Ghana Goldfields Micro LNG Caterpillar Conversion Project

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).
