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 situated within the Arabian Gulf, 30km north-west of Abu Dhabi, UAE. Because sodium hypochlorite is highly corrosive, Amarinth initially 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 critical to manufacturing and refurbishment had to align exactly with a specific shutdown schedule.
The shutdown schedule would not enable 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 place to complete the strip and evaluation report inside 5 working days and suggest two refurbishment projects. The first concerned a full rebuild, check and guarantee of the first pump changing 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 components and was capable of have the components manufactured and shipped to the UAE to align with the rebuild schedule. The second project undertook the same work on the opposite two backup pumps to be accomplished on a 24-week schedule.
Deadline , managing director of Amarinth, said: “Having provided the unique pumps to ADNOC we have a wealth of experience in working with titanium elements. We are also happy with the growth of our native UAE facility for service and assist and which enabled us to efficiently expediate this particular refurbishment, benefiting each ADNOC and the native economy.”
