Hywind Tampen
Hywind Tampen is a floating offshore wind farm 140 km off the Norwegian coast in the North Sea owned by the Norwegian state-owned energy company, Equinor. The turbines are mounted on cylindrical concrete spar-buoy foundations.
The wind farm provides electricity for Equinor's Snorre (platform A and B) and Gullfaks (platforms A, B and C) oil and gas field; Snorre lies just North of the wind farm, and Gullfaks lies just South. Hywind Tampen is the world's first renewable energy power source for offshore oil and gas, and when commissioned was the world's largest floating offshore wind farm. At full capacity, Hywind Tampen will provide 35% of the electricity demand for Snorre and Gullfaks.
Equinor started developing and testing offshore wind installations in 2009, with their first 2.3 MW Hywind Demo project outside of Karmøy, south-west Norway. Equinor also owns the world's first commercial floating wind park, Hywind Scotland, off the coast of Peterhead, Scotland, commissioned in 2017. After full implementation and operation of the wind farm, Equinor will stand for 47% of global floating wind capacity.[citation needed]
The scheduled power production start was in the 3rd quarter of 2022, but complete installation and operation was not in effect until May 2023. The first power production from Hywind Tampen started in November 2022, and was delivered to Gullfaks A Platform. The windfarm was then connected to the Snorre platforms in May 2023, and officially opened in August 2023. Supply chain issues around steel for the tower sections delayed the final four turbines, meaning they missed the weather window and had to be delayed until spring.
Hywind Tampen has an expected economic lifetime of 19 years, bounded by the respective lifetime of Snorre and Gullfaks operations (Snorre until 2040, Gullfaks A until 2034 and B until 2030, and C until 2032). Hywind Tampen is therefore expected to be abandoned in 2041.
The offshore wind farm consists of 11 Siemens Games SG 8.0-167 DD turbines with a system capacity of 8 MW. Each wind turbine has three 81.5 m blades with 176 m diameter rotors. The turbines are installed on individual floating cylindrical spar buoy concrete structures that are linked together in a shared anchoring system. The anchors are fixed on the ocean floor at a depth of 260–300 meters.
At such water depths, it is not possible to install bottom-fixed solutions, which are the more cost-efficient solution. However, 80% of global offshore wind resources are found in deeper waters (past 60m), and the wind is generally stronger and more consistent. Installation of floating turbines therefore requires a large technical expertise and investments, but the wind farm has greater potential for electricity generation. Equinor intends to expand their offshore wind capacity while reducing cost, and their main strategy for doing so is to invest in technological improvements and large-scale building projects.
The concrete foundations are 107 metres (351 ft) tall, with the lower 66 m (217 ft) being 18 m (59 ft) diameter, and the top section reducing in diameter to 8 m (26 ft). They were constructed using a slip forming method by Aker Solutions, who merged with Kværner in 2020. The bottom 20 metres (66 ft) was constructed in a dry dock in Stord, before being towed to the Vindafjord where the remainder was built and the mechanical outfitting completed.
