One of the greatest challenges for the production of petroleum in deepwater is flow assurance. In fact, knowledge about the transient cool down behavior of the produced fluid is necessary to prevent the formation of hydrates and solid deposits during shutdown periods, which could result in a pipeline blockage and could result in large financial losses. In a typical subsea petroleum production s...

Emulsion of waxy crude oil is one of the common states in the subsea pipeline. At low temperatures in offshore environment, waxy crude oils with water could form the crude oil emulsion gel of oil-in-water emulsion. Thus, the waxy crude oil emulsion viscoelastic behavior for deep sea transportation and restarting pipeline safety is particularly important. By means of MASIII HAAKE rheometer which...

Abstract As one of the most important assets in transportation oil and gas products, subsea pipelines are susceptible to various environmental hazards, such as mechanical damage corrosion, that can compromise their structural integrity cause catastrophic financial damage. Autonomous underwater systems (AUS) expected assist offshore operations personnel contribute pipeline inspection, maintenanc...

Most of the subsea pipelines in Indonesia are installed using S-Lay method with pipelay barges equipped mooring spreads, tensioners, and stinger. During pipeline installation, static loads occur due to configuration from firing line barge up seabed. The pipe will experience axial tension bending moment two critical areas: overbend sagbend. In addition, fatigue during installation environmental ...

Mechanical pressure clamps are examples of innovative tools commonly used in the oil and gas industry for arresting leaks from damaged oil and gas pipelines. However, if leaks result from pipeline rupture, clamps are not usually recommended. It is therefore obvious that inspection of the leaking pipeline is very crucial in deciding the strategy for repair. For subsea pipelines where underwater ...
