The UK company equipped 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 very corrosive, Amarinth initially used titanium alloy for all wetted elements.
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 needed to align exactly with a particular 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 able to complete the strip and assessment report within 5 working days and suggest two refurbishment initiatives. The first concerned a full rebuild, test and guarantee of the first pump changing all the titanium parts including impeller, shaft, bearing brackets and mechanical seals. The work wanted to be accomplished in simply eight weeks. Amarinth prioritised the ordering of the titanium elements and was capable of have the elements manufactured and shipped to the UAE to align with the rebuild schedule. The second project undertook the same work on the opposite two backup pumps to be completed on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, stated: “Having equipped the original pumps to ADNOC we now have a wealth of expertise in working with titanium elements. We are additionally happy with the growth of our native UAE facility for service and help and which enabled us to successfully expediate this explicit refurbishment, benefiting both ADNOC and the native economic system.”
