Mammoet has supported HEBO in the careful transport of the historic IJsselkogge, a 15th century shipwreck, relocating the preserved vessel from Lelystad to Zwartsluis. The operation combined conventional trailers, a prime mover, and barge transport, ensuring the fragile historic structure was moved safely for restoration and future public display.
Historic Vessel Relocated for Restoration and Exhibition
Mammoet recently assisted HEBO in transporting the IJsselkogge, a rare 15th century shipwreck, from Lelystad to Zwartsluis in the Netherlands. The operation marked a significant milestone in the preservation of the historic vessel, which will now undergo restoration before being placed on public exhibition in Zwartsluis.
The IJsselkogge was discovered in 2009 and initially transported to Lelystad, where it was stabilized and preserved. With preservation work complete, the vessel was ready for relocation to its long-term restoration and exhibition site.
Transport Planning for a Fragile Historic Structure
Transporting a centuries-old shipwreck presents unique challenges, requiring careful planning to protect the integrity of the structure throughout the move. Unlike modern vessels or industrial components, the IJsselkogge’s preserved remains required controlled handling, stable support, and minimized movement during transport.
Mammoet supported HEBO by providing expertise in heavy transport logistics and execution, ensuring that each stage of the relocation was completed safely and in accordance with preservation requirements.
Conventional Trailers and Prime Mover Used for Controlled Movement
The historic wreckage was loaded onto conventional trailers, connected to a prime mover, allowing for controlled positioning and movement during loading and unloading operations. This transport configuration offered stability and precise maneuverability, which was critical given the vessel’s age and fragile condition.
Once secured, the load was transferred onto a barge in Lelystad, enabling waterborne transport to Zwartsluis. Using a barge minimized handling and vibration, reducing risk during the longer transport leg.
Barge Transport and Final Positioning in Zwartsluis
Upon arrival in Zwartsluis, the vessel was carefully driven off the barge using the same trailer and prime mover setup. This roll-on/roll-off approach reduced the need for additional lifting or handling, further protecting the historic structure.
The IJsselkogge was then positioned at its designated location, where restoration work will continue ahead of its future exhibition. The successful completion of the move highlights how modern heavy transport techniques can be adapted for sensitive heritage projects.
Combining Engineering Expertise with Cultural Preservation
The relocation of the IJsselkogge demonstrates the role of heavy transport specialists in supporting cultural and historical preservation. By combining engineering expertise, suitable equipment selection, and careful execution, Mammoet and HEBO enabled the safe movement of a unique archaeological asset.
