The UK firm equipped the unique 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 extremely corrosive, Amarinth originally 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 specific shutdown schedule.
The shutdown schedule wouldn’t 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 evaluation report inside five working days and suggest two refurbishment initiatives. The first concerned a full rebuild, take a look at and warranty of the primary pump replacing all of the titanium parts together with impeller, shaft, bearing brackets and mechanical seals. The work wanted to be accomplished in simply eight weeks. Amarinth prioritised the ordering of the titanium parts and was in a position 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 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’ve a wealth of experience in working with titanium parts. We are also pleased with the growth of our native UAE facility for service and help and which enabled us to successfully expediate this particular refurbishment, benefiting each ADNOC and the local financial system.”
