This paper presents a methodology to estimate the probability of failure of every individual corrosion defect and the residual likelihood of failure of an overall corroded pipeline segment after selected repairs, using structural probabilistic analysis. In this paper, a data-driven model is applied to derive optimum maintenance strategy for a petroleum pipeline. The model incorporates structured expert judgment to calculate the frequency of failure, considering various failure mechanisms.
This paper reviews the mechanisms of initiation and the prevention of top-of-the-line corrosion (TLC). Recent research and developments are highlighted and validated to arrive at best practices for control of this significant corrosion manifestation. Water condensation and/or hydrate formation at the top of pipelines are serious design/operation considerations in pipelines. This paper reports the results of tests conducted in a new experimental setup constructed for investigating gas-hydrate risks in varied operational scenarios.
Are Gas Pipelines Really Impossible To Build? The growing opposition in the US for new natural gas pipelines comes as supply and demand continue to grow. Pipelines are necessary for the transport of the gas. Why is there a disconnect between the two? The natural gas pipeline is co-financed by the EU, with work beginning immediately.
The methodology is the industry’s first to address CUI. Along with DNV GL’s new technology, maintenance costs may be reduced by up to 50%. With these synopses of technical papers from OnePetro you can join the author for conferences in Kuala Lumpur, New Orleans, and Lagos, all while sitting in your chairs and without any travel expenses. This paper reviews the mechanisms of initiation and the prevention of top-of-the-line corrosion (TLC). Recent research and developments are highlighted and validated to arrive at best practices for control of this significant corrosion manifestation.
Equinor awarded multimillion-dollar contracts to Aker Solutions and Wood for work on the oil field in the Norwegian Continental Shelf. It said about 70% of the contracts for the development phase is expected to go to Norwegian companies. One of North America’s biggest midstream companies is getting a new chief in the new year. He will oversee the construction of a 1,200-mile-long pipeline that has been a decade in the making. Global market conditions have impacted Magnolia LNG’s ability to reach FID.
Approved in October, the Flow Measurement Technical Section will help engage the greater SPE technical community in flow-measurement-related issues and technologies. It will cover the full spectrum of flow measurement, including single-phase and multiphase flow. At a water treatment plant for an onshore oil field in northern Germany, formaldehyde injection was started in 2015 as a biocide. The goal of this study was to understand the chemical parameters and microbial distribution in the water system and whether formaldehyde injection was effective. To facilitate testing and comparison of products that attenuate microbially influenced corrosion under field conditions, a method using microorganisms from a low-tide, anoxic North Sea sample was developed that allows corrosion measurements to be made for corroding biofilms grown on steel surfaces.
Penspen will also carry out engineering services on the Zirku Island plant. Wood is Shell’s exclusive partner for Shell’s Smart Choke technology, which suppresses riser-induced slugging. A small core team with the ability to make decisions was responsible for getting a subsea tie-back project up to sanction within a short-time frame. SPE’s technical sections offer communities rich with industry expertise. And your engagement adds to the wealth of knowledge to be shared.
