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 company supplied the original pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform positioned within the Arabian Gulf, 30km north-west of Abu Dhabi, UAE. Because sodium hypochlorite is very corrosive, Amarinth originally used titanium alloy for all wetted elements.
During a routine capital assessment, ADNOC decided the pumps had been due for refurbishment. The sodium hypochlorite dosing pumps are critical to manufacturing and refurbishment needed to align precisely with a selected shutdown schedule.
The shutdown schedule wouldn’t permit the pumps to be returned to the UK for a full strip, evaluation and refurbishment, so Amarinth used its UAE facility to undertake the work.
Amarinth’s UAE facility was in a position to complete the strip and assessment report within 5 working days and propose two refurbishment initiatives. The first concerned a full rebuild, test and guarantee of the primary pump replacing all of the titanium elements together with impeller, shaft, bearing brackets and mechanical seals. เกจวัดแรงดันแบบแห้ง wanted to be accomplished in just eight weeks. Amarinth prioritised the ordering of the titanium elements and was in a position to have the elements manufactured and shipped to the UAE to align with the rebuild schedule. The second challenge undertook the identical work on the opposite two backup pumps to be completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, mentioned: “Having equipped the original pumps to ADNOC we’ve a wealth of expertise in working with titanium components. We are also happy with the expansion of our native UAE facility for service and support and which enabled us to efficiently expediate this explicit refurbishment, benefiting each ADNOC and the local economic system.”
