Mass Impregnated (MI) DC cable with
Integrated Return Conductor =>
eliminates the use of Sea return electrodes.
Fibre Optic element integrated
Next step :
500 kV extruded polymer alloy
=>
lighter in weight and reduced cost
Technological status
Nexans installed the worlds first 170 kV 3-core XLPE insulated submarine cable to the Horns Rev offshore wind farm in 2002. Cable length 21 km Power transmission capacity 160 MW Step 2 (210 MW) of this wind mill farm “Horns Rev II” (43 km) was installed

Dynamic AC cables
Nexans Norway has experience with dynamic MV XLPE AC cables since 1980’ies
Platforms, FPSO
In-house expertise on dynamic analyses and cross section analyses by Riflex, UFLEX
Dynamic applications
Very long cables(> 120 km, 7000 MT)
Marine Installation – Laying
Protection against hazards, such as
Fishing
Anchoring
Dropped objects
Protection
Very small risk of cable or
pipeline damage during
operation
• Trenching in soft to hard sediments
• Trench depth 0.5-3 m
• Operation to 1000 m water depth
No external forces imposed to
cable or pipeline during
trenching
Operational close to
cables/pipelines/platforms
without risk of damage
Trenching of pipeline
crossings
