30-Second Takeaway
Mammoet has successfully completed the replacement of a 2,090-tonne headframe at BHP’s Jansen potash mine in Saskatchewan. Using modular construction, SPMTs, and crawler cranes, the project was delivered efficiently despite logistical challenges. The upgrade supports the mine’s planned production of 8.5 million tonnes per year, with precision installation playing a critical role in the operation’s success.
Mammoet Headframe Replacement Jansen Mine
Mammoet has supported the rapid replacement of a major headframe at BHP’s Jansen potash mine in Canada, utilising advanced modular construction and heavy transport solutions to streamline the complex operation.
Located in Saskatchewan, the Jansen project is set to become one of the world’s largest potash mines, with planned production capacity of 8.5 million tonnes per year.
Working alongside Ledcor, Mammoet’s scope included removing the lower section of an existing headframe and installing a significantly larger replacement structure to increase mining capacity.
Modular Construction Reduces Project Timeline
The new headframe, weighing 2,090 tonnes, was delivered in prefabricated sections from Alberta and assembled on site.
By adopting a modular construction approach, the project team enabled parallel workstreams, reducing both on-site labour requirements and overall project duration. This method allowed for greater efficiency while maintaining strict safety and quality standards.
Heavy Transport Challenges Across Rural Routes
Transporting oversized components to site required detailed logistical planning, particularly due to rural access routes, limited staging areas, and challenging ground conditions.
To address these challenges, extensive ground testing was conducted, and more than 400 crane mats were deployed to ensure stability throughout the operation. These measures were critical in supporting the safe movement and positioning of heavy loads.
SPMTs and Crawler Cranes Drive Heavy Lifting Operations
Heavy lifting activities were carried out using self-propelled modular transporters (SPMTs) and crawler cranes, including the LR1300 and LR1500.
In addition, a strand jack system was used to install a 60-ton staircase tower within the structure, demonstrating the combination of lifting technologies required to execute complex installation tasks.
Precision Installation with Laser Alignment
The final installation phase required extremely precise positioning of the new headframe within tight tolerances. Laser guidance systems were used to ensure accurate alignment, as even minor deviations could have impacted the integrity and functionality of the structure.
“This was a very precise maneuver,”
said Mike de Wilde, Project Manager at Mammoet.
“Every deviation could have caused serious issues during installation.”
Supporting Future Potash Production Capacity
The successful installation of the new headframe marks a significant milestone for the Jansen project, which is expected to play a major role in global potash supply.
By combining modular construction, advanced transport methods, and precision engineering, Mammoet has contributed to improving efficiency and scalability at one of the world’s most important upcoming mining operations.
