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

เกจ์วัดแรงดัน equipped the original 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 very corrosive, Amarinth initially used titanium alloy for all wetted components.
During a routine capital assessment, ADNOC determined the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are important to production and refurbishment needed to align precisely with a specific shutdown schedule.
The shutdown schedule would not enable 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 in a position to full the strip and assessment report inside 5 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 of the titanium parts including impeller, shaft, bearing brackets and mechanical seals. The work needed to be accomplished in just eight weeks. Amarinth prioritised the ordering of the titanium elements and was able to have the elements manufactured and shipped to the UAE to align with the rebuild schedule. The second challenge undertook the same work on the other two backup pumps to be accomplished on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, stated: “Having equipped the original pumps to ADNOC we now have a wealth of experience in working with titanium components. We are also happy with the expansion of our local UAE facility for service and support and which enabled us to successfully expediate this particular refurbishment, benefiting each ADNOC and the native economy.”
