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

The UK company supplied the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform positioned in 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 determined the pumps were due for refurbishment. The sodium hypochlorite dosing pumps are crucial to manufacturing and refurbishment had 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 capable of full the strip and evaluation report inside 5 working days and suggest two refurbishment initiatives. The first concerned a full rebuild, test and guarantee of the primary pump replacing all the titanium elements including impeller, shaft, bearing brackets and mechanical seals. The work needed to be accomplished in simply eight weeks. Amarinth prioritised the ordering of the titanium parts and was able to have the components manufactured and shipped to the UAE to align with the rebuild schedule. The second venture undertook the identical work on the opposite two backup pumps to be accomplished on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, said: “Having equipped the original pumps to ADNOC we now have a wealth of experience in working with titanium parts. pressure gauge 10 bar are also happy with the expansion of our local UAE facility for service and support and which enabled us to efficiently expediate this particular refurbishment, benefiting each ADNOC and the native economic system.”
