Rig Drawworks Checkist :
• Record the date of the last drawworks overhaul (API RP 7L Section 4.2).
• Check the NDT inspection reports for the brake bands, linkage and equaliser bar.
• Review the wear reports for the brake bands and brake rims (IADC Drilling Manual, Chapter F).
• Check for wear on the brake linkage and look for "kicking" brakes.
• Inspect the wear on the drill line/LeBus groove.
• Ensure that at least twelve wraps of drill line are left on the brake drum, with the travelling block in the lowest position above the rotary table (check OEM for reference).
• Check the condition of the drill line clamp on the dead end of the drill line behind the brake rim flange.
• Make sure that there is enough spare drill line for the duration of the contract or well.
• Verify the kickback roller setting (⅛- to ¼-inch play).
• Carry out a cathead pull test: minimum make-up cathead 7,000 lbs line pull, and break-out cathead 14,000 lbs line pull (3,175 kg and 6,350 kg, respectively).
• Check the condition of the make-up chain (maximum allowable link wear 10%).
• Check condition of the break-out line.
• Check the foundation bolts.
• Ensure that the lubrication oil pressure is within the OEM-required range (20 to 50 psi and 1½ to 3½ bars for most common drawworks).
• Review the monthly oil-sampling analysis reports.
• Check that the oil sprayer nozzles are not blocked.
• Check if silicone sealant is being used as gasket material on the covers.
• Review the inspection records of the chain stretch: maximum allowed stretch 3% as measured over five links (API Spec 7F Section A.3.5).
• Check for wear on the sprockets (API Spec 7F Sections A.3.4 and A.3.5).
• Carry out a function test of the Crown-O-Matic or equivalent system daily and before tripping pipe
• Confirm that any DC motors used inside the hazardous area are fitted with spark arresters and EX space heaters in the event the exhaust air is vented inside the hazardous area.
• Confirm that the electric cables and junction boxes if installed inside the hazardous area have an EX rating (API RP 14F [2008] Section 6.4.7.2). (API RP 500, Fig 75)
• Ensure there is sufficient cooling-water capacity for the brake bands and the Baylor eddy current brake (minimum 150 US gallons per minute = 570 litres per minute when using a Baylor type 7838 unit).
• Ensure there is sufficient cooling water for the auxiliary disk brakes (195 gallons per minute = 740 litres per minute).
Want to say thank you for this incerdible video!!
I’m uploading more
The best video ever I have seen on TH-cam for the drawworks system. Thanks to Transocean whole Drilling team.
here for spacex. cant wait to see what they lift with theirs!
Me too!
you all prolly dont care at all but does anyone know a tool to get back into an instagram account..?
I was dumb forgot the account password. I love any assistance you can offer me
@Brayan Diego instablaster =)
@Mustafa Zion thanks for your reply. I got to the site through google and im waiting for the hacking stuff now.
Takes a while so I will get back to you later when my account password hopefully is recovered.
@Mustafa Zion it did the trick and I actually got access to my account again. I'm so happy:D
Thank you so much, you saved my ass :D
These videos crack me up. I was roughnecking when derricks were wood and roughnecks were iron. Biggest rig I ever worked on we had raise and lower the derrick twice a day. You kids now days think you're roughnecks when in reality you work on post hole diggers.
get over yourself lmao - you probably couldnt hack it out in saudi on my jackup dude, why hate? this is an extremely informative video.
Very nice thank you give more videos
Right Here !!! Get Your Brake Pads Here !!
That's cool thanks.more more...please about rig components
Upload a video for single rigs plz
Buddy ..please load more videos..we always appreaciate your nice videos...thank you
Thanks for the informative video
Wire wrap drawworks manually and auto piece of wood will do. True experience. 5thgear speed wrap. 500. Billion dollars for the art.
Very educative video.
Think you so much you give me an idea on how the work i want to known more agian think you
with the nov 9000 hp draworks, landed a 2.5 million string of casing on the noble sam croft
Great Video, I have learned so much.
nice,thanks.
Could you please share one complete video of Topdrive?
Very nicely explained thank you
You are welcome
good
The Drawworks has to lift all the drillpipe you see on the left that is racked back. ..my guess is 5" Dia (not the tool joint at each end)
That' is probably near a mile of pipe downhole and not all
The rig mast and the rigs components are designed for this load.
Drill Baby Drill !!
Same on trident 12
OMG this new technology is so amazing. 😂
I was with Sonat back in '96 when Transocean bought them out
Transocean is not a very good company to work for!
RIP drill crew of deepwater horizon
8:35 Hope that doesn't happen with Starship!
Good , if with more details is better
👌
Should the drill line storage spool unspool from the top or bottom of the spool?

applys to all drums
Gid
lets just say that, blood & body parts are not good lubrication!!
God but can some vedio translate in arabic
Some Drillers don't like it when I would slide down the dead line, it's the quickest way to get to the floor from the monkey board !!!!😂😂😂😂😂😂😂
