Nevesbu, together with Iv, has developed a patented concept for a floating offshore substation (FOSS). The concept was already successfully tested in MARIN’s basin. This lays an important foundation for the development of floating wind energy.
Potential of floating wind energy
The energy transition is a hot topic within the offshore industry and the need to invest in large-scale offshore renewables is greater than ever. According to the DNV report ‘Floating offshore wind: The next five years’, 1800 gigawatts (GW) of offshore wind energy is expected to be generated by 2050, of which 250 GW will come from floating wind farms. To efficiently transport this huge amount of energy from sea to land, offshore substations are essential.
To date, however, there are no proven designs for floating offshore substations on the market. The dynamic conditions faced by a FOSS are uncharted territory for equipment and cable manufacturers. The concept developed by Iv and Nevesbu addresses these challenges and is based on proven Tension Leg Platform (TLP) technology. The concept is designed to convert 1.4 to 2.0 GW of power, with a DC export link of 300 to 525 kV.
Testing at MARIN
Nevesbu tested the floating concept on scale model with different configurations of the cable guiding system (CGS). The model test was conducted within MARIN’s SME slot. The maximum wave height tested in the model basin corresponds to the once-in-100-years event west of Shetland, corresponding to Hs > 17.0 metres. An initial high-level verification showed that the measured maximum displacement, accelerations and CGS loads in irregular waves are similar to the results of Nevesbu’s numerical model.
