Low risk would indicate no action required, Medium risk entries would require mitigation and High-risk items would be potential ‘deal breakers’. Further work was indicated to determine the current status of much of the subsea equipment, a diligent and thorough examination of the available data would be required in order to quantify the condition of the subsea infrastructure.
Rectification of the numerous facilities and vessel related issues on an existing FPSO. Peritus Floating Systems developed a scope of work and cost estimate for the rectification of issues on the FPSO, inclusive of work execution and engineering management.
Peritus were contracted to perform re-analysis of the flexible risers and umbilicals, to assess the impact of bilge keel modification to riser responses, and to perform fatigue re-analysis on selected risers. The FPSO operated offshore Brazil in 1065m water and there are over 20 flexible risers and umbilicals installed on the turret-moored FPSO. Peritus’ scope included:
