Even though offshore energy is still a relatively young field, offshore wind farms are becoming an increasingly attractive investment around the globe. The conditions for building wind parks in the sea are much more favorable than on land – the areas in the sea are large, and no mountains or settlements could complicate the construction.

RNDV provides offshore services such as the production of offshore metal structures and electrical installation. We invite you to deepen your knowledge and get acquainted with five interesting facts about offshore wind farms, their operation, and construction:

  1. Building a wind farm takes 6-12 years

The total time to install an offshore wind farm can vary depending on the scale of the project, location, and available resources. Still, building the park from planning to operation usually takes between 6 and 12 years.

Typically, the construction process of a wind farm is divided into three phases: design, pre-construction phase, and installation. The first stage, which consists of project development, development, and planning, can last 3 to 5 years. Subsequently, about 1-3 years are allocated to the pre-construction phase, during which the necessary contracts and other legal requirements are identified. Finally, the construction phase can take 2-4 years before the wind farm is ready for operation.

  1. 80 wind turbines help reduce CO2 emissions by as much as 80,000 tons

To better understand the efficiency of wind turbines, let’s consider the numbers. Each wind farm varies in size and power, but on average, one wind turbine can generate up to 30 000 kWh annually or more than 11 Millions kWh per year. 

Wind farms help reduce energy dependence on fossil fuels, allow savings, and reduce the total amount of CO2 gas emitted into the environment. 80 wind turbines help reduce CO2 emissions by as much as 80,000 tons.

  1. The transformer platform can weigh up to 3000 tons

Each offshore wind farm has substations (transformer platforms) that collect and transform the produced electricity and prepare it for transmission to the shore. These stations help ensure that as little energy as possible is lost when supplying electricity over long distances.

Substations are installed offshore where extreme weather conditions such as strong winds or waves are common, so they are designed to withstand the harsh marine environment for years. The station itself, without installation at sea, can weight from 200 tons, and the installed and functioning station can weigh up to 3,000 tons.

  1. Wind turbines can last more than 30 years

Building wind turbines is a long-term investment into a cleaner future. Wind parks currently being built are expected to operate for at least 25-30 years. With proper maintenance and operation of the equipment, wind turbines can be successfully used even longer.

As a result, offshore wind farm structures are manufactured and installed with particular responsibility – wind turbines must withstand sea storms and waves and resist sea salinity and corrosion. At the end of the park’s operational period, all structures are dismantled, cut, and delivered to the scrap metal purchase point.

  1. The payback period of the wind turbine is 6 years

When choosing to invest in the construction of wind farms, it is worth considering the turbines’ positive environmental impact and payback figures. The wind turbine becomes climate neutral – i.e., the green energy generated offsets the amount of energy used to produce it – after about 4-7 months of operation.

The payback period for the wind turbine is currently six years. After six years of operation, the installed wind turbine generates profit, reaching 50 to 80 thousand EUR per year. The wind farm, which consists of 80 turbines, generates up to 6.5 million EUR annually.

My journey at RNDV Group started in January 2020. I began as a Project Coordinator and had the opportunity to get a deeper insight into the project components, grasp the feel of the project management processes & the work involved and get to know the people who work not only in the office but also in these projects.

Facing the challenges of the pandemic together

Who said it would always be easy? When I joined the company, the Covid-19 pandemic began. It brought many questions and risks that we had to manage. How will we continue? How will we maintain our staff? Will our projects be suspended? However, this period was not only about the pandemic; it was a test for the whole company. In such cases, you realise the power of teamwork, so we pulled together and got through it.

And although it may seem like I joined the team at the wrong time, I never felt thrown into a project management whirlwind and left alone. Instead, I was surrounded each time by supportive colleagues who advised me on how to perform tasks or solve problems better and more efficiently.

The freedom to work toward a goal

I grew out of my Project Coordinator’s role relatively quickly and was invited by the Production Manager to become an Electromechanical Project Manager. This position brought even more opportunities & flexibility. While the course is set, the way of its implementation largely depends on me. It’s truly fascinating to completely own the project: from the essentials of choosing the people & setting the budget to managing the project to its completion. I’m currently working on projects all over Scandinavia and France.

What could new RNDV colleagues expect?

One of my professional priorities at work is to have opportunities and space to develop. Coming here, that’s exactly what I’ve found. At RNDV, you can gain knowledge and experience from highly competent colleagues and receive in-house training while also travelling, visiting different projects and meeting interesting people.

I wish myself and my new colleagues the confidence to pursue our goals and not be afraid of difficulties because they toughen and strengthen us.

Electromechanical Project Manager Mantas Freitakas

I always wanted to apply my skills and thrive in a well-organized Lithuanian capital company featuring smooth business processes and superb communication. RNDV Group has matched all the requirements, and here I am – a happy Project Manager in the electromechanics field.

