Beyond turbines — Integrated Wind Solutions driving offshore to net zero

When people think of offshore wind farms, they often picture the towering turbines and spinning blades dominating the seascape. But beyond these iconic structures lies interconnected services and expertise keeping the wind industry humming. Norway-based Integrated Wind Solutions (IWS) is at the heart of this ecosystem, with an offering ranging from advanced vessels to operations management. We spoke with CFO Marius Magelie about how IWS is positioning itself to accelerate the global shift to net-zero.

“Being a key supplier to the offshore wind value chain is truly exciting,” says Magelie. “This industry has the potential to deliver large-scale green power, which is essential for the shift to renewable energy and meeting global climate targets.”

Established in 2020 and listed on the Oslo Stock Exchange, IWS focuses on providing services aimed towards the construction, commissioning and operations phases of offshore wind farms.

Services powering offshore wind

Offshore wind energy relies on the integration of advanced technologies and specialised services. IWS aims to support the entire lifecycle of offshore wind farms, offering a range of interconnected services across various stages of the value chain.

Leveraging a network of subsidiaries and strategic partnerships, IWS delivers a comprehensive range of services that tackle both the opportunities and challenges facing offshore wind developers: IWS Fleet provides Walk-to-Work Commissioning Service Operation vessels (CSOVs), which offer accommodation for technicians and engineers working on the wind farms, along with a safe and reliable gangway to transfer people from the vessel to the offshore wind turbine. ProCon provides high-quality electrical and technical solutions, while Green Ducklings offers market intelligence and supply chain consultancy. IWS also holds a 49% stake in PEAK Wind, which provides advisory, intelligence, and asset management to ensure wind farms operate at peak efficiency.

Pioneering innovative vessel design to reach net zero

IWS’ “Skywalker Class” vessels represent a leap forward in sustainable marine design. These hybrid-powered vessels are among the first capable of extended zero-emission operations.

“Our Skywalker Class vessels prioritise safety and efficiency in technician transfer for construction, commissioning, and maintenance work,” Magelie notes. With a double-ended hull for enhanced manoeuvrability and the industry’s largest battery pack allowing up to six hours of zero-emission operations, these vessels glide through offshore wind farms, reducing emissions by up to 75% compared to more conventional CSOVs.

The vessels are also outfitted with solar panels and energy-saving heating, ventilation, and air conditioning systems, making them as sustainable as they are comfortable. From a gym and sauna to a game room and client offices, these ships offer a haven for technicians, ensuring they have a welcoming space to recharge between shifts. In addition, the vessels are specifically designed to minimise underwater noise, demonstrating IWS’ commitment to protecting marine life and the environment they operate in.

The standard schedule for operations and port visits consists of 14 days offshore, followed by approximately 12 hours in port, during which the primary activities include bunkering and the exchange of crew and client personnel.

In September 2024, IWS secured a EUR 50 million loan from NIB to finance the expansion of its fleet. “We’re grateful for NIB’s support,” says Magelie, adding that the loan strengthens IWS’s financial position, enabling them to focus on optimising fleet operations  and expand capabilities in the growing offshore wind market.

“The backing from NIB is invaluable as it allows us to confidently expand our capabilities in the offshore wind industry and contribute to the green transition.”

Overcoming challenges in the offshore wind industry

Europe has long been a leader in offshore wind, with over 6,000 turbines installed across its waters. But recent challenges—supply chain disruptions, rising interest rates, and cost increases—have slowed progress. As a result, some projects have been delayed, casting doubt on the anticipated benefits of offshore wind.

“While political ambitions are high, significant bottlenecks remain across the supply chain,” Magelie observes. He points to the UK’s recent Allocation Round 6 results, where 5.34 GW of capacity was awarded across fixed-bottom and floating offshore wind. “Although projects were auctioned, fewer than anticipated were allocated, highlighting the urgent need for sustained budget allocations to meet climate targets,” he adds.

Despite these obstacles, IWS remains optimistic. “The European offshore wind market is expected to grow at a compound annual growth rate (CAGR) of 20-30% by 2030,” Magelie notes. IWS, through its subsidiaries, is poised to support and benefit from this growth, offering the essential services needed to realise these projections. As the wind industry evolves, IWS believes that a focus on innovation and collaboration will help overcome current challenges and drive the sector toward a sustainable, net-zero future.

“Contributing to offshore wind’s growth and building a sustainable energy future is both exciting and rewarding,” Magelie reflects. “The potential for attractive investment returns makes it even more compelling.”
