and flange connection...but how do the umbilicals connect? some sort of slip joint? I don't see anyone working on them...they provide electric and hydraulic power, right?
is the white fixture a spider? it holds the riser joint while the next one is going to be pulled. but i am curious as i have not seen a spider in that shape before.
+Dakshin Sudarshan perhaps different legacy brands under NOV. this should be Varco's. most of the recent drillships built in South Korea have Hydralift legacy.
+Dakshin Sudarshan That's a typical hydraulically activated spider as used on deep water semi's and drillships. Below the spider, there will sit a gimbal which will allow the supported string of riser to remain vertical, while the drillship or semi, continues to pitch and roll. On shallow water semi's and drillships they more normally consist of 4 manually activated drop down dogs, which sit underneath the flange of each riser joint.

Good to see an mechanical grab in action on this Rig but in this day and age is there any reason brute human labour should be the resource and should it have any place handling equipment like this?
Excelente trabalho! Mas com a tecnologia do ROBO SPIDER, desenvolvido pela empresa americana TORQ LITE, esse trabalho seria muito mais rápido, seguro e com menos pessoas envolvidas.
The riser is the piece of pipe between the wellhead/BOP stack on the sea floor and the drill ship/platform. it forms a conduit for drilling mud and pressure control around the drill string.
Rick Fountain what? The riser is a drill bit? That's is not its purpose not even close. Hopefully I missed a comment or something because you could not be that stupid.
You would be wrong. Offshore workers are not in a union and it is very tough work. On your feet for 12 hours a day, for at least 2 weeks straight. Dangerous but rewarding for those taking the risk. No degree required.
Bad ass. Every tone I fill up my car I will remember this.

Great job guys.nice communication good team work ✌👌👌👌❤
Thank a rig worker for your petroleum products you use every day!

It’s a hydraulic clamp

I kinda want to get back out there. Miss that oil field life.
WOW! I have done some rod trippin in my days, but that gear is gargantuan
The pulling Mariner Riser
I thought this might’ve been a Maersk rig
I can't believe how cheap gas is when I see how much work it is just to get it out of the ground.
Miss those days!
But, but, where’s the hammer wrenches??🤣🤣

that is the spider. they look different on drillships.
this was Ensco 8502

Hi gays, say me international company sabsea and surface please. I have experience .
Ensco 8500 series semis?
Ensco 8502 to be exact.
+Dylan Sauce i see. thanks for the verification. i heard they are some of the most outstanding rigs so far. good stuff.
Yeah we did a lot of work.
God damn those bales are fucking huge
So its true. Oil rig riser are massive, so the TUNA also.
Between 54 and 72 inch outside diameter is common for the neutrally bouyant risers (which these appear to be)
what is that platform you working on ?
this is Ensco 8502
OK but wtf is it and why are you changing it???
The riser is the piece of pipe between the wellhead/BOP stack on the sea floor and the drill ship/platform. it forms a conduit for drilling mud and pressure control around the drill string.
Simply put...its a long fucking drill bit...
Thanks.
Rick Fountain what? The riser is a drill bit? That's is not its purpose not even close. Hopefully I missed a comment or something because you could not be that stupid.
There where no comments only two questions.This is for us non marine drillers. Just what is a marine riser and why do you have to change?
Awesome "Red Zone Management" 😆 Nice job, but F...... H...!!!
