Installation of cable support frames on the HelWin Beta offshore converter platform

As part of the connection of the Kaskasi II offshore wind farm to the HelWin Beta offshore converter platform, b.offshore GmbH took over the planning, procurement and installation of the necessary supporting structures for the 155 kV high-voltage cables for TenneT.

A particular challenge was the protection of the immediate assets such as high-voltage and telecommunications cables and the systems that were already in operation. Flexible constructions made of system profiles were installed in the smallest of spaces in order to avoid hot work. b.offshore also planned, delivered and installed the HV cable wall penetrations. In total, more than 5 tons stainless steel installed.

b.offshore was supported in the planning and manufacture of the cable support systems by the Oglaend company, as well as in the offshore installation work by the Krebs group.
