Fast production
NjordFloat uses a revolutionary manufacturing process enabling production speeds up to twenty times faster than traditional module manufacturing, supporting short lead-times and helping meet demanding floating offshore wind project schedules.
Quick installation
A minimal part count ensures efficient installation during deployment. As an integral buoyancy module with no separate clamps, NjordFloat enables quick installation while reducing offshore installation complexity.
Bend protection
NjordFloat includes innovative bend protection at both ends. Integrated bending stiffeners limit cable curvature, helping reduce the risk of damage from overbending in highly dynamic offshore environments.
