In the Chengdao oilfield in Bohai Bay, China, a number of offshore platforms had reached the end of their design life, and needed to be reassessed
for extended life considering the security of the platform structures and the maintenance processes required to ensure safe operation. The project
concluded that 90 percent of the platforms could be extended for about 10 years through simple maintenance reinforcement, saving billions of
dollars and returning an annual oil and gas production of 3 million tons.
Using SACS, the team reduced project costs, accelerated project deliverables, and increased the quality of the analytical data required for safe
operation of the marine platform lifecycle and integrity management. The increased collaboration and information mobility provided by SACS
streamlined the communications between site detection and maintenance evaluation activities by the project team.
The primary goal of this USD 3 million project was to evaluate and reinstate the structural integrity of an Abu Dhabi, United Arab Emirates,
platform for resuming oil production after a ship collision and to technically substantiate the insurance claim resulting from the accident. By
identifying possible threats to the platform integrity, the team also prevented damage to the facility and the marine environment by mitigating
any remaining risks.
Using SACS, the Zakum Development Company reduced project time and costs by carrying out preliminary ship impact analysis in house and
outsourced the detailed engineering. Identifying critical subsea nodes optimized inspection times constrained by weather factors. The team’s work
resulted in an early release of the platform for operation and allowed the company to justify the insurance claims.
