FS/FEED(Feasibility Study/Front-End Engineering Design)

JPI fully understands client's requirements and project plans and gives due consideration to plants' construction costs, safety, operating costs and environmental preservation from an overall perspective, thereby working out highly efficient and optimum environmental process flow, and prepares FEED package accordingly.


Based on FEED, JPI starts with basic engineering on process with consideration given to work schedule, procurement, construction, operation and maintenance, followed by detailed design to be developed using expertise and technologies on piping, rotating equipment, static equipment, combustion equipment, electrical, instrumentation & control, building and civil, thereby working out the optimum plant that is to be constructed at minimum costs.
Furthermore, JPI provides plant design complying with client's requirements for operation, maintenance and safety by conducting appropriate studies such as 3D model review, HAZOP, HAZID and SIL verification as needed.

Construction & Commissioning

Under the project manager, the construction manager, who is responsible for the operation of his or her construction site, prepares detailed construction plans. During the construction stage, discipline engineers involved in engineering are stationed at the site, as required, according to work progress, to supervise to see that the work is being properly conducted as engineered by them and give instructions accordingly, thus ensuring that their instructions are properly reflected in the work at the site.
Furthermore, JPI executes commissioning seamlessly upon mechanical completion, supporting the client for smooth start-up of the plant.
