Sarens Sets European Benchmark with Record-Breaking 1,850-Tonne Lift Using Liebherr LR 12500-1.0 at Wergeland Base

Sarens completes a record-breaking offshore decommissioning project at Wergeland Base, lifting 1,850-tonne marine footings using a single LR 12500-1.0 crawler crane and advanced SPMT logistics.

30-Second Takeaway Sarens has completed a landmark offshore decommissioning project at Wergeland Base in Norway, executing an exceptionally rare 1,850-tonne lift using a single Liebherr LR 12500-1.0 crawler crane. The operation involved lifting massive marine footings from the water, transporting them by SPMTs, and re-immersing them for dismantling. Achieved under extreme weather conditions, the project highlights Sarens’ ability to deliver record-setting heavy lifts, cost-efficient execution, and sustainable decommissioning solutions at the highest level of complexity. Sarens completes landmark decommissioning project at Wergeland Base A Record-Breaking Achievement Sarens has successfully completed a landmark decommissioning project at the Wergeland Base in Gulen, Norway, which involved lifting, transporting, and re-immersing four massive footings. This project demonstrated not only Sarens' engineering expertise but also its ability to perform record-breaking lifts under challenging conditions. The project’s highlight was the use of Sarens' LR12500-1.0 crawler crane to lift each footing, which weighed an extraordinary 1850 tonnes. Lifting such a weight with a single crawler crane is exceptionally rare in Europe and may be a record-breaking achievement. While SGC cranes can handle such lifts with ease, accomplishing this with a crawler crane emphasizes Sarens' capability to manage some of the world's heaviest loads. Tailored Solutions and Precision Execution Commissioned by Wergeland, the project involved: • Lifting the 25m-high, 27m-wide footings out of the water. • Transporting them to a quay using Self-Propelled Modular Transporters (SPMTs). • Re-immersing the footings. Sarens completes landmark decommissioning project at Wergeland Base Sarens was chosen for its cost-effective and highly specialized solution. By extending the contract for the LR12500-1.0 crane, which was already deployed at the site, Sarens ensured seamless execution while minimizing costs for the client. Technical Details The operation required: • The LR12500-1.0 crane configured with an 80m main boom, a 35m superlift radius, and 1,240 tonnes of superlift weight. • SPMTs with multiple axle lines for precise transport. • A 2000-tonne shackle, a standard but exceptionally large component, designed to meet the project's unique demands. Challenges and Triumphs The execution of this project presented several challenges. The footings, floating at sea, required rigging during record-breaking rainfall, which tested the team's resolve. Despite these obstacles, Sarens' experienced team, led by Project Manager Willem Ditmer and Project Engineer Wim de Keersmaecker, completed the operation on schedule and without compromising safety. Sustainability in Action As a decommissioning initiative, the project reflects Sarens' commitment to sustainability. The footings were scrapped and recycled, supporting greener practices while contributing to the local economy. A Milestone for the Team The capabilities of Wergeland Base were further validated by this milestone achievement, showcasing it as an ideal site for high-complexity operations. The successful completion of this complex and record-breaking lift serves as a testament to Sarens' ingenuity and dedication. It marks a significant milestone for the operators and reinforces Sarens' position as a leader in heavy lifting and transport solutions.

The project involved lifting 1,850-tonne offshore footings with a single crawler crane, a feat that is extremely rare in Europe. Such weights are typically handled by ring cranes or floating heavy-lift vessels, making this operation potentially record-breaking. Which crane was used for the heavy lifts? Sarens deployed a Liebherr LR 12500-1.0 crawler crane, one of the most powerful land-based crawler cranes in the world, specifically configured to handle ultra-heavy offshore components. How was the LR 12500-1.0 configured for the lift? The crane was set up with: 80-metre main boom 35-metre superlift radius 1,240 tonnes of superlift counterweight This configuration enabled precise control and stability for lifting floating loads directly from the water. How were the footings transported after lifting? After being lifted from the water, the 25-metre-high footings were transported across the quay using Self-Propelled Modular Transporters (SPMTs) with multiple axle lines for load distribution and maneuverability. What role did sustainability play in the project? As part of a decommissioning initiative, the footings were scrapped and recycled, reducing environmental impact and supporting circular-economy practices while benefiting the local supply chain.
