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

The UK firm supplied 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 highly corrosive, Amarinth originally used titanium alloy for all wetted elements.
During a routine capital assessment, ADNOC decided the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are important to production and refurbishment had to align exactly with a particular shutdown schedule.
The shutdown schedule would not allow 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 capable of complete the strip and assessment report inside five working days and propose two refurbishment projects. The first concerned a full rebuild, take a look at and warranty of the first pump changing all the titanium parts including impeller, shaft, bearing brackets and mechanical seals. The work needed to be accomplished in simply eight weeks. Amarinth prioritised the ordering of the titanium parts and was able to have the elements manufactured and shipped to the UAE to align with the rebuild schedule. เกจวัดแก๊ส 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 equipped the unique pumps to ADNOC we have a wealth of expertise in working with titanium components. We are also happy with the growth of our native UAE facility for service and assist and which enabled us to successfully expediate this explicit refurbishment, benefiting each ADNOC and the native financial system.”
