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 company equipped the original 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 very corrosive, Amarinth initially used titanium alloy for all wetted components.
During pressure gauge octa , ADNOC decided the pumps had been due for refurbishment. The sodium hypochlorite dosing pumps are important to manufacturing and refurbishment needed to align exactly with a particular 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 place to complete the strip and assessment report inside five working days and suggest 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 completed in just eight weeks. Amarinth prioritised the ordering of the titanium parts and was in a position to have the components 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, stated: “Having supplied the unique pumps to ADNOC we now have a wealth of expertise in working with titanium components. We are also happy with the expansion of our native UAE facility for service and help and which enabled us to efficiently expediate this particular refurbishment, benefiting each ADNOC and the native economy.”
