The offshore wind industry is facing one of the most complex periods in its relatively short history. Rising costs, supply chain pressure, inflation and higher interest rates have combined to challenge project economics and slow the pace of new developments. Consumers are asking difficult questions as many face constantly rising energy prices against a promise of greener equals cheaper. Yet the strategic importance of offshore wind has never been greater. Europe’s energy transition, industrial competitiveness, and long-term energy security depend heavily on the continued expansion of large-scale renewable power. Against this backdrop, companies capable of delivering certainty, scale and technical excellence are increasingly vital to the sector’s future.
Among those companies, Cadeler has emerged as one of the most influential players in offshore wind construction and lifecycle services. Headquartered in Denmark, the company has steadily built a reputation as a specialist provider of transportation and installation services for offshore wind turbines and foundations, as well as operations and maintenance support. What began as a vessel-focused business has evolved into a globally recognised partner for developers seeking reliable, technically sophisticated installation capabilities.
Today, Cadeler operates one of the industry’s most advanced fleets of wind turbine installation vessels and is deeply embedded in projects across Europe, Asia and beyond. The company’s strategy has been clear: expand capacity, build technical leadership, and support the offshore wind sector through every phase of the project lifecycle. In a market facing structural headwinds, Cadeler is demonstrating how strategic investment and operational excellence can drive growth even in uncertain conditions.
FLEET GROWTH
A central pillar of Cadeler’s rise has been its continued investment in vessel capacity and technical capability. Offshore wind turbines have grown dramatically in size over the past decade, with next-generation units now exceeding 15 MW. Installing these turbines requires highly specialised vessels capable of handling heavier components, greater lifting heights and more complex offshore conditions.
Cadeler has positioned itself at the forefront of this technological evolution. The recent delivery of Wind Mover, the company’s 10th wind turbine installation vessel, represents another milestone in that strategy. Designed to install and maintain the largest turbines currently entering the market, the vessel strengthens Cadeler’s ability to support increasingly complex offshore wind developments.
CEO Mikkel Gleerup explains the significance of the expansion: “The delivery of Wind Mover, ahead of schedule, represents another step in our long-term strategy to operate the most advanced and versatile fleet in the offshore wind sector. With both Wind Mover and Wind Maker now delivered, we are well-equipped to meet the scale and complexity of global offshore wind projects. After her delivery, Wind Mover will head straight to work installing and maintaining the largest turbines in the market.”
Fleet growth is not simply about capacity. It reflects the broader transformation of the offshore wind sector itself. As projects move into deeper waters, further from shore and with larger turbines, the industry increasingly depends on installation partners with the engineering capability and fleet scale to deliver safely and efficiently. Cadeler’s investment strategy is designed to ensure it remains one of the few companies globally capable of meeting those demands.
PROJECT MOMENTUM
While the industry faces rising cost pressures, Cadeler continues to secure significant project contracts that reinforce its role in the global offshore wind supply chain. Recent agreements highlight the company’s growing reputation as a full-scope transportation and installation partner capable of managing complex foundation and turbine installation programmes.
One such agreement involves a preferred supplier arrangement for foundation transportation and installation scheduled for 2028. The deal reflects the long-term planning cycles that define offshore wind construction, where developers increasingly look to secure experienced installation partners early in project development.
“The signing of this preferred supplier agreement reflects continued confidence in Cadeler’s capabilities within offshore wind foundation transportation and installation,” says Gleerup. “As we continue to build our pipeline of complex foundation scopes and broaden our experience in T&I across jurisdictions, our focus remains on safe execution and reliable project delivery.”
Alongside this agreement, Cadeler has secured two additional contracts covering full-scope foundation and turbine transportation and installation. These deals further demonstrate the company’s ability to deliver integrated services across multiple stages of offshore wind construction.
Gleerup emphasises how the company’s fleet expansion supports this broader market role: “This project reinforces Cadeler’s position as a full-service T&I partner in the foundations space and demonstrates that our strategic direction is aligned with current market demands. With our fleet of nine wind installation vessels – and three additional under construction – Cadeler continues to deliver the flexibility, efficiency, and innovative solutions required to execute increasingly complex projects and to support the necessary build-out of offshore wind globally.”
These project wins arrive at a time when developers are becoming increasingly selective about supply chain partners. Large-scale offshore wind developments require precision engineering, tight installation schedules and a high degree of operational reliability. Companies that can consistently deliver on these expectations are becoming indispensable to the sector’s continued growth.
ASIA EXPANSION
Beyond Europe, the Asia-Pacific region is emerging as one of the most dynamic offshore wind markets in the world. Taiwan in particular has established itself as a major hub for offshore wind development, attracting international investment and building a strong project pipeline.
Recognising the importance of the region, Cadeler has recently expanded its physical presence by opening a new office in Taipei. The move reflects the company’s long-term commitment to supporting projects across Asia while strengthening relationships with regional developers and partners.
“Cadeler’s new Taipei office becomes the hub for expanding our regional footprint – supporting local teams, anchoring client relationships, and coordinating cross-border opportunities as we build momentum for the clean energy future across Asia-Pacific,” says Gleerup.
The expansion also aligns with the growing importance of operations and maintenance services across the offshore wind sector. As early projects mature, developers are increasingly focused on ensuring reliable long-term turbine performance, creating a growing market for specialised service providers.
Through its Nexra subsidiary, Cadeler has secured a significant operations and maintenance campaign in Taiwan, reinforcing its lifecycle service capabilities. Gleerup explains the strategic value of the project: “This contract underlines Nexra’s strength in execution and flexibility to respond quickly to client needs in the operational phase of offshore wind farms. In securing near-term campaigns such as this, Nexra demonstrates its ability to drive utilisation across Cadeler’s fleet, while continuing to deliver the reliability and technical expertise our clients expect.”
The agreement highlights how offshore wind service providers are evolving beyond installation work alone. Lifecycle services – including maintenance, repairs and major component replacement – are becoming a critical part of long-term project economics.
“Being entrusted with O&M work in the Asia-Pacific region reflects the confidence placed in our local teams and our assets,” Gleerup adds. “Nexra allows us to support our clients throughout the lifecycle of their projects – from installation to long-term operations and maintenance, including main component exchange.”
INDUSTRY LEADERSHIP
The broader offshore wind sector may be navigating a period of uncertainty, but its long-term trajectory remains clear. Demand for clean electricity is expected to rise dramatically over the coming decades as economies electrify transport, industry and heating systems. Offshore wind, with its large-scale generation potential and strong capacity factors, will remain central to meeting that demand.
Delivering this expansion will require a robust global supply chain capable of installing and maintaining increasingly sophisticated offshore infrastructure. Companies able to combine technical capability, fleet scale and international experience will play a decisive role in shaping the industry’s next phase.
Cadeler’s recent contract wins, fleet expansion and regional growth illustrate how a focused strategy can deliver progress even in challenging market conditions. By investing in advanced vessels, expanding its geographic footprint and strengthening lifecycle services, the company continues to reinforce its position as one of the sector’s key enablers.
At a time when the offshore wind industry is confronting rising costs and policy uncertainty, Cadeler provides an example of what sustained ambition and operational excellence can achieve. Through continued investment and a commitment to delivering complex offshore projects safely and efficiently, the Danish company is helping ensure that offshore wind remains a cornerstone of the global energy transition.
