Koniambo Nickel - New Caledonia

Koniambo Nickel - New Caledonia

Located in the north of New Caledonia, the Koniambo plant is a world-class industrial complex that, when it reaches full production capacity, will make New Caledonia one of the world’s largest nickel producers.
Since 2010, we have brought in many employees to this project, in the following areas: support functions (EHS, contract management, purchasing, planning, doc control), site supervision (E&I, pipework, mechanics, maintenance, material management, civil engineering), and project management.

Antwerp Refinery: OPTARA project - Belgium

Antwerp Refinery: OPTARA project - Belgium

Total has decided to invest €1bn on this revamping project.  This major investment has made it possible to transform OPTARA (Optimisation of the Amsterdam - Rotterdam - Antwerp area) into a new refining complex with production that now meets market needs. 
Between 2013 and 2018, several ATYX experts worked mainly in support functions: cost control, planning, contract and claims management, and site supervision: piping, quality, E&I, site management.
