Njord EB & Njord SB, provide long term, stable buoyancy to arrays of underwater equipment. With a full line of buoyancy solutions ranging from 100 meters to 6,000 meter water depths, these buoys are available in numerous sizes and shapes to ensure successful deployment and recovery during mooring expeditions.
With two geometries available, spherical or ellipsoidal, the buoys are low maintenance and extremely rugged to meet the harsh demands of both deepwater and coastal environments. Elliptical buoys are preferred for high current environments when low drag is necessary. Trelleborg's spherical and ellipsoidal buoys are fully able to integrate as a key component in mooring systems.
Trelleborg’s established subsea buoys are manufactured from our proven HDPE (high density poly-ethylene) rotomolded shells, and filled with our in house microsphere and macrosphere fill system. Each subsea buoy is fully customizable for complete design freedom, to accommodate any size, uplift, structural components, or housing equipment needed within the float.
