Recommend to stop by our experts and learn what we think about P&A in #odfjelltechnology

Have seen a hundred footer only once in 2004 it was for an offshore Trestle; a Firewater pump rated 250 HP, 1800 rpm, and 100 ft long which has a right angle gearbox at top of Trestle because its driven by an emergency Diesel Engine. The pump had about ten stages, vertical turbine type. The Seawater at 40,000 ppm salinity was too agresssive for the original Chrome Cast iron construction, so we decided to do reverse engineering and change all pump volutes, impellers, column spiders, to Duplex SS [ or it may have been 316}. The long Columns were already made of 316 SS pipe and flanges, so these were fine. It was the first time in our company to make a large complete reverse engineering and local company casting so i was proud of our efforts. We asked years later about the pump and it seems to have jumped to an MTBF of ten years minimum which was superior to its much shorter lifespan in the past, about 3 to 4 yrs. *************************************************************************************** Was asked a question on Seawater Pumps Bushings, this is answer: For vertical multistage pumps in *** Crude Oil *** service, as long as Columns are well aligned to each other, we found that bushings made from Nitronic-60 will give over 15 years. For Seawater service, many types available; some good, some outstanding, some give short service life: Polymer Thordon bearings give excellent life, Teflon bearings with Graphite are fine, Rubber Cutlass bearings are not bad, Leaded Bronze is suitable but only with very good column alignmnet otherwise life will get short. Most important is to ensure height of pump is enough so that pump does not drag sand particles from Ocean soil. Also, the exact bearing clearance is tricky to get right, too large and will have vibration and early failures, too tight and they will seize. I think best formula for Seawater pump Polymer bushings in vertical turbine types is: Shaft OD x 3.5/1000. Sometimes will need lubrication grooves, depends a lot on L/D ratio of bushings. For Medium hard Lead-Bronze Bushings: Use Shaft OD x 4.0/1000. Last but not least: Always apply a weld cladding [laser is best] on all the lineshaft bushing journals, this will extend life by 300%, no kidding. Material choices of cladding: Stellite, Tungsten Carbide or Martensitic SS. Hardness of cladding at least Rockwell-C 45 and above. Don't use Coatings or HVOF, not reliable here.

Excellent technology and the future of drilling…

  "Our mature supply chain coupled with our US manufacturing and superior field service provides the best wellhead solution at the lowest cost. While other wellhead companies are raising prices to support margins in a shrinking market, Downing offers this industry leading wellhead system at the lowest price.    I just finished giving our quarterly town hall to the Downing Team. We have a lot of exciting milestones to talk about including our Freedom Series HotSwap that recently continuously pumped for over 153 hours. One highlight was that the same engineering team that has developed the award-winning best-in-industry completion surface system, Freedom Series, has also been quietly working on the best wellhead system in the industry. We have undersold this technology as we have focused on our exciting Freedom Series completion technology.      Our MB4 wellhead system with the Surface Casing Mandrel and offline cementing is best-in-class. The internal latch system sets perfectly every time. The offline cementing quick connect is a metal-to-metal seal. The Surface Casing Mandrel latches in minutes without putting a person in the cellar. The running tools are compact and universal. The wear bowl uses a coarse thread instead of a J latch allowing you to pull the wear bowl even in the toughest conditions.     Contact sales@downingusa.com to learn more about our industry-leading wellhead technology."    Brian Wiesner  President, Downing  #haynesville #midcon #permianbasin #permian #eagleford #eaglefordshale #marcellus #utica #bakken #djbasin #DowningUSA #completions #oilandgas #energyforward #safety #automation #continuouspumping
