Hollandse Kust Zuid Alpha topside on its way home

The topside for the Hollandse Kust Zuid Alpha High Voltage Alternating Current (HVAC) offshore transformer station has left the UAE. The 700 MW Alpha topside was built at Drydocks World’s fabrication facility in Dubai. It is the first of two. The second topside is due to leave Dubai next year.

Together they will form part of TenneT’s Hollandse Kust Zuid (HKZ) grid connection, that will connect the offshore wind farm with the mainland at Maasvlakte.

Petrofac is responsible for the complete engineering, procurement, construction and offshore installation of both. The company selected Drydocks World in Dubai for the fabrication of the topsides.

“The safe and successful completion of the first topside fabrication and it’s departure from the UAE is another milestone in this important renewable energy project. Collaboration has been key and together with Drydocks World, our focus remains firmly on the delivery of the second topside for its departure next year. We will then look forward to successful grid connection, to the full satisfaction of our client TenneT.”

Elie Lahoud, Chief Operating Officer – Engineering & Construction at Petrofac

The fabrication of the topside started in 2020. 2.57 million work hours went into building the 3,800-tonne topside.

“Despite the challenges and setbacks as a result of the COVID-19 pandemic during construction, we delivered the Alpha topside timely to finalize the connection of the offshore wind farm to the Dutch grid as planned. Our focus will now be geared towards completing and handing over the HKZ Beta topside in the first quarter of 2022.”

Capt. Rado Antolovic Phd, CEO of Drydocks World

Heavy lift and transport specialist Mammoet was commissioned to perform the weighing, transport and load-out. The topside will be placed on the jacket foundation that was already installed in September 2020. Heerema Marine Contractors’ semi-submersible crane vessel Sleipnir will perform the installation.
