The technology stack of nng offshore wind

Platforms and foundations: fixed vs floating

nng offshore wind centres on two broad platform types. Fixed-bottom installations are anchored to the seabed with jackets, piles or gravity-based structures and are typically used in shallower waters. Floating offshore wind, by contrast, uses buoyant platforms tethered to the seabed, enabling access to deeper waters where wind resources are abundant. The choice between fixed and floating depends on site conditions, seabed geology and logistical considerations. Both approaches are essential to expanding the geographical reach of offshore wind and increasing overall capacity.

Turbine technology and rotor design

Modern turbines deployed in nng offshore wind projects push rotor diameters and hub heights to maximise energy capture while maintaining structural integrity.
