The UK company 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 very 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 crucial to manufacturing and refurbishment needed to align precisely with a particular shutdown schedule.
The shutdown schedule would not enable 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 in a position to full the strip and assessment report inside 5 working days and propose two refurbishment initiatives. The first concerned a full rebuild, test and guarantee of the primary 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 components and was able 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 other two backup pumps to be accomplished on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, mentioned: “Having supplied the original pumps to ADNOC we’ve a wealth of experience in working with titanium parts. เครื่องมือความดัน are also pleased with the growth of our local UAE facility for service and support and which enabled us to efficiently expediate this particular refurbishment, benefiting each ADNOC and the native economic system.”
