A leveraged ship bet on offshore wind
- Cadeler is a pure-play contractor for offshore wind installation, not a power producer.
- The company has EUR 2.7B of backlog, which gives good revenue cover for the next few years.
- The fleet now has 10 operational vessels after deliveries of Wind Mover and Wind Pace.
- Nexra, its O&M arm, made up around 20% of 2025 revenue and adds steadier work.
- The main risk is simple: one broken vessel can hurt earnings fast.
Big backlog, big ships, big timing risk
Cadeler is tied to one big idea: the world needs more offshore wind farms, and those farms need rare ships that can install huge turbines and foundations at sea. The bull case is that Cadeler already has a strong seat in that market, with EUR 2.7B of backlog and major customers that need scarce vessel time.
Recent news has lowered one near-term worry. On Hornsea 3, a large UK offshore wind project, Cadeler has shown proof of concept. Management said the first full monopile was installed, with secondary parts commissioned and handed to the client, and eight monopiles were in the water as of the Q1 2026 call.
Cadeler is also trying to do more of the job itself. A EUR 175m private placement is meant to help fund two proposed T-class newbuilds and a scour protection vessel, which places rock around foundations to stop seabed erosion. If this works, Cadeler can sell a more complete foundation package and reduce some project handoff risk.
The bear case is still real. This is a small fleet business with large assets, so downtime matters a lot. The offshore wind market could still be soft in 2028, even though Cadeler now says 2027 is fully booked and has a preferred supplier agreement for a large 2028 foundation project.
Paid when rare ships work
Cadeler makes money by chartering specialized jack-up vessels. A jack-up vessel lowers legs to the seabed, lifts itself above the water, and uses heavy cranes to install wind turbine generators or foundations.
Most revenue comes from transportation and installation work, often called T&I. These jobs can be large and valuable, but they are tied to project timing. If a developer delays a wind farm, Cadeler may have to move vessel plans or wait for work to start.
Nexra is the newer O&M business, short for operations and maintenance. This work keeps wind farms running after they are built. Management said O&M services were around one fifth of 2025 revenue, which matters because it can smooth out some of the lumpiness in big installation projects.
The model breaks when ships are idle, late, or damaged. A vessel that is not working still costs money. A month of repairs can matter, as shown by Wind Scylla's June 2025 leg damage.
The fleet is the product
T&I jack-up fleet
Cadeler operates 10 offshore jack-up installation vessels across A-Class, P-Class, M-Class, O-Class, Wind Keeper, Wind Scylla, and Wind Zaratan. These ships install turbines and foundations for wind farm developers.
A-Class newbuilds
Two more A-Class vessels are scheduled for delivery in Q3 2026 and H1 2027. They add capacity, but they also bring yard and delivery risk.
Proposed T-class newbuilds
Cadeler is moving forward with two proposed T-class vessels after raising EUR 175m in a private placement. These vessels are aimed at future turbine installation demand.
Scour protection vessel
The planned rock dumping vessel would place rock around offshore foundations to protect them from seabed erosion. Cadeler wants to use it inside its own foundation projects and also sell the service to clients.
Nexra O&M
Nexra serves the operations and maintenance market. Wind Zaratan is being used as a dedicated O&M asset, and Wind Scylla is expected to shift toward this work over time.
One company, two revenue pools
Cadeler reports as one operating segment in its filings, but management gave a 2025 service mix on the Q4 2025 call. O&M was around one fifth of 2025 revenue, with the rest mainly T&I.
What could break the case
Single-vessel downtime
High impact · Medium oddsCadeler has only a small number of very expensive working vessels. If one ship breaks, revenue can fall while costs keep running. Wind Scylla showed this risk in June 2025 when leg damage required about one month of urgent repairs.
Hornsea 3 execution slips
High impact · Medium oddsHornsea 3 is a major foundation job and has already had timing noise from client requirement changes. Q1 2026 proof of concept lowered the near-term worry, but the project still needs smooth repeat execution. Problems could push revenue into later periods or hurt customer confidence.
COSCO yard and sanctions risk
Medium impact · Medium oddsSome newbuild exposure runs through COSCO-related Chinese yards. The 2024 20-F flagged the U.S. Department of Defense designation of certain COSCO affiliates as Chinese military companies. Cadeler has not said this has stopped deliveries, but extra U.S. or allied measures could disrupt timing or financing.
2028 market gap returns
Medium impact · Medium oddsThe worry about weaker work in late 2027 and 2028 has eased for Cadeler. Management now says 2027 is fully booked and 2028 looks better after a preferred supplier agreement. Still, if developers push offshore wind projects further out, Cadeler could face lower day rates or idle time.
Nexra fails to hold momentum
Medium impact · Low oddsNexra helps Cadeler add steadier O&M work, and it made up around 20% of 2025 revenue. But this business still needs the right mix of long-term and spot contracts. If pricing or vessel use weakens, it may not smooth earnings as hoped.
In one breath
What does Cadeler A/S do?
Cadeler installs offshore wind turbines and foundations using large jack-up vessels. It is a contractor for wind farm builders, not a utility that sells electricity.
Why does Cadeler's backlog matter?
Backlog is contracted work that has not yet turned into revenue. Cadeler's EUR 2.7B backlog gives better visibility, but the money still depends on projects starting and vessels performing.
What is Nexra?
Nexra is Cadeler's operations and maintenance division. It focuses on keeping wind farms running after construction, which can be steadier than one-off installation projects.
What is Cadeler's biggest risk?
The biggest company-specific risk is vessel downtime. With a small fleet, damage to one ship can quickly affect revenue, costs, and project schedules.
