The UK company supplied the original 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 highly corrosive, Amarinth initially 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 exactly with a specific 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 capable of full the strip and evaluation report inside 5 working days and propose two refurbishment tasks. The first concerned a full rebuild, test and warranty of the primary pump replacing all of the titanium components together with impeller, shaft, bearing brackets and mechanical seals. The work wanted to be accomplished in just eight weeks. เพชเชอร์เกจ prioritised the ordering of the titanium parts and was in a position to have the components manufactured and shipped to the UAE to align with the rebuild schedule. The second project undertook the identical work on the opposite two backup pumps to be accomplished on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, said: “Having supplied the original pumps to ADNOC we’ve a wealth of experience in working with titanium parts. We are also happy with the growth of our native UAE facility for service and support and which enabled us to successfully expediate this explicit refurbishment, benefiting both ADNOC and the local financial system.”
