Description:

LINDSAYCA, with its other 3 partners (Vepica, Tordec & Pyecsa), provided review of basic Engineering and developed the Detail Engineering of the project. Such activities where executed in 3 different Engineering Centers around the globe.

More than 95 new equipment (including major Fractionation Columns and Skids) were designed and procured to replace or optimized the petrochemical facility. All Balance of Plant Activities were fabricated off-site to maximize time of delivery. The installation of most of the equipment and BOP spools was performed while the plant was in operation.

More than 45 days of Shutdown activities were achieved with an excellent safety performance and schedule management. More than 900 workers worked during 2 shifts to complete all activities.
