The vision of a green planet and excellent engineering

Project name: Onshore / Offshore plant 400, 220, 34 kV for wind power plant connection (Walney Extension Offshore Wind Farm)

Investor: DONG Energy (presently Orsted)

Contractor: Pro Integris for DONG Energy

Subcontractor: HELB Ltd for Pro Integris

The year of completion: 2016.

Hoboken Yard (Antwerpen, Belgium) – Platform building
Irish Sea – Delivery

Walney Extension, the giant project of Danish Ørsted, is the largest wind power plant in the world with a total capacity of 660 MW. The wind power plant includes 90 Siemens and Vestas turbines with installed power of 7 MW and 8 MW and the height which ranges from 190 to 222 meters. They cover the Ireland Sea area of 145 km2. It is the equivalent of 20,000 football fields, and enough energy is produced to supply nearly 600,000 households annually with the creation of 250 new job positions. HELB’s hardworking team of engineers played an important role in this great project, testing the offshore substation of wind power plant.

An important part of an exceptional project

By testing the different parts of the plant, the integration of all systems into one functional system was performed. The activities included, among other, testing of switchgear, protection panels, metering and current transformers on 220 kV and interfaces between control and protection cabinets. HELB is proud enabling electricity supply for next generations, and this project is the proof that we pay great attention to ecology, especially in the light of the fact that Walney is huge investment in renewable energy sources.

Revolution of Renewable Energy Sources

Platforms holding substations of the wind power plant were primarily produced in Antwerp, Belgium (Hoboken Yard). After the testing they were shipped by the raft to the Irish sea. This giant project of record capacity has been completed within the planned deadline and budget in June 2018. HELB’s engagement on the wind power plant, which is the true revolution of renewable energy sources, lasted seven months.

Damir Poljak, B.Sc. Managing Director, Pro Integris d.o.o.

“In the period from 2016 to 2019, we co-operated with HELB on four major projects for offshore wind farms: from works at the shipyard (Belgium, Denmark), to works on onshore substations and offshore platforms (UK, North and Irish Seas). Colleagues from HELB made great team with engineers from other companies involved in projects. They demonstrated expertise, diligence, and great dedication to fulfilling the goals as well as resourcefulness when needed. We would especially emphasize the flexibility and adaptability of both field engineers and business leaders. In HELB, we have found a reliable and quality partner for cooperation not only on construction jobs on wind farms but also with other power energy projects.”

Latest case studies

With a Chinese partner in the construction of the largest wind farm in Croatia

In December 2021, with the push of a button, the 156MW Senj Wind Power Plant was put into trial commission. It is the largest wind park in Croatia and includes the construction of 39 wind turbines with a single power of 4 MW on an area of 65 square kilometers, of which 29 wind turbines are located in the area of the town of Senj, and 10 in the area of the municipality of Brinje. This is the first major Chinese investment in Croatia worth around 230 million euros. And it all started with the excellent cooperation of Norinco, Youtone, and HELB. More

Over 100 facilities in 6 months

HELB has successfully completed the project of energy audit of a large company for Croatian Air Traffic Control at over 100 facilities that Croatian Air Traffic Control uses for its activities throughout Croatia. HELB was the main contractor for the project, which lasted six months, and four other companies participated, with a total of six engineers from various professions. More


In a recently completed project, HELB once again proved to be one of the leading companies in the field of energy efficiency – this time in the energy audit of a large company. For the branch of the renowned Swedish Pervanovo group, Bjelin Otok Ltd, HELB experts carefully analyzed the energy situation and gave recommendations for energy savings. More
