Pfisterer provided and installed a highly flexible 155 kV Feltoflex AC cable forming a bridge between the DolWin alpha and DolWin gamma platforms (overall connection length just over 200 m, with about 4.5 km of Feltoflex HV cable routed between and on the platforms) as part of the DolWin3 converter station connection.
Pfisterer received a turnkey contract, valued at about EUR 6 million, associated with the DolWin3 grid connection to equip the DolWin gamma converter station and its link to DolWin alpha with high- and medium-voltage cable systems. The company designed and installed AC-side internal cable systems on the platforms and supplied and installed a highly flexible 155 kV Feltoflex high-voltage cable forming a bridge connection between the DolWin alpha and DolWin gamma platforms, around 80 km offshore. This inter-platform link, involving approximately 4.5 km of Feltoflex HV cable and an overall span of roughly 200–250 m between the platforms, was implemented as a pilot project to increase availability by enabling switching between converter stations during the construction phase of DolWin3.
