Total E&P Indonesie’s (TEPI’s) Technical Integrity Management System (TIMS) is the company's means of ensuring that the people, system, processes, and resources that deliver technical integrity are in place, in use, and fit-for-purpose throughout the whole lifecycle of the assets, to avoid major accidents while meeting production objectives. The system covers four key elements: plant, people, process, and performance.
The TIMS is applicable to all operational activities and assets under TEPI custodianship, from early conceptual studies, engineering, construction, and operations up to site restitution. Adherence to the system is applicable for all TEPI personnel, contractors, subcontractors, suppliers, service companies, or any other organizations or personnel performing work in connection with TEPI activities or assets.
The paper will share experiences of implementing the TIMS with feedback from the operational entities as risk owners.
The objectives of the TIMS are managed through following steps:
- Set up integrity policy and procedures: issuance of company procedures
- Set up integrity-management network: appointment of discipline integrity engineers and specific elements lead engineers
- Set up and monitor integrity performance: sitese entities, and affiliate integrity dashboard reporting and monitoring
- Create major-integrity-threat (MIT) work flow: identification of potential integrity threats, threat risk evaluation, mitigation, and remedial-action definition, MIT declaration, MIT actions follow-up, MIT closed out
- Manage safety and environmental critical element (SECE) on the basis of technological risk assessment study results: SECE identification, alignment, implementation, reporting, and follow up
- Management review and endorsement: management review through specific meeting
- Audit and verification: cross-functional entities verification
The main keys to the success of the prevention of major risk in oil and gas operation is the active participation from all of the involved entities with cooperation and coordination.
TIMS has been used for the last 5 years. Improvement opportunities have been identified and implemented continuously through the years.
The TIMS focuses on the major integrity threat zone of the matrix in Fig. 1.
