Skills required

• Specific plant process technology
• Process engineering design and calculation
• Risk assessments including but not limited to HAZOP, HAZID

Phases of projects

Reviewed multiple projects related to offshore gas platforms and onshore gas-and-condensate terminals including: Infill drilling, new gas terminal, process simplification, condensate tie-in to existing plant, condensate recovery plant: Each project covers phases of FEED and detailed engineering; each review includes process flow diagrams (PFD) & piping and instrumentation diagrams (P&ID) reviews, simulation models and basis, HAZOP, safety instrumented systems (SIS) among others.

To protect confidentiality, specific information such as names (facility, or person, or project) are converted to generic names.

Condensate tie-in from a gas central processing platform to terminal

• A large gas central processing platform was under development by a PSC. The gas and condensate would be sent to their own onshore gas treatment plant, also under development. Treated condensate would be sent to our terminal storage tanks. We have to ensure the condensate we would receive and store in existing tanks comply to existing specifications and would not pose hazards to existing assets. The condensate must be within required Reid vapour pressure (RVP) to ensure tank roofs will not be damaged. Contaminants such as mercury or sulfur or dissolved acid gases must be below specification to not damage metal pipes and tank walls. Condensate that will be blended with other PSC condensates must be measured by a metering, and the blended condensate must meet customers’ specifications, such as density (specific gravity), Saybolt colour, and low level of contaminants.
• During P&ID review process, the tie-in point must be decided such that online modification (modification while the plant is running) can be performed, and adequate safeguards are in place such as shutdown valves. Diversions are also required in the event of tank trips or offspec feed.
• A large gas central processing platform was under development by a PSC partner, where our company is a minority shareholder. The gas and condensate would be sent to their own onshore gas treatment plant, also under development. Treated condensate would be sent to our terminal storage tanks. We jointly-performed the concept select of the tie-in as well as multiple technical reviews including P&ID review, HAZOP, HAZID and IPF classification.
