There are no known commercial or technology confidentiality issues around knowing what wastes and materials are in a platform’s topsides, jackets or subsea. There should be no reasons why the Materials Inventory cannot be shared with the supply chain and waste management industry as part of an early engagement initiative to seek best options for the management of the wastes arising.
At D3 we have come across decommissioning projects where the latest version of information (including materials inventories) has not been fully shared in the tender process which later results in Contractor’s unknowns leading to variations and cost increases.

Lesson Learned: Share the Materials Inventory with your supply chain – benefits can arise from early sharing as it will help contractors prepare better for the work, put in place correct procedures to deal with the wastes and increase opportunities to reuse and repurpose plant and machinery
