Baltic Power has completed installation of all 76 transition pieces at its offshore wind farm located 23km off the Polish coast.
The project said the milestone marks the conclusion of main works for the foundation package, with fabrication supported by local factories in Żary, Niemodlin and Łęknica using steel mostly sourced from Polish mills.
Baltic Power added that installation of wind turbines and export and inter-array cables is ongoing, with around 20 vessels operating daily at the site.
The wind farm is a joint venture between ORLEN Group and Northland Power and has a planned capacity of about 1.2GW.
Each transition piece measures approximately 20 metres in height and weighs up to 350 tonnes, connecting monopile foundations with turbines and offshore substations.
“Reaching the milestone of installing all transition pieces means that we are concluding the main works for the foundation package, achieved through the significant effort of multiple members from foundations, installation and construction teams, among many others,” said Piotr Ostrowski, project director and board member of Baltic Power.
“It is worth mentioning that the fabrication of transition pieces was executed with a valuable input of local factories in Żary, Niemodlin and Łęknica, which provided secondary steel for these massive structures, using steel mostly sourced from Polish mills.”
“For this phase of the installation campaign, our contractor Van Oord deployed a heavy lift vessel capable of transporting up to four transition pieces per voyage, significantly improving installation efficiency offshore,” stated Nick Ingham, deputy EPCI director at the Baltic Power project.
“The vessel is equipped with twin cranes with a combined lift capacity of 2,000 tonnes, enabling the safe and precise handling of large transition pieces during offshore installation.”
