The UK company equipped 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 highly corrosive, Amarinth originally 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 precisely with a particular shutdown schedule.
The shutdown schedule 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 capable of full the strip and assessment report inside 5 working days and suggest two refurbishment initiatives. The first involved a full rebuild, take a look at and warranty of the primary pump changing all the titanium components including impeller, shaft, bearing brackets and mechanical seals. The work wanted to be completed in just eight weeks. เกจวัดแรงดันแก๊สอาร์กอน prioritised the ordering of the titanium elements and was in a place to have the elements manufactured and shipped to the UAE to align with the rebuild schedule. The second project undertook the same work on the other two backup pumps to be accomplished on a 24-week schedule.
Oliver Brigginshaw, managing director of Amarinth, mentioned: “Having supplied the original pumps to ADNOC we now have a wealth of expertise in working with titanium elements. We are also happy with the growth of our native UAE facility for service and support and which enabled us to successfully expediate this particular refurbishment, benefiting both ADNOC and the native economy.”
