Selected Project 1: Mariner Platform Topsides for Statoil (U.K. North Sea)

Key Contributions

  • Package engineer for control & choke valves for the entire platform. Procured over 130 control valves and 25 choke valves in from suppliers including Fisher, Mokveld & CCI as per applicable international standards and Statoil Technical Requirements. This includes valves in exotic materials including duplex, super duplex, titanium and 6Mo.

  • Prepared detailed specifications, datasheets and material requisition documents for control & choke valves. Worked as single point of contact for all necessary technical clarifications during bid phase, verification of control valve sizing calculations, prepared technical bid evaluation documents and final purchase documents for control & choke valves.

  • Participated in the detailed dynamic simulation studies for the complete Mariner process plant. Ensured the dynamic performance of control valves match the overall plant requirement under all conditions including normal operations, process start-up, upset and the variations in well fluids during course of life cycle.

  • Liaise with the control and choke valve suppliers to clear all technical issues after purchase order. Review of vendor documents including datasheets, sizing calculations, GA drawings, test plans etc. Participate in meetings at vendor facilities post PO for kick-off, pre-inspection, FAT etc.
