Cable Repair Procedure Risk Assessment

Cable Repair Procedure Risk Assessment

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
