Amarinth has refurbished sodium hypochlorite dosing pumps for ADNOC on schedule using 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 situated 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 xp2i , ADNOC determined the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are important to production and refurbishment had to align exactly with a selected shutdown schedule.
The shutdown schedule would not 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 able to full the strip and assessment report inside 5 working days and propose two refurbishment tasks. The first involved 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 simply 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 identical work on the opposite two backup pumps to be completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, stated: “Having supplied the unique pumps to ADNOC we have a wealth of expertise in working with titanium components. We are additionally happy with the expansion of our local UAE facility for service and support and which enabled us to efficiently expediate this explicit refurbishment, benefiting each ADNOC and the local economic system.”
