DUBAI, UAE – The 700-MW Alpha topsides for the Hollandse Kust Zuid (HKZ) grid connection has departed Drydocks World for the Dutch North Sea.

This is one of two topsides for the complex that will connect the HKZ offshore wind farm zone to the Dutch mainland.

The wind farm zone will have an installed capacity of 1,500 MW and should be fully operational in 2023.

Capt. Rado Antolovic Phd, CEO of Drydocks World, said: “Our focus will now be geared towards completing and handing over the HKZ Beta topside in the first quarter of 2022.”

HKZ covers a 235.8-sq km (91-sq mi) area, 20 km (12.4 mi) offshore the province of Zuid-Holland. It comprises four 350-MW offshore wind farms that will be connected to two 700-MW offshore substations: the HKZ Alpha and HKZ Beta platforms.

Marco Kuijpers, director Large Project Offshore at TenneT, said: “With the load-out and sail away of the Alpha topside to its final destination, we move forward to the next stage of the project; the installation of the topside on the jacket, which is already installed on the seabed.”

The HKZ project is a collaboration between Drydocks World, Petrofac and TenneT. Petrofac contracted Drydocks World to provide fabrication, commissioning and load out for the topsides, including the EPC scope for the HVAC system.

Petrofac is responsible for the EPCI of the Alpha and Beta platforms for grid operator TenneT. Mammoet performed weighing, transport and the load-out of the 3,830-metric ton (4,222-ton) topsides onto a transport vessel.
