NGI monitors some of the world's most demanding offshore structures. NGI is well-known for work with innovative foundations such as suction bucket jackets, and has expertise for mooring and floating applications, too.

Borkum Riffgrund 1   

The world's first offshore wind turbine foundation using suction bucket jacket technology, installed as a full-scale prototype in 2014. NGI was responsible for geotechnical design, instrumentation and the monitoring system.

  • More than 100 instruments and 7 km of cable
  • Monitored over several years to validate the concept for later projects

NGI to provide assistance to the installation of suction bucket jackets at Changhua field offshore Taiwan

Ørsted is responsible for the Greater Changhua Offshore Wind Project on the west coast of Taiwan. Framo won the contract to supply suction bucket pumping systems to install the foundation jackets. Framo has contracted NGI to provide geotechnical engineering expertise, instrumentation equipment, and installation monitoring during the fieldwork.

Seagreen - foundation installation for the world's deepest offshore wind farm

Huge buckets, silently sucked into the seabed with the opening down, keep the wind turbines on the Seagreen field off the east coast of Scotland in place on the seabed. Together with FRAMO, NGI had the task of installing the bucket foundations on the 114 jacket substructures for the wind turbines.
