The two pumps, originally supplied a decade ago, were key components in the hydrocarbon condensate process on Zirku Island, an ADNOC oil and gas processing hub.
As ADNOC sought to increase the plant's capacity, Amarinth engineers conducted an in-depth investigation and assessment of the existing pumps at Zirku Island. A comprehensive gap analysis was undertaken to determine how the horizontal pumps, originally designed and installed ten years ago, could be refurbished to comply with current ADNOC specifications and meet the increased capacity requirements. The goal was to deliver a solution with minimal impact on the plant’s operations.
The resulting approach included designing new pump casings, supplying a larger and more efficient motor, and upgrading to Variable Speed Drives (VSD). These enhancements allowed the pumps to achieve the higher capacity needed while maintaining the existing baseplate and skid arrangement, as the new motor fits seamlessly within the same footprint as the original. The Plan 53B seal support systems and mechanical seals were reused and recalibrated, avoiding the need for any modifications to the pipework or fittings, minimising downtime and costs for ADNOC.
Given ADNOC's requirement to keep the plant operational throughout the refurbishment process, Amarinth implemented a phased approach, refurbishing one pump at a time.
With over 450 Amarinth pumps already installed across ADNOC facilities, the collaboration further strengthens the long-standing relationship between the two companies.
