Subsea Cable Consultancy and Independent Advice
Senior engineering advice for offshore cable projects, drawn from direct delivery experience.
PASSER provides independent subsea cable consultancy for developers, operators, contractors and cable manufacturers. Our consultants are senior engineers and project managers with hands-on experience across HVAC, HVDC, array, export, umbilical and flexible pipe scopes in offshore wind and oil and gas.
Most engagements are a single, well-defined scope. A feasibility review before tender, a second opinion on equipment selection, an independent hazid facilitation, or rapid technical input during a live offshore campaign.
