The Scope
We were asked to assist in the technical evaluation, comparison and risk assessment of three vendor submissions for inter-array cable repair procedures.
The Solution
We reviewed and provided technical comments on procedures from each vendor. Procedures included:
- Interarray cable recovery
- Cable repair methods
- Cable pull-in methodology
- Burial equipment
- Burial methodology
- Cable protection system removal and replacement
- Concrete mattress removal and replacement
- Equipment and vessel selection and availability
- Vendor assessment of geophysical and geotechnical conditions
Our team also completed a risk assessment of the three sets of procedures to identify the technical competence of each vendor with regard to the following categories of risk:
- Technical solution for each procedure
- Cable damage
- Equipment availability
- Spares requirements
- Environmental (including marine conditions and seabed conditions)
- Retrieval/reburial methodology
