The UK firm provided the original pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform positioned in the Arabian Gulf, 30km north-west of Abu Dhabi, UAE. Because sodium hypochlorite is highly corrosive, Amarinth originally used titanium alloy for all wetted elements.
During a routine capital assessment, ADNOC determined the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are critical 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.
Amarinth’s UAE facility was able to complete the strip and evaluation report inside 5 working days and suggest two refurbishment projects. The first concerned a full rebuild, check and warranty of the first pump replacing all of the titanium parts together with impeller, shaft, bearing brackets and mechanical seals. The work wanted to be completed in simply eight weeks. Amarinth prioritised the ordering of the titanium parts and was capable of have the parts 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 accomplished on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, mentioned: “Having provided the unique pumps to ADNOC we’ve 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 economic system.”
