The UK firm equipped the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform positioned 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 parts.
During a routine capital assessment, ADNOC decided the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are crucial to manufacturing and refurbishment needed to align exactly with a particular shutdown schedule.
The shutdown schedule would not allow 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.

The work needed to be accomplished in just eight weeks. Amarinth prioritised the ordering of the titanium components and was able to have the components manufactured and shipped to the UAE to align with the rebuild schedule. The second challenge undertook the same work on the other two backup pumps to be completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, mentioned: “Having supplied the original pumps to ADNOC we have a wealth of expertise in working with titanium parts. We are additionally pleased with the expansion of our native UAE facility for service and assist and which enabled us to efficiently expediate this particular refurbishment, benefiting both ADNOC and the native financial system.”
