HOW YUNTIAN YTM-SB1600 MARINE STIFF BOOM CRANE SUPPORTED NEXT-GENERATION OFFSHORE WIND INSTALLATION
Background
As offshore wind turbines continue to increase in size, installation contractors are facing growing lifting challenges. A European offshore wind contractor preparing for a new North Sea project needed a crane capable of handling nacelles weighing more than 700 tonnes while maintaining stable load control in offshore conditions.
Their existing crane fleet had performed well on previous projects, but larger turbine components and stricter installation requirements called for a more reliable heavy-lift solution.
The Challenge
Existing Crane Designs Reached Their Limits
1.The contractor initially evaluated larger telescopic and knuckle boom cranes. However, engineers identified concerns about boom deflection at long outreach distances and the increased maintenance demands associated with complex hydraulic systems.
2.For offshore turbine installation, precise load control is critical. Even small movements caused by vessel motion can affect positioning accuracy during nacelle installation.
Downtime Was Costly
With vessel operating costs exceeding €180,000 per day, reliability became a key factor in the crane selection process. Unplanned maintenance or equipment failure could quickly impact installation schedules and project profitability.
The Solution
YTM-SB1600 Marine Stiff Boom Crane
1.After technical evaluation, the contractor selected the Yuntian YTM-SB1600 Marine Stiff Boom Crane.
2.Featuring a rigid single-piece boom and a lifting capacity of up to 1,600 tonnes, the crane provided the stability required for heavy offshore lifts. Unlike telescopic or articulated designs, the stiff boom structure minimizes flex and delivers more predictable load control.
Active Heave Compensation
1.The crane was equipped with an Active Heave Compensation (AHC) system that continuously adjusts winch movement to compensate for vessel motion.
2.This allowed installation crews to maintain accurate load positioning during offshore lifting operations, even in challenging North Sea conditions.
Built for Offshore Environments
To withstand long-term exposure to saltwater and harsh weather, the crane was protected with a marine-grade corrosion protection system and corrosion-resistant hydraulic components.
Results
Reduced Maintenance Requirements
1.The simplified stiff boom design eliminated many components commonly found on telescopic cranes, including extension cylinders and wear-pad assemblies.
2.As a result, the contractor reported approximately 40% fewer scheduled maintenance hours compared with previous crane systems.
Improved Reliability
1.During the installation campaign, the YTM-SB1600 delivered consistent performance with no crane-related operational interruptions.
2.The reduction in maintenance requirements helped maximize vessel availability and reduce operational risk throughout the project.
Successful Project Delivery
1.The crane provided the lifting capacity, stability, and reliability needed for next-generation offshore wind installation.
2.The project was completed within the planned schedule, with all major lifts carried out safely and efficiently. Following the successful deployment, the contractor identified the YTM-SB1600 platform as a suitable solution for future offshore wind projects involving larger turbine capacities.
Conclusion
1.For offshore wind developers and installation contractors, crane reliability is just as important as lifting capacity.
2.By combining a robust stiff boom structure, Active Heave Compensation technology, and offshore-grade durability, the Yuntian YTM-SB1600 helped support efficient heavy-lift operations while reducing maintenance demands and operational risk.
3.As offshore turbines continue to grow in size, dependable heavy-lift solutions like the YTM-SB1600 will play an increasingly important role in the success of future wind energy projects.
