About Cadeler

Cadeler is a hybrid between a shipping and a construction company operating in the offshore wind industry. We specialize in the transport and installation of foundations and offshore wind turbines.

The company was established in 2008 under the name Blue Ocean Ships. In 2010, it changed its name to Swire Blue Ocean while operating as part of the Swire Group. In October 2020, the company demerged from Swire Group and underwent an IPO to become an independent entity and has operated under the Cadeler brand ever since.

We have installed over 650 offshore wind turbines and more than 500 foundations - equivalent to wind energy powering more than 8 million European households.  Furthermore, we offer a wide range of offshore services incl. O&M, T&I and other marine and engineering operations with a strong focus on safety and the environment.  

Cadeler is on a clear mission to facilitate the world’s transition to a more sustainable planet built on renewable energy by being the key supplier in the development of offshore wind energy. Our experience as provider of high-quality offshore wind support services, combined with innovative vessel design, allows our company to deliver premium services to the industry.  By striving for excellence in everything we do - from safety, recruitment and training, state-of-the-art vessel design, maintenance to management, Cadeler is able to provide the best in class service to our customers.

Cadeler is headquartered in Copenhagen, Denmark and has offices in Vejle, Denmark and Taipei, Taiwan.


Cadeler operates currently two highly efficient Windfarm Installation Vessels (WIVs), Wind Orca and Wind Osprey. In addition to offshore wind farm installation, these vessels are very well suited for maintenance and decommissioning tasks. Equipped with a main crane with a lifting capacity of 1,200 metric tons 4,300m2 main deck area, an auxiliary crane, and six legs with a length of 105m each, our vessels are designed to meet the needs of the offshore industry. Safety and reliability are two key points of focus in the WIV design. The WIVs are fitted with six legs to increase stability during jacking operations and a redundant diesel electric propulsion system to increase capabilities and minimize downtime. The wind turbines are sizing up, and so are the demands for even larger cranes with higher specifications. By the beginning of 2024, both our O-class vessels will be ready to operate with new improved cranes capable of handling the next generation of turbines.

Cadeler is on a growth journey  in terms of size and fleet. During the next few years, Cadeler's fleet will grow thanks to the addition of two P-class and two A-class vessels thereby having the largest fleet in the wind industry that will install the next generation of offshore wind turbines.

We are ready to enable the world's transition to a future built on offshore renewable energies. 



Cadeler was established in 2008 as Blue Ocean Ships A/S. The Company's initial success was kickstarted by an entrepreneurial spirit and supported by an innovative design for a new class of windfarm installation vessels. In 2010, we were acquired by the Swire Group and operated with Swire Pacific Offshore Operations (Pte) Ltd. as our direct parent company for a decade. Our vessels were delivered in late 2012 and early 2013; after which, we achieved the completion of our first offshore wind installation projects before the end of 2013. During our time with Swire, we benefitted from working within a group characterized by 200+ years of professional experience, and our organisation's culture matured with a focus on the group's core values: Integrity, Endeavour, Excellence, Humility, Teamwork and Continuity. 

In 2020, we ended the chapter as a subsidiary company of Swire Pacific Offshore. The decision was influenced by the trajectory of growth in the offshore wind industry and our need to invest in solutions to enable this growth. Our solution was to establish an independent company in order to support our goal of investing in assets vital to ensuring the supply chain's ability to keep pace with the worldwide connection of offshore wind capacity.
