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

The UK company provided the original 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 very corrosive, Amarinth initially used titanium alloy for all wetted elements.
During a routine capital assessment, ADNOC determined the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are important to manufacturing and refurbishment needed to align precisely with a specific shutdown schedule.
The shutdown schedule wouldn’t 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 evaluation report within five working days and suggest two refurbishment tasks. The first concerned a full rebuild, test and guarantee of the first pump changing all of the titanium components including impeller, shaft, bearing brackets and mechanical seals. The work needed to be completed in simply eight weeks. Amarinth prioritised the ordering of the titanium elements and was capable of have the components manufactured and shipped to the UAE to align with the rebuild schedule. เกวัดแรงดัน undertook the same work on the opposite two backup pumps to be completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, mentioned: “Having supplied the original pumps to ADNOC we have a wealth of expertise in working with titanium parts. We are also pleased with the expansion of our local UAE facility for service and assist and which enabled us to successfully expediate this explicit refurbishment, benefiting each ADNOC and the local economy.”
