Lessons Learned on 20 years of challenges to internal corrosion protection of subsea pipelines-corrosion inhibitor or pH stabilization?
The three phase fluid of the massive South Pars reservoir under the Persian Gulf, is transmitted 100Km to onshore facilities via numerous 32” API 5L pipelines. The wet sour fluid cont ains 0.5 mol% of H2S and 1.7 mol% of CO2 which forms a hostile environment to carbon steel. Hence, as per form er laboratory researches at design stag e in about 20…
Maximising Accuracy Of MFL Pipeline Inspection
There have been significant advances in magnetic flux leakag e (MFL) in-line inspection (ILI) technologies in recent years. These have led to imp rovements in Probability of Detection (POD), Probability of Ide ntification (POI) and Probability of Sizing (POS).
Whilst often the main focus of these advancements is the inspection vehicle itself, the…

We present a…
Safely repairing subsea flanges on flexible flowlines with a flexible bridging jumper structure
As offshore pipelines age, the oil and gas industry must properly maintain equipment to prevent leaks. In subsea flowlines, leaks sometimes originate from aging flanges. These flanges must be replaced. Historically, replacing the flange has required a lot of time. Different costly approaches are available, from subsea reparations to flowline…
Surge protection for insulating joints – suitable spark gaps and evaluation of the installation
Insulating joints are used for the electrical separation of pipeline systems or for dividing pipelines that are affected by high voltages into sections. The electrical isolation of cathodically protected systems is maintained until the dielectric strength/ flashover strength of the insulating joint is reached. Overvoltages which occur as a result…
