The UK firm provided the original 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 very corrosive, Amarinth originally used titanium alloy for all wetted parts.
During a routine capital assessment, ADNOC decided the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are critical to production and refurbishment had to align precisely with a specific 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 capable of complete the strip and evaluation report inside five working days and propose two refurbishment initiatives. The first involved a full rebuild, take a look at and warranty of the first pump replacing all the titanium parts together with impeller, shaft, bearing brackets and mechanical seals. The work wanted to be completed in simply eight weeks. Amarinth prioritised the ordering of the titanium parts and was in a position to have the elements manufactured and shipped to the UAE to align with the rebuild schedule. The second project undertook the identical work on the other two backup pumps to be completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, said: “Having provided the original pumps to ADNOC we now have a wealth of experience in working with titanium parts. We are additionally happy with the expansion of our local UAE facility for service and assist and which enabled us to successfully expediate this explicit refurbishment, benefiting both ADNOC and the local financial system.”
