Offshore Platform, Assessment, In-Place, Pushover, SACSAbstract
The concept of 'life extension' is that there is a time or an amount of duty when the installation would normally be consider for retirement but where with certain processes and criteria. Life can be extended for a further period without a reduction in margins below safe operating limit. Number of existing fixed offshore platforms increased and exceeding the original design life that need to be maintained in production. Reassessment is possible by taking into account the new information and measurements due to the actual behavior of the platform. This paper present structural performance assessment approach for the offshore fixed platform. Assessment of existing structures for life extension based on static linear analysis for component checks, Non-linear analysis for determining ultimate strength.
