Plant Modifications/Upgrades

LNG Services from Concept to Completion

CHI performs upgrades and modifications for LNG plant process systems as well as ancillary systems including electrical systems, control systems, emergency generators, fire protection systems, instrument air or nitrogen systems and other crucial components of LNG plants and facilities. Integration of new technology, capacity increase or new processes into existing facilities has been mastered by our design and field teams. There is no substitute for experience when it comes to meeting the challenges inherent in civil, mechanical, electrical and controls assimilation of new and existing facilities.

Our stem to stern approach for upgrading and modifying LNG plants includes:

  • Feasibility studies
  • Permitting
  • Detailed design
  • Procurement
  • Construction
  • Start-up and commissioning
  • Operator training
  • O&M manual revision or generation
  • Downstream maintenance
  • Arc flash/power flow studies

We’ve delivered our comprehensive engineering, procurement and construction services to more than 95 U.S. sited LNG plants. With more than 35 years of experience, we are highly effective at utilizing our extensive knowledge of best practices, facility components, logistics and the latest technologies to execute LNG plant upgrades and modifications that solve our clients’ complex challenges.

 

Plant Modification

From storage to liquefaction, to vaporization and truck loading, there isn’t a component or system of a satellite or full-scale LNG peak shaver plant that CHI hasn’t provided or improved.

Q. When should upgrades to plant ancillary systems be considered?

A. Replacement or upgrades to ancillary systems should be considered based on the age/performance of the equipment and whenever a larger plant facility is upgraded. This ensures that systems such as instrument air, power, controls and fire protection have adequate capacity to serve any new equipment/facilities.

Q. Can an LNG plant stay in operation while upgrades are performed?

A. With proper project planning, critical plant systems are maintained in service with limited or no downtime. Major process system upgrades are scheduled for implementation during seasonal downtime and are managed to be complete including commissioning and training prior to the next operating season.
