Products of several going and promising onshore offshore hydrocarbon extraction sites both in Russia foreign countries are known due to elevated level corrosive СО 2 . The article analyzes present procedures aimed at rating hazard extracted fluids, selection implementation measures for protection equipment pipelines against inner corrosion. Onshore facilities work within specific environment, w...

Abstract Steel pipes are widely used in offshore structures and buried seafloor pipelines. Buried single-wall pipelines or piles of fixed platforms crossing the earthquake fault can experience very large displacement, which could cause considerable damages failures to pipes. The elevated strains induced from welding connection between also drastically reduce pipe’s performance. Therefore, preve...

The shallow P velocity provides relevant information for offshore engineers, in planning pipelines, piers, and platforms. Standard multichannel surveys trailing long cables provide good estimates but may require stopping other ongoing operations or affect the environment. Monochannel by Boomer systems involve a very short cable, so those drawbacks are minimized; however, this comes at cost of l...

Geological conditions along long distance pipelines are complex. In consideration of differences in elevation and terrain obstacles, long distance pipelines are commonly laid through tunnels. Oil and gas pipelines are often laid side by side to reduce construction costs and minimize geological impact. The layout and construction of parallel oil and gas pipelines are more complex than those of s...

Offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. Thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. A safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. While the cost...
