Structural Integrity Managementhurricane.jpg

CougarSIMTM is a managed system for the evaluation of structural integrity to ensure fitness for purpose of offshore structures and enables significant inspection cost reduction. Our SIM system can be efficiently integrated with our GIS system for visualization of data. CougarSIMTM follows the guidance provided in API RP 2SIM and meets regulatory requirements. An entire fleet is risk ranked to determine likelihood and consequence of failure. This is utilized to prioritize remedial measures as part of the mitigation strategy. Likelihood of failure has been bench-marked against assessment results. An ongoing long-term risk based plan is developed utilizing pertinent data and appropriate competences covered by Cougar Offshore's areas of expertise. Inspection strategy and evaluation philosophy is tailored to client requirements. The SIM process provides an annual program of targeted inspection and anomaly tracking. Detailed inspection scopes of work and reporting is standardized with central data management​.

Cougar Offshore SIM benefits are summarized as follows
  • Consequence of failure tailored to client specific business risk model​
  • Specific competencies on all aspects of SIM
  • SIM offers significant cost savings:
    1. Targeted inspection & reduced frequency
    2. Unnecessary repairs avoided through assessment of inspection findings
    3. Efficient repair schemes (often like-for-like not necessary)
    4. Anomaly tracking to ensure timely repairs if required
  • Risk reduction:
  1. Inspection scope determined through structural knowledge, previous inspection findings and assessment results​​ (including bench-marking of likelihood of failure)
  2. Anomaly tracking
  3. Mitigation​

SIM Process.jpgCharacteristic data and condition SIM Process Detail.jpg data​ are used in evaluation and strategy. Evaluation of data includes trend analysis & risk assessment.

Risk Matrix.jpgRisk matrix identifies high risk structures and is tailored to client's business risk model. Changes to risk matrix are viewed interactively as amendments to business risk model are made.

Decommissioning philosophy is integrated with strategy and mitigation to reduce risk exposure.​​

Mitigation may include strengthening to increase robustness, decommissioning, well P&A and/or load reduction to reduce likelihood of failure and associated risk. Examples of load reduction are conductor removal, boat landing and/or barge bumper removal, redundant appurtenance/structure removal and even deck raising​.  Each mitigation can be readily explored to determine effects on likelihood of failure.

 Consequences of failure to fit business model may include:
  • Business disruption
  • Environmental impact
  • Public perception
  • Other operational impact

Inspection plan intervals to suit regulatory and client's requirements. Plan is monitored and amended to suit scope of work executed and from evaluation of inspection findings as part of the rolling plan.

Detailed inspection scopes of work are generated and are targeted based on structure type/arrangement, historic data and assessment results. Unnecessary redundant inspection scopes of work are avoided.

​Inspection philosophy prioritizes inspection based on risk and covers efficient use of resources​ and significantly reduces inspection budgets.
