Subsea Separator Development
Exploitation of deep sea oil fields tips the economics of gas-liquid separation in favour of a subsea solution, but prediction of separator efficiency - across wide-ranging operating conditions over the field life - becomes critical for liquid pump selection. Mathematical modelling and CFD simulation were used alongside a scale model test programme to support separator design decisions and to develop a methodology for the design of a full-scale unit in a deep water development in Gulf of Guinea - the first ever to be installed from the start of field life. Project objectives...more
Subsea Stab Connector - Pressure vs. Flow Assessment
Moffat 2000 designs and manufactures subsea pipeline products including stab connectors for flushing or pig-driving operations. Wilde CFD was asked to characterise the pressure-flow relation of various sizes and orientations. In particular, the project was to determine loss coefficient for different size connectors and to establish dependence on orientation of the connector in the line. A model of each unit was generated in ANSYS DesignModeler by cleaning up an imported CAD file supplied by the...more
Water Injection Valve Characterisation
Red Spider Technology supplies the oil and gas industry with a range of down-hole products including seawater injection valves. In an initial study, Wilde CFD established an efficient valve characterisation methodology subsequently used to characterise a range of valve sizes. The analyses were conducted using modules of ANSYS Workbench v11.0. Post-processing identified the fluid force on the poppet and hence fully open flow rate. The actual valve assembly comprises Red Spider’s valve, a...more
