30 TPD Micro LNG Plant and LNG mine truck conversions including customer LNG tanks.
Goldfields Ghana Limited, in cooperation with Caterpillar, is to convert up to 60 x Caterpillar Mine Haul trucks from Diesel fuel to LNG/Diesel Dynamic Gas blending (DGB) systems. EPCM is the technical partner conducting all engineering, procurement and construction works.
Goldfields required an Interim LNG supply solution to trail 9 Trucks as a trail, and thereafter 9 trucks will be converted per year until 5 trucks have been converted in 2024. The projected trucks to run on LNG will be 60 by 2031. EPCM is to supply a sustainable Interim and Long-term LNG solution to the mine by means of LNG import during interim phases and a 30 TPD Micro-LNG plant for the long-term supply (modular expansion capability to 50 TPD).
