The UK company provided the original pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform located 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 evaluation, ADNOC decided the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are crucial to manufacturing and refurbishment had to align precisely with a selected 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 evaluation report within 5 working days and propose two refurbishment initiatives. The first involved a full rebuild, test and guarantee of the first pump replacing all the titanium parts including impeller, shaft, bearing brackets and mechanical seals. The work wanted to be accomplished in just eight weeks. digital pressure gauge prioritised the ordering of the titanium components and was capable of have the elements manufactured and shipped to the UAE to align with the rebuild schedule. The second challenge undertook the identical work on the other two backup pumps to be accomplished on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, mentioned: “Having equipped the unique pumps to ADNOC we now have a wealth of expertise in working with titanium elements. We are also pleased with the expansion of our local UAE facility for service and support and which enabled us to successfully expediate this explicit refurbishment, benefiting both ADNOC and the native financial system.”
