The engineered plan after the spider deck inspection

The project 

For the decommissioning, the spider deck level has to be accessible. Vulcan spider deck was not maintained, and the condition of the secondary supporting structure was unknown. Hence, an inspection was necessary. The objective of the assessment is to minimize the reinstatement works by decreasing the number of new components. 

Vulcan UR is located approximately 120km east of the Lincolnshire coast, part of the ConocoPhillips Southern North Sea (SNS) Gas Operations.

Spider deck inspection 

To ensure the spider deck is safely accessible for people and tools, Conbit performed an inspection. During which, they assessed the spider deck’s integrity. 

Before the inspection the team traveled offshore, Conbit engineers prepared the plan in which they identified the inspection criteria. They visually checked all walkway supports, walkway stringers, grating, handrail posts, handrail wires, and handrail tubes.

The team also performed a solidity test. All findings of the inspection were documented on the checklist, as well as actions to be taken to provide safe access again.

Performance

The client was very satisfied with Conbit's approach on spider deck inspection of the Vulcan UR platform. Conbit's willingness to meet the deadline despite short notice was appreciated. The engineers' detailed inspection plan was key to the project's overall success. Their high level of operational expertise was observed during the offshore work.
