Amarinth has refurbished sodium hypochlorite dosing pumps for ADNOC on schedule utilizing its facility within the United Arab Emirates to satisfy strict shutdown deadlines.

The UK firm provided the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform located within the Arabian Gulf, 30km north-west of Abu Dhabi, UAE. Because sodium hypochlorite is highly corrosive, Amarinth originally used titanium alloy for all wetted components.
During a routine capital assessment, ADNOC decided the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are important to production and refurbishment needed to align precisely with a particular shutdown schedule.
เครื่องมือตรวจวัดความดันเลือดเรียกว่า would not allow the pumps to be returned to the UK for a full strip, assessment and refurbishment, so Amarinth used its UAE facility to undertake the work.
Amarinth’s UAE facility was capable of complete the strip and assessment report within 5 working days and suggest two refurbishment projects. The first concerned a full rebuild, test and guarantee of the primary pump replacing all of the titanium parts including impeller, shaft, bearing brackets and mechanical seals. The work wanted to be completed in just eight weeks. Amarinth prioritised the ordering of the titanium elements and was able to have the components manufactured and shipped to the UAE to align with the rebuild schedule. The second venture undertook the same work on the opposite two backup pumps to be accomplished on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, stated: “Having supplied the original pumps to ADNOC we now have a wealth of expertise in working with titanium elements. We are also pleased with the growth of our native UAE facility for service and support and which enabled us to successfully expediate this specific refurbishment, benefiting both ADNOC and the native financial system.”
