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 company equipped the unique 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 highly corrosive, Amarinth initially used titanium alloy for all wetted elements.
During a routine capital evaluation, ADNOC determined the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are important to manufacturing and refurbishment had to align precisely with a particular 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 able to complete the strip and evaluation report inside five working days and suggest two refurbishment projects. The first concerned a full rebuild, test and guarantee of the primary pump changing all of the titanium components including impeller, shaft, bearing brackets and mechanical seals. pressure gauge 4 นิ้ว needed to be accomplished in just eight weeks. Amarinth prioritised the ordering of the titanium elements and was in a position to have the parts 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 completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, stated: “Having provided the unique pumps to ADNOC we now have a wealth of expertise in working with titanium elements. We are also happy with the growth of our local UAE facility for service and support and which enabled us to successfully expediate this particular refurbishment, benefiting both ADNOC and the local economic system.”
