In the offshore industry, the term "engineering" encompasses preliminary engineering through detailed engineering inclusive of pre-service and in-service analyses. The history of the oil and gas industry indicates an influx of mature oilfields which has lead to a greater number of assets in modern day that require maintenance and engineering beyond their design life. Dealing with the aged assets, the industry requires three major spreads in analyses domain, e.g.,

• Asset Life Extension Study [ALES]
• Asset fit-for-purpose or Integrity assessment
• Asset abandonment or decommissioning

While the ALES may mainly need in-service assessment on the structures ‘as-is’ condition, the integrity or fit-for-purpose assessment needs more detailed analyses beyond the stretch or normal elastic domain.

In the context of the oil and gas industry, decommissioning essentially means dismantling, removal and disposal of the structure forming part of those assets and their associated infrastructure, along with plugging and abandoning the underlying wells and restoring the sites. The engineering is required for three basic execution steps involved, e.g.,

• Reverse Engineering – essentially module installation process in reverse
• Lift – removal of complete module by single lift
• Demolition – or asset dismantling in-situ adhering to rigorous environmental & safety regulation

Over the years Bentley SACS has become one of the most trusted, single suite of software to deal with all ranges of critical issues related to asset integrity, life extension and decommissioning. Engineers and managers are making important design and inspection/maintenance and optimization decisions based on the accurate stress analyses results produced by SACS.

Join offshore engineering experts, Kaushik Mukherjee and Nurfaiza Mat, to learn how you can save time with SACS decommissioning tool.

In this webinar, we will:

• Share decommissioning market outlook
• Discuss typical workflow of a decommissioning project
• Showcase the SACS decommissioning tool
