MHI Compressor International Corporation, known as MCO I, has been selected to provide critical turbomachinery for Shintech’s PEP 2 project in Plaquemine, Louisiana.
The award gives the Mitsubishi Heavy Industries compressor business a central role in one of the Gulf Coast’s notable new petrochemical investments.
The planned facility will have annual ethylene production capacity of 625 KTA.
Operations are expected to begin in 2030, giving the project a multiyear path through engineering, equipment delivery, construction, installation, commissioning, and startup.
For MCO I, the selection deepens an already substantial presence along the U.S. Gulf Coast.
That corridor remains one of the most important concentrations of refining, petrochemical processing, feedstock infrastructure, and heavy industrial investment in North America.
Shintech plans to use all ethylene produced at the new plant within its own vinyl chloride monomer manufacturing operations.
The arrangement is intended to strengthen integrated production by connecting the new ethylene capacity directly with an established downstream manufacturing requirement.
That captive supply strategy can provide greater operational alignment across Shintech’s production chain.
It also makes dependable turbomachinery especially important, since compressor availability, mechanical integrity, efficiency, and process stability can directly influence output across interconnected plant operations.
MCO I will execute the equipment scope by combining expertise from MCO Hiroshima and MCO I Houston.
The international collaboration brings together manufacturing and engineering capabilities in Japan with regional project experience and customer support resources in the United States.
The companies did not disclose the financial value of the award or provide a detailed equipment list. Even so, describing the machinery as critical indicates that the package will support essential process duties within the ethylene production complex.
Ethylene facilities place demanding expectations on rotating equipment because process continuity depends on reliable compression across severe and carefully controlled operating conditions.
Equipment selection must account for efficiency, availability, maintainability, vibration behavior, process integration, and dependable operation over extended production campaigns.
For the supplier, the contract is more than another equipment order. It expands MCO I’s role in the ethylene market while adding a significant reference project to its growing North American portfolio.
The project also represents the second U.S. plant for this end user where MCO I has been selected to supply critical turbomachinery for ethylene production.
Repeat selection carries particular weight in major process projects, where purchasing decisions reflect technical confidence, execution history, service capability, and long term operating expectations.
Michael McCurry, manager, new unit business sales, said, “This project represents a major milestone, as it marks the second U.S. based plant with this end user where MCO I has been entrusted to provide critical turbomachinery solutions for ethylene production. We appreciate the confidence placed in our team and look forward to supporting a project that will help the growth of Shintech.”
The Plaquemine development arrives as Gulf Coast producers continue to pursue integration and scale in petrochemical manufacturing.
Access to industrial infrastructure, skilled labor, logistics networks, and established processing operations has kept the region central to large capital projects.
A 2030 operating target means execution discipline will be vital throughout the project schedule.
Turbomachinery packages often require close coordination among process licensors, engineering contractors, plant owners, equipment manufacturers, and construction teams long before machinery reaches the site.
MCO Hiroshima and MCO I Houston will need to align technical design, manufacturing, quality control, testing, logistics, installation support, and commissioning preparation.
Such coordination is particularly important for critical rotating equipment, where decisions made during engineering can shape reliability and serviceability for decades.
For Shintech, the new plant is designed to reinforce control over a fundamental raw material used in its vinyl chloride monomer business.
For MCO I, the selection delivers a prominent Gulf Coast assignment and another opportunity to prove its capabilities in demanding, large scale ethylene service.