Since beginning my journey in the company, I’ve successfully implemented numerous electromechanics projects in different European countries. Whenever I visit the project site, I listen to each colleague, discuss the potential challenges, and find ways to efficiently solve them or simply take time to enjoy the ongoing project. I firmly believe that the overall team’s results depend on the ability to define each specialist’s competencies and perform only those tasks that best match your skill portfolio without taking on other people’s work. I can’t stand routine and am a constant learner, allowing me to grow in both my professional and personal spheres. So today, I’m eager to take full responsibility for my work and strive to solve any arising problems immediately.

We’ve recently finished a project in Spain where we had an incredibly coordinated 85-person team working on high-level processes and tasks with the utmost precision, quality, safety requirements, and strict time frames. Closely observing my colleagues’ work, I always try to help us grow as individuals and as a collective.

I am delighted to work at RNDV Group, as I can plan, create and manage large-scale projects, communicate with a wide array of personalities and do my part in communicational improvements – this is where I find joy. Also, my position covers a lovely composition of freedom and responsibility, and I am a genuine fan of this balance.

If you wish to start your journey with RNDV Group, I encourage you to have the determination to reach for it!

“Upon joining RNDV Group, I got an important role in developing a new shipbuilding subdivision, specifying in the hull assembly. Then, I couldn’t have imagined the growth pace of this branch and that it will so quickly become an independent unit and a new player in the market.”

The hull world was not new for Dmitrij Kiričenko, RNDV Ferrum CEO. Upon joining the RNDV team, he already had 12 years of experience in this field. In his career, he initially started as a welding engineer, and soon after, he became a production supervisor and project manager. As far as he remembers himself, his interest in ships began in his childhood when Dmitrij observed his grandfather working in a ship repair shop.

Even though Dmitrij’s calendar is quite busy nowadays, he found some time to sit down with a cup of coffee and have an open conversation about his exciting journey of bringing a new company to life.

Let’s start from the beginning. How did the shipbuilding branch come to life? 

When I joined the RNDV Group team approximately three years ago, the company was already well-known in the ship construction market as a reliable subcontractor for top-quality electrical installation & piping works. So, it’s only natural for the company to look for expansion opportunities. That’s when the idea to create a shipbuilding branch emerged.

With me joining the company, the big planning stage has begun. First, we needed to do many calculations and market analyses until we felt ready and were assured of our decision to start operating.

How could you describe the team formation process? What was the main success factor in this area?

It took four months from the decision to start this branch to employing the first person. Currently, our team consists of approximately 200 top-class specialists. I believe this is an extraordinary achievement for one year period. However, when planning growth and evaluating success, it’s essential to consider the overall quality of the processes in addition to numbers.

A well-structured team is a central pillar in this activity – even the competitive advantage. Thus, we involved all employees in its formation. Many new colleagues joined us because of recommendations from existing employees.

Another success factor that allowed us to build a professional team is the inner RNDV culture. This company takes an interest not only in the employees’ direct functions but equally, cares for their personalities, free time activities and further career potential within the company.

How did the critical transformation from the branch to an independently operating RNDV Ferrum company occur? Please share how you view the company’s future perspectives.

RNDV Group is a highly ambitious company concurrently developing numerous areas of activity, which are often interconnected. Shipbuilding was a unique, specific, and fast-growing sector; thus, it was decided to separate our branch as it would allow us to implement new ideas and move forward easier. I am happy to be trusted to become the new company’s managing director and a flagman of this sector in the RNDV company group.

Currently, we are developing four main areas: ship hull assembly, ship repair works, piping, and offshore construction assembly. We operate in France, Germany, and Denmark and have further expansion plans into other countries. We prepare for upcoming projects with the utmost precision for the growth to be smooth; thus, the team is expanding each day.

The first independent RNDV Ferrum projects will start this year. Also, we must finish a few projects started by RNDV Group. According to the plan, most people will be employed in the new company until the end of this year.

What would you wish for your RNDV Ferrum team?

I wish my team to stay ambitious in seeking their goals and never stop striving for more!

I am always impressed observing their work and am happy to call us a real power team, able to help each other in difficult moments. We even chose the company name together. Team members offered their ideas, and by voting, we decided to select the RNDV Ferrum title, perfectly matching our niche – works with metal.

RNDV Support Foundation

RNDV companies employs about 350 citizens of Ukraine. Their families need all kinds of help during the war in Ukraine. RNDV is ready to provide assistance to the families of the employees of RNDV who are fleeing the war, including transportation from the Ukrainian-Polish border, temporary accommodation, maintenance, employment-related assistance, assistance to arriving persons in integrating into life in Klaipeda, and the like.

The Public Enterprise RNDV Support Foundation was established in order to bring together those who want to contribute to the support. Not only the customers of RNDV, but also the employees of our companies make their donations to the foundation, and the whole RNDV companies actively contributes to its activities.

“As soon as we heard about the situation in Ukraine, we’ve reacted instantly to provide all the necessary support for our employees and their families. The people of RNDV companies volunteered together and established a RNDV Support Foundation to provide help and support for those in need. Our strength lies in our unity,” – says the CEO of RNDV Support Foundation, Simonas Kalnelis.
