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 evaluation, ADNOC decided the pumps were due for refurbishment. The sodium hypochlorite dosing pumps are important to production and refurbishment had to align precisely with a particular shutdown schedule.
The shutdown schedule wouldn’t 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 within five working days and propose two refurbishment projects. The first concerned a full rebuild, check and warranty of the first pump replacing all of the titanium parts including impeller, shaft, bearing brackets and mechanical seals. The work wanted to be completed in just eight weeks. เกจวัดแรงดูด prioritised the ordering of the titanium elements and was in a position to have the parts manufactured and shipped to the UAE to align with the rebuild schedule. The second venture undertook the identical 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 components. We are also pleased with the expansion of our native UAE facility for service and help and which enabled us to efficiently expediate this specific refurbishment, benefiting each ADNOC and the native financial system.”
