Mammoet at BHP Jansen headframe expansion: modular lift lessons for mine designers

30 Second Briefing
Mammoet has supported Ledcor in expanding the production and service headframes at BHP’s Jansen potash project in Saskatchewan, a greenfield mine targeting about 8.5 Mt/y of output from 2027 and expected to be among the world’s largest potash operations. The heavy-lift scope centred on installing large preassembled headframe modules and associated steelwork, reducing work at height and minimising crane reconfiguration on the constrained shaft collar area. For mine designers and contractors, the project shows how modular headframe construction and engineered lifting can compress schedules on deep-shaft developments in cold-climate greenfield sites.
Technical Brief
- Modularisation of headframe elements provides a template for safer deep-shaft headframe builds on future greenfield mines.
Our Take
With Jansen targeting 8.5 Mt/y of potash from 2027, it is set to sit at the top end of global greenfield potash capacity in our database, which likely raises the bar for shaft and headframe construction standards in Saskatchewan.
Mammoet’s role at Jansen follows its deployment of very high‑capacity lifting gear on UK infrastructure jobs such as the 4,200‑tonne Clifton railway bridge move and the incoming 2,500‑tonne LR12500‑1.0 crawler crane, signalling that BHP is leaning on contractors with a track record in ultra‑heavy, precision lifts for critical structures.
Among potash‑tagged mining pieces in our coverage, Canada—particularly Saskatchewan—features prominently, suggesting that execution performance at Jansen will be closely watched as a benchmark for future large‑scale potash developments in the province.
