What we do

We support projects designed to ensure long-term reliable operation and meet stringent specifications related to hazardous areas.


ONEC offers services for refineries, petrochemical plants, and cGMP facilities. Our past projects include detailed engineering of a sulphur degasser, API pump installations, reactor installations, piping for heavy oil product lines, and maintenance for plant shut-downs. We plan and implement projects balancing industry standards, client project requirements, and efficiency, without ever compromising safety or the environment.
