Project Overview

The Client’s naphtha export pump is a single mechanical seal centrifugal pump that has been in continuous service for approximately 45 years. This pump exports naphtha and diluent from tanks to pipelines. These exports are hydraulically limited to 15kbbl/day. Diluent export demand was expected to exceed 15kbbl/day. The projects mandate was to rework the discharge piping to remove the hydraulic restriction.

Discharge Piping Upgrade main

Detailed Engineering

The Client has the capacity to store diluent in tanks for approximately 72 hours before refinery operations are affected. To mitigate the concern, 80% of the piping was routed so that it could be installed while the pump was in operation. A 24-hr pump outage was taken to make the final tie ins.

Scope of Work

Rally worked closely with Client operations and maintenance teams to get alignment on the execution plan. Rally established an aggressive schedule for the engineering of the construction work package.
Rally participated in the pre-start-up safety review (PSSR), which included reviewing the physical installation of the piping, ensuring that it was installed per the engineered drawings.
