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 firm provided 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 extremely corrosive, Amarinth initially used titanium alloy for all wetted elements.
During a routine capital evaluation, ADNOC decided the pumps had been due for refurbishment. The sodium hypochlorite dosing pumps are critical to production and refurbishment needed 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, assessment 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 five working days and suggest two refurbishment tasks. The first involved a full rebuild, check and guarantee of the first pump changing all the titanium elements together with impeller, shaft, bearing brackets and mechanical seals. The work wanted to be completed in just eight weeks. Amarinth prioritised the ordering of the titanium components and was capable of have the parts manufactured and shipped to the UAE to align with the rebuild schedule. The second project undertook the same work on the other 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 have a wealth of experience in working with titanium parts. We are also happy with the expansion of our native UAE facility for service and support and which enabled us to successfully expediate this explicit refurbishment, benefiting both ADNOC and the local economy.”
