For Hywind, Trelleborg Offshore designed and supplied 45 off polymer-coated syntactic foam Distributed Buoyancy Modules (DBMs) which supply buoyancy support for a 3 ton, 100 meter section of cable as it exits the turbine spar and descends to the sea bed at -220 meters.
The buoyancy modules include an internal clamp for secure fastening and precise positioning on the cable. The cable is supported mid-water in what is known as a ‘Lazy Wave’ configuration, featuring gentle long radius curves that minimise stress on the cable while accommodating natural movement created by wind and waves.
