What Cadeler does

Cadeler A/S is a Copenhagen-based, publicly listed (NYSE: CDLR; Oslo: CADLR) pure-play offshore wind installation company that operates the world's largest fleet of heavy-lift jack-up vessels used to transport and install offshore wind turbine generators (WTGs) and foundations. Founded in 2008 (originally as Blue Ocean Ships A/S, later Swire Blue Ocean), the company became independent through a 2020 IPO and completed a strategic merger with Eneti Inc. in December 2023, consolidating the offshore wind installation market. As of 2025, Cadeler operates 10 vessels across four proprietary classes (O-class, P-class, M-class, A-class) with two additional A-class newbuilds (Wind Ace, Wind Apex) scheduled for delivery in 2026-2027, bringing the fleet to 12 vessels by mid-2027. Vessel specifications include crane capacities ranging from 800T to 3,300T+, deck spaces up to 5,600 m², and water-depth capabilities up to 65 meters, enabling installation of next-generation 15MW+ turbines and XXL monopile foundations.

The company generates revenue primarily through multi-year time charter contracts and project-based agreements with major offshore wind developers (Ørsted, RWE, ScottishPower Renewables, EnBW, Synera) and OEMs (Siemens Gamesa, Vestas), typically awarded via competitive tendering. Revenue streams include turbine installation (core), foundation transport and installation (T&I), and operations and maintenance (O&M) services through the Nexra platform launched in 2025. Cadeler reported FY2025 revenue of EUR 620 million (up 149% from EUR 249M in 2024), EBITDA of EUR 425 million, and net profit of EUR 280 million, supported by a EUR 2.8 billion order backlog. Operations span Europe (UK, Germany, Poland, Netherlands, Denmark, Belgium, Ireland), Asia-Pacific (Taiwan, Japan), and North America (USA), with offices in Copenhagen, Vejle, Norwich, Virginia Beach, Taipei, and Tokyo.

Revenue model

1. Offshore Wind Turbine Installation: Time charter contracts and project-based contracts for transporting and installing offshore wind turbine generators using Cadeler's fleet of jack-up vessels. Revenue is generated through day rates and lump-sum installation fees for specific project scopes.
2. Foundation Transport and Installation (T&I): Full-scope foundation transportation and installation services including monopiles and transition pieces. This represents a strategic expansion of services, exemplified by the Hornsea 3 project where Cadeler handles complete foundation T&I scope.
3. Operations and Maintenance (O&M) Services via Nexra: Dedicated O&M service platform providing maintenance, upgrade, and optimization services for offshore wind assets throughout their operational lifetime. Accounted for approximately one-fifth of group revenue in 2025.

Scale indicators15 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Van Oord: Dutch marine contractor with offshore wind installation capabilities, operating the Boreas and other jack-up vessels for transport and installation of foundations and turbines. Van Oord directly competes with Cadeler across European and US offshore wind projects with comparable fleet capabilities.
• Saipem: Italian offshore engineering and construction company with capabilities in offshore wind installation, particularly through its heavy-lift vessels and offshore operations. Saipem competes with Cadeler in the broader offshore installation market and is expanding into wind farm services.
• DEME: Belgian marine contractor operating the Orion and Innovation vessels for offshore wind installation. DEME competes directly with Cadeler in foundation T&I and turbine installation, particularly across the European offshore wind market and increasingly in the US.
• Boskalis: Dutch marine services and offshore contractor with growing offshore wind capabilities including cable installation, foundation T&I, and rock placement. Boskalis is expanding into vessel-based turbine installation, partially overlapping with Cadeler's full-scope T&I offering.
• Jan De Nul: Belgian marine contractor operating the Voltaire, a next-generation jack-up WTIV comparable to Cadeler's P-class vessels. Jan De Nul directly competes with Cadeler for offshore wind turbine installation contracts across Europe and increasingly in the US and Asia-Pacific.
• Heerema Marine Contractors: Dutch heavy-lift and offshore construction company with mega-vessels used for offshore installations. While primarily focused on oil & gas decommissioning and fixed platforms, Heerema has expanded into offshore wind foundation and substation installation, competing with Cadeler in foundation T&I.

Broad incumbents

• ZPMC: Shanghai-based heavy equipment manufacturer that builds offshore wind installation vessels and is developing its own fleet. ZPMC both competes with Cadeler as a fleet operator and is a key shipyard supplier, building some of Cadeler's A-class vessels at COSCO Qidong facilities.

Others

• Eneti (Seajacks): Acquired by Cadeler in December 2023. Seajacks' vessels (including Scylla and Zaratan, now part of Cadeler's fleet) historically competed directly in WTIV services. While now a subsidiary, it represents Cadeler's historical peer set and competitive context.

Regional players

• Penta-Ocean Construction: Japanese marine contractor with growing offshore wind installation capabilities focused on Asia-Pacific markets (Japan, Taiwan). Penta-Ocean operates installation vessels for Japanese offshore wind and partially competes with Cadeler in the APAC region.

Emerging players

• OHT (Offshore Heavy Transport): Norwegian-based heavy-lift vessel operator with semi-submersible heavy transport ships used for offshore wind foundation installation. OHT is expanding into the foundation T&I segment with new vessels like Alfa Lift, partially overlapping with Cadeler's A-class foundation work.
