Largest certified offshore wind farm in Scandinavia

In the Dan­ish Baltic Sea, Vat­ten­fal­l’s Kriegers Flak wind farm was com­mis­sioned at the begin­ning of Sep­tem­ber. TÜV SÜD has accom­pa­nied the project on behalf of Vat­ten­fall since 2018 and suc­cess­ful­ly com­plet­ed the project cer­ti­fi­ca­tion. The cer­ti­fi­ca­tion was car­ried out in accor­dance with the Dan­ish BEK 73. 

The Kriegers Flak off­shore wind farm is locat­ed in the Baltic Sea, between 15 and 40 kilo­me­ters off the Dan­ish coast. It con­sists of 72 Siemens Game­sa 8‑megawatt-class wind tur­bines and has a total capac­i­ty of 605 megawatts, which is equiv­a­lent to the annu­al ener­gy needs of around 600,000 households.

“Good coop­er­a­tion has played a major role in enabling us to com­plete this ambi­tious project on sched­ule, despite a glob­al pan­dem­ic, and com­mis­sion Kriegers Flak in Sep­tem­ber 2021.”

The assign­ment includ­ed design cer­ti­fi­ca­tion of the foun­da­tion struc­ture, as well as super­vi­sion and cer­ti­fi­ca­tion of the com­plete fab­ri­ca­tion phase, and the trans­porta­tion, instal­la­tion, and com­mis­sion­ing phas­es in accor­dance with BEK 73 (Exec­u­tive Order from the Dan­ish Min­istry for Cli­mate, Ener­gy and Build­ings, No. 73). As part of the cer­ti­fi­ca­tion, the off­shore wind experts reviewed the design of the wind tur­bines’ monopile foun­da­tions and the con­nec­tion to the tow­er through a so-called tran­si­tion piece. The design review of the foun­da­tions start­ed already in sum­mer 2018 and the project cer­tifi­cate was hand­ed over to Vat­ten­fall in ear­ly Sep­tem­ber 2021. 

 “TÜV SÜD sup­ports the devel­op­ment of inno­v­a­tive and sus­tain­able tech­nolo­gies. We are pleased to have con­tributed to the imple­men­ta­tion of this excit­ing clean ener­gy gen­er­a­tion project,” says Liana Tatar, respon­si­ble project man­ag­er. “The cer­ti­fi­ca­tion con­firms that Kriegers Flak wind farm com­plies with Dan­ish reg­u­la­tions and that the safe­ty of the tur­bines is guaranteed.”
