The UK firm equipped the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform located 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 assessment, ADNOC decided the pumps were due for refurbishment. The sodium hypochlorite dosing pumps are important to production and refurbishment had to align exactly with a selected 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 capable of complete the strip and assessment report within five working days and suggest two refurbishment projects. The first involved a full rebuild, check and guarantee of the first pump changing all of the titanium parts together with impeller, shaft, bearing brackets and mechanical seals. The work needed to be completed in simply eight weeks. Amarinth prioritised the ordering of the titanium parts and was capable of have the parts 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, said: “Having supplied the original pumps to ADNOC we have a wealth of expertise in working with titanium elements. เพรสเชอร์เกจ are additionally happy with the expansion of our native UAE facility for service and support and which enabled us to successfully expediate this explicit refurbishment, benefiting each ADNOC and the native financial system.”
