Pulling & Supporting Power & Subsea Cables in the Wind Sector
Slingco have developed a range of cable grips (commonly referred to as cable socks) specifically tailored to the needs of the renewable energy sector – working with Slingco we have produced engineered and customised solutions using cable grip innovation for Boskalis, NKT, Nexans, DEME and other major cable laying contractors for the connection of wind farm projects globally.
Thorne & Derrick have extensive ranges of marine cable grips and hose restraint grips – applications including LV MV HV EHV cable installation (onshore and offshore), support and gripping of cables inside wind turbines, pulling cables shore-to land, substation cable laying and general cable management. We have also developed a range of cable pulling grips for use in the installation and pulling of inter-array and export cables from offshore windfarm installations. We offer a complete range for cable diameters up to 350mm , 10Te to 90Te+ MBL in galvanised steel, stainless steel and aramid fibre.
Marine Grip Options
Option 1 – Limited Lay Down
Galvanised cable grips with aluminium ferrules are suitable for cable installation / loading and typically used for OSS pull in.
Option 2 – Limited Lay Down / Wet Storage
Galvanised grips with galvanised steel ferrules for installation / loading with limited wet storage that can be further extended for longer wet storage with the addition of an anode.
Option 3 – Lay Down / Wet Storage up to 1000 Hours
Stainless steel cable grips with stainless steel ferrules for laying and limited wet storage up to <1000 hours, subject to inspection after such time elapsed.
Option 4 – Lay Down / Wet Storage over 1000 Hours
Non-metallic grips in Aramid for used for cable laying and wet storage applications over >1000 hours, these would be the preference of the leading installation contractors based in the Netherlands and Europe, degradation was not seen other than some signs of salt on the surface. Non-metallic cable grips are specified to provide safe cable handling and are used for offshore saltwater environments when prolonged lay down durations are required.
