30-Second Takeaway
Liebherr has been awarded a contract to supply a BOS 45000 heavy-lift offshore crane to South Korea’s Eunsung O&C Co., Ltd. The crane, offering up to 1,200 tonnes lifting capacity at 22 metres and a maximum boom length of 117 metres, will be installed on the jack-up barge VEGA, scheduled to enter service in 2029. The project strengthens Liebherr’s position in the growing Asian offshore wind market and reinforces the BOS series’ legacy in offshore installation and maintenance operations.
BOS 45000 Heavy-Lift Offshore Crane for South Korea
Liebherr has successfully concluded an agreement for the delivery of one Board Offshore Crane BOS 45000 to Eunsung O&C Co., Ltd., headquartered in South Korea.
The crane will be installed on the jack-up barge VEGA, which will operate in offshore wind turbine installation and maintenance campaigns throughout Asian waters. Entry into service is planned for 2029.
With a lifting capacity of up to 1,200 tonnes at a 22-metre radius and a maximum boom length of 117 metres, the BOS 45000 is engineered to meet both current and future requirements in the rapidly evolving offshore wind sector.
Purpose-Built for Offshore Wind Installation
The BOS 45000 is designed specifically for heavy offshore construction scopes, including:
Installation of large offshore wind turbine components
Nacelle and tower section lifting
Foundation and transition piece handling
Major component replacement
Life-extension maintenance work
As offshore wind turbines increase in size and output capacity, installation vessels require cranes capable of handling heavier loads at greater heights while maintaining precise load control. The BOS 45000 is configured to meet these operational demands with robust structural engineering and optimised boom geometry.
Installed on the jack-up barge VEGA, the crane will provide the lifting power and operational precision required for next-generation offshore wind projects across Asia.
Proven Offshore Crane Architecture
The Liebherr BOS series has been a cornerstone of offshore lifting since 1975, with more than 500 units delivered worldwide.
The BOS 45000 retains the series’ hallmark features:
A-frame design with lattice boom
Wide walkways for safe crew access
Clearly routed service points
Smooth luffing supported by integrated A-frame architecture
Fast auxiliary hoists for secondary lifting operations
The lattice boom configuration allows long outreach with stable and accurate load handling essential for offshore lifts subject to vessel motion and environmental forces.
Armin Seidel, Area Sales Manager at Liebherr Rostock, stated:
“This crane concept has consistently proven its reliability and technical strength in offshore operations. For decades, this crane family has stood for dependable offshore lifting solutions. The new BOS 45000 continues this direction and shows how proven engineering can support the next generation of offshore wind projects.”
Strategic Partner: Eunsung O&C
Founded in 1989, Eunsung O&C Co., Ltd. is recognised for its expertise in ground improvement, foundation engineering and complex onshore and offshore infrastructure projects.
The company brings significant offshore project discipline to the VEGA development.
Mr. Hee-Sung Eun, President of Eunsung O&C, commented:
“At Eunsung O&C, we take pride in delivering solutions that precisely meet our clients’ needs at sea. Building on our experience from major international projects, we look forward to working with Liebherr to integrate the BOS 45000 on VEGA with the highest standards of safety, quality and reliability.”
The crane construction phase is scheduled from summer 2026 through 2028, with installation and integration on VEGA targeted for completion by mid-2029.
Service Excellence and Long-Term Support
Liebherr and Eunsung O&C have an established working relationship. Most recently, Liebherr completed a Transform project in Suncheon, South Korea, extending the boom of an Eunsung BOS 14000 by 24 metres to a total of 84 metres. The project was delivered in five weeks by an international service team.
This demonstrates Liebherr’s capability in:
Custom crane modifications
International service coordination
Rapid engineering deployment
Lifecycle performance upgrades
For the VEGA project, Liebherr South Korea will oversee installation, commissioning and testing (ICT), supported by Liebherr’s global service network across more than fifty subsidiaries worldwide.
Eddie Park, Divisional Manager at Liebherr South Korea, stated:
“As the project moves forward, our focus in South Korea will be to ensure a smooth ICT process and to provide comprehensive lifecycle support.”
This global service infrastructure ensures short response times, inspection programmes, tailored maintenance plans and ongoing technical support throughout the crane’s operational life.
Strengthening Offshore Wind Capabilities in Asia
Asia’s offshore wind market continues to expand rapidly, with increasing turbine capacities driving demand for high-capacity installation vessels and heavy-lift cranes.
The delivery of the BOS 45000 offshore crane positions Liebherr and Eunsung O&C to participate in large-scale offshore wind developments across South Korea and the wider Asian region.
By combining heavy-lift capability, long boom reach and integrated lifecycle support, the project reinforces Liebherr’s long-standing reputation in the offshore sector while supporting the energy transition through reliable offshore wind infrastructure.
