The jacket foundation for TenneT’s Hollandse Kust (Noord) Offshore Substation is now entering the final stages of fabrication. with the roll up completed and the 2-part cable deck now successfully installed.
Currently the jacket for the 759 MW Hollandse Kust Noord offshore wind farm is under construction at the Vlissingen fabrication yard of Heerema. In 2020, TenneT selected the joint venture ENGIE Fabricom – Iemants contract for the engineering, procurement, construction, offshore installation, connection and testing of the offshore transformer stationLast year, UK based engineering company SLPE was responsible for the detailed design of the offshore transformer station jacket and foundations.
As part of the project, SLPE has designed frames to house ‘biohut’ cages, which will be filled with oyster shells. These cages replicate the ecological function of a shallow water nursery to help support a sustainable biodiversity of the marine offshore environment.
“It is always a proud and exciting moment seeing our hard work coming to fruition on the fabrication yards of Smulders and Heerema”, said Sam Lawes, Head of OSS Substructures at SLPE. “Our team has worked efficiently and decisively throughout the entire project, keeping to tight schedules and doing all we can to surpass our client’s expectations.
“It is also both encouraging and rewarding being part of a project that has taken a proactive approach towards sustainability. Our oceans are a vital resource that we must all work hard to protect. This project is a great example of one of the many ways the offshore industry can play a significant role in preserving and restoring the health of our oceans”.
The sail out will follow later this year. The topside is scheduled to leave the yard in Hoboken in the spring of 2022.
Hollandse Kust Noord
The 759 MW Hollandse Kust Noord is a project by CrossWind, a consortium of Shell and Eneco. The wind farm is located some 18.5 kilometres off the Dutch coast at Egmond aan Zee. The wind farm will feature 69, SG 11.0-200 DD 11 MW Siemens Gamesa wind turbines. It is the third wind area where TenneT’s 700 MW standardised AC connection will be applied. Photo source: SLPE
