About this event

On occasions some slightly less "routine" structural assessments are necessary to support operational activities or developments on offshore oil and gas platforms. This talk will describe three such examples: helideck re-assessment, dealing with a combination of steel and aluminium structures, and onshore and offshore design codes; blast assessments of a living quarters wall panel and topsides module; and assessments for a replacement platform crane.

Many colleagues will be familiar with the activities that are performed in relation to structural integrity management (SIM) of offshore assets. These include the development and application of documented SIM systems, incorporating written schemes of examination (WSE), strategies and procedures that cover safety critical element (SCE) identification, risk based inspection planning and support during inspections; anomaly management, assessment and mitigation; weight control and structural model management.

A complementary part of the work involves structural assessments – core linear analyses, including in-place strength, dynamic spectral fatigue and ELE seismic, to code specifications.

Advanced non-linear assessments may be necessary, including static ultimate strength, redundancy, pushover, ship impact and fire, dynamic response under blast and ALE seismic actions.
