Heavy-lift specialist Sarens is executing the large-scale pre-assembly of 15MW wind turbines for Poland’s first operational offshore wind farm. Operating out of the Port of Rønne in Denmark, the company is tasked with handling nearly 289,000 tonnes of components on behalf of turbine manufacturer Vestas.
The logistics campaign supports the construction of the Baltic Power Offshore Wind Farm, a 1.2 GW renewable energy project spearheaded by project owner PKN Orlen.
Handling massive 15MW components
The Baltic Power project will feature 76 wind turbines, each boasting a capacity of approximately 15MW. The sheer scale of these next-generation turbines requires immense lifting power and precise marshalling at the staging port prior to offshore installation.
Sarens is responsible for the complete handling, lifting, and pre-assembly scope at the port. This includes moving 76 massive nacelles weighing approximately 715 tonnes each, 304 tower sections weighing up to 228 tonnes each, and 228 rotor blades tipping the scales at 117 tonnes per unit.
A dedicated crawler and SPMT fleet
To maintain a continuous flow of components from vessel load-in to temporary storage, and finally to the quayside for pre-assembly, Sarens has mobilised a formidable fleet of heavy-lift equipment to the Danish port.
The lifting operations are being executed by a mix of high-capacity crawler cranes, including a Demag CC 9800 and CC 6800, supported by Liebherr LR 1350, LR 1300, and LR 1280 units. For the horizontal transport of the heavy components across the terminal footprint, Sarens has deployed 80 axle lines of Self-Propelled Modular Transporters (SPMTs).
Once completed, the Baltic Power project, located 23 kilometres north of the Polish coastline, will supply around 4 TWh of clean electricity annually. Sarens noted that its turnkey engineered solutions and heavy-lift capacity are critical to maintaining the logistics schedule for this landmark development in Poland’s energy transition.
