D3 Consulting have a great wealth of experience in offshore decommissioning, having developed Materials Inventories and Waste Characterisation for more than 45 North Sea Platforms. 

Materials Inventories
D3 Consulting takes responsibility for developing a full materials inventory of everything present on the platform. This is then used by the operator as part of their decommissioning programme for regulatory, contractual and technical requirements. This includes hazardous materials surveys, also known as Inventory of Hazardous Materials (IHM).”

The DAWN Information Management System
At D3 Consulting we provide Waste Assurance to operators and their supply chain throughout the decommissioning cycle. Our unique DAWN information management system has been developed specifically for offshore decommissioning and provides operators with waste assurance and waste tracking through the whole offshore decommissioning cycle. From an initial gap analysis of waste and materials data & information held by operators, Decommissioning Programmes,through to pre-populating bespoke reports and forms, generation of survey and sampling plans, and ensuring that the data held is validated and verified.


Waste Characterisation
Having been involved for two decades with the entire decommissioning cycle, we know the end game for the waste and materials arising from decommissioning works. This enables us to design and carry out pragmatic and robust hazardous materials surveys, materials inventories and residual waste inventories with key factors in mind:

  • Identifying, quantifying and characterising hazardous materials and substances on platforms with ensuing human health risk assessments to feed into the decontamination and dismantling design phase

  • Identifying plant and equipment for resale and reuse with comparisons to scrap values taking into account H&S, costs and processes for dismantling and selling on assets

  • Reaching the optimal recycling rates for topsides, jackets and subsea bearing in mind H&S, cost, programme and compliance

  • Ensuring compliant and documented waste management and disposal solutions for those wastes not recyclable nor reusable

With DAWN, regulatory compliance in waste and materials management just became a lot more straightforward!


Onshore disposal of platforms
With the Duty of Care regulatory requirement, D3 Consulting are often asked by operators to work with the onshore disposal of the platforms, and to provide waste assurance.  As part of our decommissioning service, we carry out yard audits and take responsibility for approbate yard selection. When selecting a yard it’s crucial to understand their level of competence, that they’ve got the right permits and licenses to do the work, that they’ve got enough space, that they’ve got the necessary infrastructure to do the work and also that they’ve got the right experience to do the work.
