Follow the Live Construction of the Baltyk 2 & 3 Offshore Wind Farms
The Baltyk 2 and 3 offshore wind farms will be among the most significant renewable energy projects in Poland and Central Europe. Once operational in 2028, they will power around 2 million Polish homes with clean electricity, playing a central role in Poland’s shift away from fossil fuels and its goal of 5.9 GW of offshore wind by 2030.
With LAUTEC’s public Baltyk 2 and 3 demo, you can now follow the project’s progress in real time.
Track Installation Progress and Vessel Movements Right as They Happen
Monitor the construction progress of the Baltyk 2 and 3 offshore wind projects through our interactive SaaS Platform demo. With daily milestone visualizations and vessel locations refreshed every 2 minutes, following the wind farms’ buildout has never been easier.
Our SaaS Platform tracks major construction milestones, including:
- Rock installation – Laying crushed rock scour protection around each foundation position to stabilize the seabed and prevent erosion caused by tidal currents and wave action.
- Monopile installation – Driving the hollow steel pile foundations into the seabed at each turbine location. The monopiles for Baltyk II+III measure between 50 and 70 metres in length and are installed using a specialist gripper frame to ensure precision positioning.
- TP & secondary steel installation – Mounting the transition piece on top of each monopile, followed by the addition of boat landings, ladders, and work platforms. The boat landings allow Crew Transfer Vessels (CTVs) to push against the structure when transferring technicians safely offshore.
- WTG installation – Transporting and installing the Siemens Gamesa SG 14-236 DD wind turbine generators, each rated at 14 MW, onto the prepared foundations. With a rotor diameter of 236 metres, each turbine can power an average Polish household for a full year in just 10 minutes at full load.
- Offshore substation installation – Installing the jacket foundation, topside module, and rock scour protection for the offshore transformer platform, which steps up the voltage for efficient long-distance export.
- Inter-array cable pull-in – Pulling the 66 kV inter-array cables up through the base of each monopile and into the wind turbine generator. This connects each turbine individually to the subsea cable network, forming the first critical link in the chain that carries electricity from rotor to grid.
- Offshore export cable lay & burial – Four export cables with a total length of 256 kilometres transmit electricity at 220 kV from the offshore substations to the onshore substations. The cables are laid on the seabed and buried, with the landfall section completed using a trenchless method to avoid disruption to the coastal zone, connecting finally to the Słupsk-Wierzbięcino substation on the Polish national grid
- Inter-array cable lay & burial – Following pull-in at each turbine, the 66 kV inter-array cables are laid across the seabed between turbines along each string and subsequently buried into the seabed with a total cable length of 200 kilometres

Through the demo, you can see exactly when these milestones happen, tracking:
- Van Oord’s vessels as they carry out subsea rock installation, with four specialised vessels deployed to prepare the seabed for foundation installation.
- Heerema Marine Contractors’ heavy-lift vessel Thialf as it installs all 100 monopile foundations and transition pieces, as well as the two offshore substation jackets.
- Seaway7’s vessel as it installs approximately 200 kilometres of 66 kV inter-array cables connecting all 100 turbines to the two offshore substations.
- Cadeler’s O-Class and P-Class vessels as they transport and install all 100 Siemens Gamesa SG 14-236 DD wind turbine generators, with operations commencing in 2027.
- The Jan de Nul and Hellenic Cables consortium vessel as it lays and buries the four 220 kV offshore export cables spanning 256 kilometres to the onshore substation at Słupsk-Wierzbięcino.
- All other vessels operating at the Bałtyk 2 & 3 site.

About the Baltyk 2 & 3 Offshore Wind Projects
Located between 22 and 37 km off the northern Polish coast near Ustka and Łeba in the Baltic Sea, the 1.44 GW Bałtyk 2 and 3 offshore wind farms are being developed jointly by Equinor and Polenergia, each holding a 50% share. Together spanning approximately 240 square kilometres, the two farms will feature 100 Siemens Gamesa SG 14-236 DD turbines, each rated at 14 MW with a rotor diameter of 236 metres.
This project is being built with the support of some of the most advanced offshore wind technology and top industry experts:
- Siemens Gamesa Renewable Energy is manufacturing and supplying 100 SG 14-236 DD direct drive turbines, each with a blade length of 115 metres and a swept area of 43,500 m².
- Sif and Smulders are fabricating all 100 monopiles and transition pieces, with monopiles measuring between 50 and 70 metres in length.
- Heerema Marine Contractors is deploying its heavy-lift vessel Thialf (over 200 metres in length) to transport and install all 100 foundations, transition pieces, and the two offshore substation jackets.
- Cadeler is deploying an O-Class and a P-Class wind turbine installation vessel to transport and install all 100 turbines, with operations commencing in 2027.
- Seaway7 is responsible for the engineering, procurement, construction, and installation of approximately 200 km of 66 kV inter-array cables connecting all turbines to the two offshore substations.
- The consortium of Jan de Nul and Hellenic Cables is supplying and installing four 220 kV offshore export cables with a combined length of 256 km, connecting the offshore substations to the onshore grid at the Słupsk-Wierzbięcino substation.
- Iemants, a subsidiary of Smulders, is responsible for the design and construction of the two offshore substations.
- Van Oord is carrying out subsea rock installation, deploying four specialised vessels to lay scour protection across the site.
