diesel-power generation plant with heat recovery

US$272 million

CAPEX (Hatch's scope)

−50ºC

Arctic winter conditions

Challenges

Design facilities for Arctic conditions: ultra-low temperatures, drifting snow in wintertime and wet ground, permafrost conditions in summer
Manage the logistics of a remote air-and-barge-access location and a 10-week shipping season in mid-to-late summer
Supply all power and heat from an on-site, diesel-power generation plant
Operate in a remote, greenfield location with no existing support infrastructure of any kind

Solutions

Provided detailed engineering, procurement, and construction support services for the 8,500 tpd gold processing facilities and site infrastructure, including power-generation plant
Waste material from prestripping was used as bulk construction material for erecting dikes and for fill materials around the site
Eight major buildings were erected during summer so concrete and equipment installation could continue indoors during the harsh Arctic winter conditions
The power plant was designed to include a heat-recovery system, providing heat to the entire mine site complex

Highlights

More than 50,000 tonnes of material and equipment were mobilized to the site over a purpose-built, 115 km, all-weather road from Baker Lake
Equipment and construction materials were procured in time to be all shipped on barges during a short 10-week ice-free period in summertime
Our procurement and logistics strategy helped meet the construction schedule and improved working conditions for contractors through the winter
The diesel-fired power plant, heat-recovery, and heat-distribution systems that we designed were rigorous enough for Arctic conditions and resulted in cost savings and schedule improvements
