The UK firm supplied the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform situated 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 elements.
During a routine capital evaluation, ADNOC determined the pumps have been due for refurbishment. The sodium hypochlorite dosing pumps are crucial to manufacturing and refurbishment needed to align precisely with a specific shutdown schedule.
The shutdown schedule wouldn’t allow 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 capable of full the strip and assessment report inside five working days and propose two refurbishment tasks. The first involved 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 simply eight weeks. Amarinth prioritised the ordering of the titanium parts 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 completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, stated: “Having supplied 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 support and which enabled us to efficiently expediate this explicit refurbishment, benefiting both ADNOC and the native economic system.”
