Life extension of ageing offshore structures

As the industry seeks to increase the economic life of its offshore assets, many will remain in operation longer than anticipated. Some oil and gas assets have been in service for more than four decades.

Extending the lifetime of an asset means it can continue fulfilling its intended function without compromising its design, technical or operational integrity while extracting further value.

The process of extending the lifetime of an ageing asset will vary according to the type of asset, company specific requirements and regulatory regimes.

DNV has developed a five-step approach for all assets in the oil and gas value chain:

• Current condition assessment
• Life extension evaluation and GAP analysis
• Technical qualification for life extension
• Obsolescence preparedness
• Life extension costs and plans.

It is crucial to proactively manage the safety, reliability and performance of an oil and gas asset once it is operational. DNV’s transparent and independent approach to asset integrity management, asset optimization, and technical and marine assurance enables customers to monitor, predict and ensure the safe performance of all their assets.

This on-demand webinar provides guidance on the safety review and management of ageing offshore installations. It will also look at how fatigue analysis, structural strength reviews and risk assessments can contribute to the preparation of measures to extend the life of critical offshore equipment.
