The UK company provided the unique 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 originally used titanium alloy for all wetted components.
During a routine capital assessment, ADNOC determined the pumps had been due for refurbishment. The sodium hypochlorite dosing pumps are important to manufacturing and refurbishment had to align precisely with a specific 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 capable of complete the strip and assessment report inside 5 working days and suggest two refurbishment tasks. The first concerned a full rebuild, check and warranty of the first pump replacing all of the titanium components together with impeller, shaft, bearing brackets and mechanical seals. เครื่องมือใช้วัดความดัน needed to be completed in just eight weeks. Amarinth prioritised the ordering of the titanium elements and was capable of have the elements manufactured and shipped to the UAE to align with the rebuild schedule. The second venture undertook the identical work on the opposite two backup pumps to be completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, mentioned: “Having equipped the unique pumps to ADNOC we now have a wealth of expertise in working with titanium parts. We are also happy with the growth of our local UAE facility for service and support and which enabled us to successfully expediate this explicit refurbishment, benefiting each ADNOC and the local financial system.”
