2008 - KBR, Saga Kristin TLP Project, Norway
Summary
The Saga Kristin Tension Leg Platform (TLP) project was a deepwater offshore development in Norway’s North Sea. The floating platform was designed to extract and process hydrocarbons from deepwater reservoirs while maintaining stability under extreme environmental conditions.
Challanges
Floating platforms experience continuous dynamic forces, requiring specialized reliability modeling for station-keeping, mooring systems, and production equipment. High-pressure and high-temperature (HPHT) wells introduced integrity challenges for subsea infrastructure and topside processing equipment. Due to the offshore location, planned maintenance windows were limited, necessitating high reliability of safety-critical systems.
Solution
Conducted RAM analysis to model equipment downtime scenarios, ensuring that critical production and safety systems had the necessary redundancy and fail-safes.
Developed availability models for the platform’s mooring, risers, and processing equipment, optimizing maintenance planning.
Led HAZOP, SIL, and LOPA workshops, verifying safety system integrity and ensuring compliance with IEC 61508 and IEC 61511 standards.
Implemented real-time monitoring strategies for mooring integrity and subsea equipment to reduce unplanned interventions.
