INEOS Oligomers

Organizational Context and Job Purpose

Organizational Context:

INEOS is a global manufacturer of petrochemicals, speciality chemicals and oil products. Comprising 36 individual businesses, we operate 194 facilities in 29 countries throughout the world. 

With LAO manufacturing facilities in USA, Canada and Belgium, INEOS Oligomers is one of the largest merchant suppliers of Linear Alpha Olefins (LAO), which are used as co-monomers in polyethylene manufacture as well as in surfactants, lubricants and oil drilling fluids. Our technology has a clear competitive advantage over our competitors. Further developments of the technology are planned to be an integral part of this project.

Our markets are growing worldwide. Through selective investments in new assets and new technology, we intend to capture this growth to develop our business and grow with our customers. As part of this exciting growth strategy, we are investing in a new world scale production facility located in the Middle East. The plant capacity will be 420 KTA and is planned to come on-line in 2027.

Purpose of the job:

The Mechanical Discipline Engineer, under the direction of the Discipline Engineering Manager, will provide mechanical expertise related to static and rotating equipment within the design of the plant and associated “offsites” facilities.  This includes, but is not limited to, reviewing specifications and standards, solving technical or complex mechanical problems, supporting and documenting lessons learned, interacting with engineering and construction contractors, and acting as key member of the owner’s project team.  The Mechanical Discipline Engineer will ensure mechanical integrity of the design of the plant and the associated offsites, and will align and coordinate with Instrument, Electrical and Piping disciplines within the project team and with the relevant disciplines within the PMT and FEED/EPC contractors to maintain design and construction consistency and reliability.
