by taking advantage of an increased pipeline design pressure and lower oil viscosity in the summer months. Sulzer Pumps were able to retrofit the existing main oil line pumps to provide an additional 26,000 barrels per day. This was achieved with higher flow, high efficiency pump hydraulics avoiding the need to up-rate the drivers or auxiliary equipment. In order to prevent any disruption to pipeline operation, the up-rated pump hydraulics were supplied in kit form and installed on site avoiding transporting the pumps to a service center. The resulting substantial increase in oil production delivered project payback within a matter of days.
