... ABSTRACT The assessment of structural strength of membrane tanks onboard ships to transport liquified natural gas is generally based on sloshing-induced impact loads. These loads are usually determined via model tests for the ship sailing in short-crested wind seas having a cos 2 spreading...

... ABSTRACT Control of ductile fracture propagation to ensure arrest is critical to design of pipelines transporting dense-phase CO 2 . Two factors that control crack arrest are fracture resistance and decompression pressure from the escaping fluid. Current engineering methodologies treat...

... calculation results. INTRODUCTION At present, diesel engine is still one of the main power sources for ships. The working process of diesel engine will produce NO x , SO x , PM, CO 2 , CO, HC and other pollutants, which are the main causes of haze, photochemical smog and acid rain. In the long-term...

... & Storage) projects for reducing the CO 2 emissions are accelerating due to the "Net Zero by 2050" published by the IEA (International Energy Agency). The CCS is a technology that captures industrial CO 2 and stores it on the deep underground, and it is a potential carbon removal method in the industry...

... of the hydrate formation process because the hydrate formation would be initiated under non-equilibrium conditions. INTRODUCTION Gas hydrates are ice-like crystalline solids made from water and guest gas such as methane and carbon dioxide (CO 2 ), and, in general, thermodynamically stable under high-pressure...

... ABSTRACT Limited to the factors like platform space and cost, generally the offshore natural wet gas contained high content of CO 2 is just dehydrated and then compressed to onshore gas plant for further CO 2 removal. So far there is no offshore application for CO 2 removal with solvent...

... Abstract In heterogeneous capillary pressure fields, a number of capillary barriers can exist and CO 2 accumulates below them. This phenomenon is regarded as capillary trapping for CO 2 sequestration. To analyze the amount of CO 2 trapped and leakage, wettability as well as heterogeneity...

... Abstract To overcome unfavorable sweep efficiency of CO 2 flooding in heavy oil reservoir, an integrated gel treatment with CO 2 WAG flooding has been regarded as one of the possible technical suggestions. However, the effects of flowing gel viscosity have not been studied much in previous...

... Abstract The laser welding process for manufacturing pipe was advanced from the conventional single-beam welding method using one high power CO 2 laser to a twin-beam laser welding method using two high power fiber lasers arranged in tandem on the weld seam. Using the newlydeveloped welding...

... Abstract Offshore carbon dioxide (CO 2 ) pipelines could pose an accident hazard risk for offshore infrastructures, ships and the marine environment. The Joint Industry Project Sub-CO 2 will explore CO 2 subsea releases by generating data from well-defined experiments under different...

... Abstract CCS (Carbon dioxide Capture and Storage) is expected as one of the effective solution for global warming. When CCS reaches on demonstration and practical stage, we have to estimate the risk of CO 2 seeping accident for marine ecosystem. In this thesis, we numerically simulated...

... Abstract Based on the replacement of CH 4 with CO 2 + N 2 (also called "swapping"), we demonstrated the direct recovery of methane from artificially synthetic methane hydrate sediments. The injection of CO 2 + N 2 existing as a gaseous state at deep-sea conditions of high pressure and low...

... Abstract Calcium phosphate cement, prepared by acid-base reaction, is reported for the first time in China to prevent CO 2 corrosion of cement. The calcium phosphate cement slurries, composed of calcium phosphate cement, retarder and fluid-loss additive, have been prepared successfully...

... Abstract The state of the art in laser and laser-arc hybrid welding of thick steel components is reviewed, particularly with respect to possible applications in the oil and gas industry. The most relevant information comes from the shipbuilding industry, where the CO 2 laser-GMAW process...
