The offshore transformer station of the Hollandse Kust (zuid) Alpha platform is efficiently put in on the jacket within the North Sea, about 20 kilometers off the coast of The Hague, on Sunday December twenty sixth 2021. The transformer station, additionally known as topside, is likely one of the two topsides of the Hollandse Kust (zuid) offshore grid, which is able to join the offshore wind farm space with the identical identify to the Dutch onshore high-voltage grid.
Marco Kuijpers, Director of Giant Tasks Offshore: “With the set up of the Alpha topside, the offshore grid that TenneT is constructing within the North Sea is beginning to take form. Hollandse Kust (zuid) Alpha is the primary connection of an offshore wind farm to the Maasvlakte, with a capability of 700 MW. Wind power performs an important position within the power transition, additionally in trade, and I’m proud that TenneT can contribute to a sustainable future on this method.”
From Dubai to the North Sea
Over the previous yr, contractor Petrofac has been engaged on the fabrication of two Excessive Voltage Alternating Present (HVAC) transformer stations Alpha and Beta on the Drydocks World fabrication yard in Dubai. Mid-November, Mammoet, a specialist in heavy transport and lifting, took care of the weighing and loading of the three,830-tonne Alpha topside onto the transport vessel Tai An Kou. From Dubai, the Tai An Kou sailed in a single month to the Alexiahaven on the Maasvlakte, the place it arrived on Tuesday December twenty first.
Offshore firm Allseas carried out the set up
Within the Alexiahaven, the Alpha topside was loaded from the transport vessel onto the multipurpose platform set up and elimination vessel Pioneering Spirit of offshore firm Allseas, which then sailed to the set up location within the North Sea. After completion of preparatory work, Pioneering Spirit precisely positioned the Alpha topside on the substructure, also referred to as jacket.
“It’s nice to be concerned in an power venture of such strategic significance to the Netherlands,” mentioned Edward Heerema, President and CEO of Allseas. “Pioneering Spirit has made a reputation for itself lately with pioneering lifts within the oil and gasoline trade. The profitable set up of the Alpha topside demonstrates the flexibility of the vessel and our added worth within the power transition.”
Important milestone within the supply of this vital power transition venture
Sami Iskander, Petrofac Group Chief Govt, provides: “The secure set up of the Alpha topside is a big milestone within the supply of this vital power transition venture. Everybody concerned ought to be happy with this achievement. Petrofac has been constructing a profitable observe document in offshore wind for greater than a decade now, which displays the aptitude of our engineers and the standard of our supply. We’re collaborating carefully with our companions on the upcoming supply of the Beta topside and profitable grid connection.”
The Beta topside – additionally with a capability of 700 MW – is predicted to observe within the first quarter of subsequent yr. When the wind farm space Hollandse Kust (zuid), developed by wind farm developer Vattenfall, is absolutely operational in 2023, it’s going to generate an quantity of renewably power that’s equal to the annual consumption of greater than two million households. Hollandse Kust (zuid) is the primary subsidy-free wind farm space on this planet.
