Erosion, corrosion, and erosion-corrosion are common problems in offshore pipelines, tubing and pipe fittings. Corrosion has an important impact on the total cost of oil and gas production. Considering the diversity of corrosion related problems, CO2 corrosion (sweet corrosion) is probably the material degradation mechanism most extensively assessed in this industry over the last 30 years. In t...

To achieve the Net-Zero Emissions goal by 2050, a major upscale in green hydrogen needs to be achieved; this will also facilitate use of renewable electricity as source decarbonised fuel hard-to-abate sectors such industry and transport. Nearly 80% world's offshore wind resource is waters deeper than 60 m, where bottom-fixed turbines are not feasible. This creates significant opportunity couple...

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...

Abstract The application of FRP composite is quite well demonstrated in strengthening on RC structures but steel still being investigated by many researchers. aggressive marine environment can cause corrosion to the offshore pipelines which would affect structural performance such as pitting could be considered most destructive was simulated this research. This study had attempted carry out exp...

This article is devoted to the construction of offshore pipelines, taking into account protection environment. Initially, information was provided on conditions pipelines. Then there a discussion about methods laying their pros and cons, therefore choice method, which economically viable takes We know that main factor in choosing any method submarine pipeline economic environmental factors. Und...

Recent years, offshore outsourcing has received large amount of attention from both industry and academia because of its attractive advantages such as cost reduction, talent access. As an alternative way to implement information systems in operation management, offshore insourcing has been greatly overlooked. Though organizations shun from the contractual obligations in offshore insourcing, the...

• We develop a methodology to combine geographic information systems and energy system models via data clustering. This novel is applied the north sea region. The offshore grid eases integration of up 338 GW wind. A power-based reduces costs by 8.7 bn € (4.1%). power-and-hydrogen 14.9 (7%). North Sea Offshore Grid concept has been envisioned as promising alternative to: 1) ease wind onshore sys...

Abstract In offshore engineering, the phenomenon of free span often occurs, and pipeline may have multiple spans adjacent to each other, forming a multi-span pipeline. The interaction different makes structural vibration characteristics more complex, which change fatigue affect safety structure. this paper, model tests were designed explore vortex-induced (VIV) pipelines investigate mechanism. ...
