The UK firm provided the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform positioned in 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 decided the pumps were due for refurbishment. The sodium hypochlorite dosing pumps are important to production and refurbishment needed to align exactly with a specific shutdown schedule.
เกจวัดแรงดันแก๊สlpg would not allow 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 evaluation report inside five working days and propose two refurbishment tasks. The first concerned a full rebuild, test and guarantee of the first pump replacing all the titanium components 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 parts and was able to have the parts 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, said: “Having supplied the unique pumps to ADNOC we now have a wealth of experience in working with titanium elements. We are additionally happy with the expansion of our local UAE facility for service and support and which enabled us to successfully expediate this specific refurbishment, benefiting both ADNOC and the native economic system.”
