... ABSTRACT Large offshore floating platform needs to be connected by connector, which is a weak link in the structure and has a great influence on the safety of the floating platform structure. Therefore, it is necessary to carry out relevant research on the structural strength of connectors...

...ABSTRACT ABSTRACT This paper introduces a BHA with integrated casing cutting and fishing tools applied in offshore operations of well abandonment. This kind of tool systems successfully applied in an offshore project of permanent abandoned wells. The advantage of the system is the combination...

... ABSTRACT In August 2016, four swimmers carried away offshore and died at Ishikari-hama beach in Hokkaido, while, in recent years, several other similar accidents occurred around the Ishikari coast. In the past, analysis of the Ishikari Bay due to the seasonal wind has been conducted. However...

... public attention to the environmental pollution problem. Among renewable energy resources, both offshore wind and wave energy are resources with great potential. Offshore wind technology has also rapidly developed in recent years, with a trend towards larger scale wind turbines, deeper water depth...

... parts were modelled to investigate the interactions between the DTV, the topsides and the jacket. The results of analyses have been approved by a MWS. INTRODUCTION There are two methods for topside installation at offshore fixed structure. In case of heavy integrated topside, lifting method...

.... In addition, a change in the wave and flow patterns around the artificial reef according to the plane arrangement including the number of openings, offshore distance, and structure length was examined, and their effects on the beach stabilization were considered based on the experiment result. INTRODUCTION...

... ABSTRACT A new Computational Fluid Dynamic tool, based on OpenFOAM, was implemented to reproduce a physical wave tank for offshore applications. The code has new boundary conditions for deep water wave generation, a new turbulent model and a new numerical restraint to represent realistic...
