The Hornsea Offshore Wind Farm Project consists of four offshore wind farms being built off the East Coast in the North Sea. There have been some remarkable achievements on this project, being built further from the coastline than ever before, when Hornsea 1 opened in 2020 it was the largest offshore wind farm in the world, powering well over one million UK homes. However when Hornsea 2 opened in August 2022 it became the largest offshore windfarm, overtaking its smaller brother, Hornsea 1 by powering over 1.4 million UK homes whilst being built at the ‘lowest ever contract price for an offshore wind farm in the UK’ (Orstead, 2023). Orsted, the owner is planning 2 further wind farms in the area around the current Hornsea sites, both are looking to be even larger than the previous two phases!
For Hornsea 1 and 2, SPEL manufactured a large number of products that are very often used on substation products including 5no. SPEL Tankstor cesspool tanks for holding the sewage waste on the site, 2no. SPEL Puraceptor National Grid specification oil separators (National Grid approved separator as developed alongside National Grid over multiple years) and 4 large SPEL Drainguard, bund water control units.
3 of the SPEL Drainguard bund water control tanks were supplied with an extra SPEL Tankstor storage tank that was interlinked to the Drainguard tank to provide extra bund water/oil storage, ensuring that in the event of a large reactor failure all of the oil was successfully contained within the system. The storage of these Drainguard systems with extra storage was between 320,000 litres and 360,000 litres.
SPEL also supplied similar systems for Hornsea 3, with a large SPEL 600 Series (4m internal diameter) Drainguard tank with 220,000 litres of storage. Once again this unit was supplied with oil/water sensitive pumps.
The advantage of having a full Drainguard tank based system is that in the event of a transformer rupturing, all the oil is quickly drained into the tank which is completely enclosed and underground. This greatly reduces the fire risk in comparison to storing all of this oil in an above ground, open topped concrete bund.
