Offshore Wind Majors Launch Floating Substations Joint Industry Project

DNV, together with 30 industry partners, has launched a new Joint Industry Project (JIP) aimed at improving technology development for floating offshore wind substations, with a particular focus on how export cables and topside equipment tolerate movements of a floating substructure.


The objective is to align industry best-practice allowing for accelerated technology development and to close gaps in available substation standards enabling scaling of floating offshore wind with an acceptable level of commercial, technical, health, safety, and environmental risks, DNV said.

According to DNV, the company developed the standard DNV-ST-0145 document, together with partners from the industry, which provides the technical requirements for the certification of electrical offshore substations.

For its latest update, more than 500 industry comments were reflected in this standard which is of increased importance as a growing number of projects pursue new concepts. The results of this JIP will be used to update the standard making it applicable for floating offshore substations.

The companies that have joined the project as partners are ABB, Aibel, Aker Solutions, Atlantic Offshore Energy, BP, Burns & McDonell, EDF, Elia Group, Shell/Eolfi, Equinor, Falck Renewables, GE Renewable Energy, Gicon, Hitachi Energy, IV One & Nevesbu, Mitsubishi Electric, Northland Power, Oil States Industries, Ørsted, Prysmian, RWE, Saipem, Siemens Energy, SSE Renewables, Technip Energies, TechnipFMC, Terna Plus Srl, TotalEnergies, Wood PLC, and Worley.

DNV started looking for partners to launch a new JIP for floating offshore substations back in November 2021.
