The UK firm supplied the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform located within the Arabian Gulf, 30km north-west of Abu Dhabi, UAE. Because sodium hypochlorite is extremely corrosive, Amarinth initially used titanium alloy for all wetted components.
During a routine capital evaluation, ADNOC determined the pumps had been due for refurbishment. The sodium hypochlorite dosing pumps are critical to manufacturing 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 assessment report inside 5 working days and propose two refurbishment initiatives. The first concerned a full rebuild, test and guarantee of the primary pump replacing all the titanium elements 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 components and was capable of have the components 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, said: “Having equipped the unique pumps to ADNOC we’ve a wealth of expertise in working with titanium parts. We are also happy with the growth of our local UAE facility for service and assist and which enabled us to efficiently expediate this explicit refurbishment, benefiting both ADNOC and the local financial system.”
