Chevron has a portfolio of leases with condition in the High Pressure and/or High Temperature (HPHT) range where Pressure exceeds 15,000 psi and/or Temperature exceeds 350oF. To enable production for such fields, HPHT equipment for Drilling, Completions, Interventions, Subsea Production and Facilities was developed. Further, to enable production the work needed approval from regulatory agencies such as BSEE.
In this presentation a case study of technology qualification of Topsides equipment, i.e. the Boarding Shutdown Valve with 20,000 psi rating will be discussed. Aspects of technical qualification process (TQP), stage gated Technology Selection, and independent third party (I3P) review and documentation of the verification and validation during qualification, will be discussed.
When developing the topsides technology plan there was an opportunity to separate the TQP process and procurement process. A phased approach was defined, which could then be presented to suppliers as a design competition. Each supplier would be expected to successfully complete all qualification phases to be able to proceed to the selection phase. The phased approach allowed for six suppliers to start the process with only two remaining to proceeding to the Qualified Selection stage.
From the perspective of documentation; BSEE defines high pressure high temperature (HPHT) as pressures >15,000 psi and/ or temperatures > 350°F. For the I3P review, focus will be given to the process of review and documentation of risk assessment, technical specifications, verification, validation, and testing and quality plans to the Regulator - BSEE. BSEE requires all HPHT barriers to be reviewed, following the detailed process outlined in BSEE May 2019 Notices to Lessees and Operators (NTLs). To enable this, and to assure the volume of work is deployable on future projects, a design one-build-many (D1BX) framework and discipline was needed.
In summary, a case study will be presented that highlights the Technology Qualification Process, Technology Gated Selection Process and the Regulatory Documentation Process. Effective management of these swim lanes will be presented.
