  • Routing
  • Burial Risk Analysis
  • Burial assessment
  • Tool selection and achievability based upon in house experience
  • Cable Protection
  • Ongoing Support to ensure continued Protection of cables including post lay analysis and review of protection measures and cable-soil interaction studies

FOUNDATION DESIGN

Expertise in all design phases of offshore foundations, including:

  • Basis of Design
  • Concept, FEED and detailed geotechnical design of shallow and deep foundations
  • Skirt penetration assessment for shallow bearing foundations
  • Penetration resistance of suction installed piles
  • Pile driving assessment considering up to date recommendations on calculation of resistance
  • Pile driving hammer recommendations and efficiency optimisation
  • Recommendations and design of installation support requirements
  • Back analysis of installation data
