Amarinth has refurbished sodium hypochlorite dosing pumps for ADNOC on schedule using its facility within the United Arab Emirates to meet strict shutdown deadlines.

The UK firm equipped the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform situated 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 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 needed to align precisely with a selected shutdown schedule.
The shutdown schedule wouldn’t permit 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 able to complete the strip and evaluation report inside five working days and suggest two refurbishment projects. The first concerned a full rebuild, check and warranty of the primary pump replacing all the titanium elements including impeller, shaft, bearing brackets and mechanical seals. เกจวัดแรงกด needed to be accomplished in simply eight weeks. Amarinth prioritised the ordering of the titanium parts and was able to have the parts manufactured and shipped to the UAE to align with the rebuild schedule. The second venture undertook the same work on the other two backup pumps to be completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, mentioned: “Having provided the original pumps to ADNOC we’ve a wealth of expertise in working with titanium components. We are also pleased with the growth of our native UAE facility for service and help and which enabled us to successfully expediate this explicit refurbishment, benefiting both ADNOC and the local financial system.”
