The UK company supplied the original pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform located 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 had been due for refurbishment. The sodium hypochlorite dosing pumps are important to production and refurbishment had to align exactly with a specific shutdown schedule.
The shutdown schedule wouldn’t permit 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 able to complete the strip and assessment report within five working days and suggest two refurbishment projects. The first involved a full rebuild, test and guarantee of the first pump changing all the titanium parts including impeller, shaft, bearing brackets and mechanical seals. เกจวัดอาร์กอน needed to be accomplished in just eight weeks. Amarinth prioritised the ordering of the titanium components and was capable of have the parts 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 original pumps to ADNOC we’ve a wealth of expertise in working with titanium elements. We are additionally pleased with the expansion of our native UAE facility for service and assist and which enabled us to successfully expediate this specific refurbishment, benefiting each ADNOC and the local financial system.”
