CNBM undertook NRCC EPC project of Line I  in Saudi Arabia in 2006. After the construction complete, CNBM production & plant service team carried out commissioning for Line I and then rendered a two-year overall O&M service, which also include training services for local staff. Owing to CNBM’s outstanding performance, the client was hoping to continue the service, thus CNBM performed joint production for Line I later along with the client’s personnel. In the meanwhile, CNBM assumed EPC project of Line II from 2010 to 2012. When the project was done, the client, with appreciation of CNBM’s reliable, integrated, professional and efficient service, asked CNBM to provide similar plant service to Line II as we had provided to Line I. Now, the two companies are seeking further cooperation in plant optimization to reduce energy consumption and increase efficiency.
