Depending on the prevailing bathymetrical and geotechnical conditions, the integrity of offshore pipelines is threatened by potential slope instabilities that occur at the seabed or at the bottom of lakes. In addition, submarine slides are more frequent in seismic regions. The instability of onshore slopes under seismic conditions is undoubtedly a…
PETRONAS
PETRONAS is considering pipeline repurpose option for one of its CCS projects in Malaysia. One of the opportunities identified is to repurpose existing gas export pipelines, 24in and 30in with combined distance of 200km from offshore to onshore. Existing technical frameworks from available standard and internal resources for pipeline repurpose…

Encroachments on buried HP Gas pipelines represent 50% of accidents on pipelines world-wide. The consequences for pipeline owners can be critical, resulting in fatalities and injuries, but also economic cost: shutdown of refineries, damage to the environment, etc… This is a huge issue for both types of pipelines. For older existing pipelines…

External factors such as global supply chain challenges, the push for Net Zero and an ongoing introduction of new pipeline regulations have raised concerns about the integrity of aging pipelines. Aging pipelines carry their own risks which can lead to product leakage, ruptures and explosions if left unaddressed.
This article takes a look at the…

Product theft has been a major issue for many pipeline operators around the world. We all have in mind the terrible explosion of a gasoline pipeline in the town of Tlahuelilpan, in the Mexican state of Hidalgo. The blast killed at least 137 people and injured dozens more. This story made its mark, but illegal tappings is not an isolated fact.…

Ensuring the safe operation of flanges is critical to the integrity of piping systems in the oil and gas industry. Given the intense conditions that process equipment often experiences, flanges are subject to a variety of defect mechanisms, such as corrosion, scratching, gouging, pitting, or denting. These defects can lead to flange leakages that…

Corrosion Under Insulation (CUI) of insulated pipelines and leakage or intrusion detection on underground utility pipelines are two applications where Distributed Fiber Optic Sensing (DFOS) provides a promising alternative to existing monitoring techniques. In this paper, we present case studies for both domains.
When Distributed Acoustic Sensing…

It is generally accepted that the effect of cathodic protection is based on the activation polarization and the concentration polarization of the steel surface resulting in an increase of the pH at the interface between steel and soil. This increase in pH value may affect the adhesion of the corrosion prevention coating in the immediate vicinity…

Methane Emissions Reduction System in Pipeline Compressor Stations: ENAGAS & BAKER HUGHES Experience
Baker Hughes / Enagás
Methane is the second most abundant anthropogenic greenhouse gas (GHG) after carbon dioxide: it is estimated1 that its concentration in the atmosphere is approximately 2.6x higher than the pre-industrial levels and this contributes for at least 25% of the global warming.
As methane is the main component of natural gas, a strong reduction of its…
