In this paper, numerical studies were carried out on scour around a subsea pipeline. A coupled solver between computational fluid dynamics (CFD) and discrete element method (DEM) was selected to simulate flow particle interactions. To select validate the model parameters in solver, angles of repose incipient motion simulated. From validation studies, coefficient rolling friction with spherical ...

There are many challenges associated with development of offshore petroleum fields. Subsea production facilities are increasingly used in the petroleum industry as the technology has matured and quality increased. The use of subsea technology has advantages as well as challenges. Based on a literature review this paper identifies some if the development challenges related to the design and oper...

Maintenance strategies for subsea oil and gas production installations entail the use of specialized equipment and vessels to carry out subsea interventions. The costs for carrying out preventive maintenance are significantly lower compared to the costs of unpredicted failures where in some cases it is necessary to reduce or stop the oil production. Based on a literature review and inputs from ...
