HDD - Haringvliet crossing

Engineering firm Joulz is currently constructed a new high-voltage connection between Middelharnis and Geervliet, commissioned by Stedin. The 18-kilometre-long connection is part of improvement works to the electricity grid on Goeree-Overflakkee. The connection runs under the Haringvliet, which is around 5 kilometres wide. Visser & Smit Hanab installed two series of casing tubes with a length of 2.5 kilometres, which were connected at the halfway point. The sections were joined together on opposite sides of the Haringvliet at Middelharnis and Zuidland. 126 sections of 20 metres - an impressive length.
