    Use of HAN and EGMBE for pressure test - additional hazards to consider

    Morning everyone, I've got a question about using certain chemicals for high pressure leak testing of umbilical tubes. We have been asked to use both HAN and EGMBE (as well as a 50/50 combination of the 2) for a pressure test. After reviewing the MSDS for the chemicals, they both state that...

    Leaving steel body pig in flowline for hydrotest

    Many thanks LittleInch. We are planning to do an onshore test with a piece of project pipe. I was just trying to gather as much background information as possible on potential issues that might come up, both at the test and in the field. From responses here it seems that there is very little...

    Leaving steel body pig in flowline for hydrotest

    The goal is different for each project. One goal is to insert a pig train into the flowline that will be left for later dewatering operations by our client. Due to shcedule/vessel restraints, we would like to perform as many operations from the platform instead of mobilizing both a platform...

    Leaving steel body pig in flowline for hydrotest

    Good Morning, I was wondering if anybody has any experience leaving a steel body pig/pig train in a flowline during hydrotest/leak test? The pig itself is designed with no enclosed cavities so the pressure should not affect the integrity of the pig itself. But I haven't been able to find any...

    API 6A Test Flange - Which test connection type to use

    Thanks for your response. I must have missed where they discuss the 15k max TP. I'll have to go back and look at Figure 19 again. We finally got a decision to go with the 9/16" connection. The test pressure for this test is based on 30 CFR 250 requirements as the piping will be outboard...

    API 6A Test Flange - Which test connection type to use

    Good morning, I've got a question related to the test flange requirements in API6A. We have piping segments that will be installed offshore and will have 10K API 6BX flanges on either end. In order to test the segments prior to going offshore we are looking to have test ports tapped but I am...

    Water Soluble Bags Used for Biocide Treatment of Subsea Flowline

    Good Morning, I am trying to find information on the use of water soluble bags of biocide being inserted into a flowline during manufacture that will protect the flowline following installation and flooding operations. I have treated flowlines before but only by injecting it from the topsides...

    SmartPlug Experiences

    Does anybody have experience using a SmartPlug (or similar competitor version)? Background info: 1) Pipeline is 20in subsea gas export line 2) Operating Pressure = 3000psi 3) Cleaning and gauging runs will be completed before using SmartPlug to make sure pipeline is clean, hydrocarbon free...

    What is a typical career path for a MWD field engineer.

    I started out as an LWD/MWD field engineer straight out of school as well. It wasn’t with Haliburton so my experience is probably very different from yours, but I’ll throw my two cents in anyway. I found that making a 3-year or 5-year plan was very difficult. There were around 250 (probably...

    Rupture Disk Sizing

    John, Thanks for the link. I know my question was pretty vague, but to be honest I didn't really know what specifically you would need to ask in order to size a burst disk. I was brought into a team that was working on a pressure relief system and was just looking for some basic information...

    Rupture Disk Sizing

    Morning everyone, Does anybody have a quick calculation for sizing rupture disks? I’ve looked at API RP 250 and spoke with our flow assurance group but I’m not looking to produce a full flow assurance model. I’m just looking for something that will get me in the ball park for sizing for a fluid...

    Helicopter Underwater Egress Training

    I’m still relatively new to the offshore oil and gas field (approx. 4 yrs experience), but both companies I have worked for required HUET and SafeGulf as a bare minimum before going offshore. The clients that I have worked for have all had client specific safety courses that they required...

    Short Infield Umbilical Installation in Deep Water

    Good Morning, Does anybody have experience installing an infield umbilical that is shorter than the water depth? We are reviewing the layout on my current project and have come up with an idea that would require about 1/3 of the original umbilical length, but brings up the problem of installing...

    Subsea Controls Communication Question

    Sorry for the delayed response. Hurricane Ike has put me behind on just about everything and I'm just starting to catch up. Thank you both for the advice. Chief, I haven't heard of the microwave signal either, but I will be sure to do some research online to see what I can find out. Cheers, Kat

    Subsea Controls Communication Question

    Good morning everyone, Sorry for the re-post, but it was suggested that I might have better luck posting in this forum rather than the Control Systems forum. I have been assigned to a companywide project that will eventually become an in-house training program. I'm still new to the industry...
