BorWin5 Onshore – De Romein GmbH involved in Bringing about the Energy Turnaround

Major project BorWin5 for safe and low-loss transport of green offshore electricity progresses – De Romein GmbH builds land route from Hilgenriedersiel to Garrel converter station with egeplast Protection-Layer Pipe System Power Protect. To connect the EnBW He Dreiht offshore wind farm with 230 kilometres between the offshore platform BorWin epsilon and the Garrel/Ost converter station, TenneT has initiated the grid connection project BorWin5. De Romein GmbH is taking on the civil engineering and cable laying works on the land line and relies on egeplast Power Protect PE protective pipe systems for the 55 km long section to be piped. The BorWin5 project by TenneT Offshore GmbH includes the establishment and operation of a grid connection between the offshore platform BorWin epsilon and the Garrel/East converter station in the Cloppenburg district. The makeup of the 320-kV-DC BorWin epsilon – Garrel/East (BorWin5) line which features a total length of around 230 km is complex. Roughly speaking, it is comprised of an offshore and an onshore segment. From the BorWin epsilon offshore platform, the line initially runs across the Exclusive Economic Zone (EEZ) offshore and then extends to the border of the 12-nautical mile zone. From there, it runs offshore to the island of Norderney and then across or underneath the island , followed by a segment across the Mudden Sea (mud flats) to the landing point close to Hilgenriedersiel and then further along the onshore land line to the converter station Garrel/East. The highvoltage cable system for BorWin5 consists of three cables (two conductor cables and one control cable) jointly laid in a cable trench.
