Expansion of Tank Terminal had 3 primary requirements:
• Increase capacity of shipped bitumen (dilbit) by over fifty percent (50%) from current design flow rate of 400 kbpd to 600 kpbd.
• High pressure pumping via two new 700 hp API BB2 horizontal pumps; custody transfer metering and quality assurance of shipped dilbit product including facilities for portable meter proving.
• Custody transfer metering and quality assurance of received product (condensate) with meter proving capabilities.
Rally developed scope of work through all project life cycle phases (conceptual/study phase, Front End Engineering and Design (FEED), execution of detailed engineering, and procurement and construction management support of the expanded facility).
Rally delivered all phases of engineering work, from initial concept development to front-end design, detailed engineering, procurement, and construction management. The work was divided into three main multi-discipline scopes to sharpen the focus on cost and schedule control.
#1: Ship 50 percent more diluted bitumen. Rally replaced the existing dilbit booster pumps with three new 1750 hp API 610 VS7 deep-can vertical pumps. The design scope included pump foundations, 4.16kV switchgear, piping, cabling, and electrical heat tracing.
#2: Installed two new 700 hp API 610 BB2 pumps to enable delivery of high-pressure dilbit. The scope included custody transfer metering and provisions for portable meter proving.
#3: Modified the existing terminal to facilitate custody transfer metering and meter proving capabilities for incoming condensate. Rally also designed an innovative underground road crossing which connected electrical equipment on either side of an existing roadway.
