Amarinth refurbishes titanium pumps for ADNOC

Amarinth has refurbished sodium hypochlorite dosing pumps for ADNOC on schedule using its facility within the United Arab Emirates to meet strict shutdown deadlines.

The UK company provided the unique pumps to ADNOC in 2016 for sodium hypochlorite dosing duties on the Umm Lulu offshore platform positioned within 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 determined the pumps were due for refurbishment. The sodium hypochlorite dosing pumps are important to manufacturing and refurbishment had to align precisely 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 complete the strip and evaluation report within 5 working days and suggest two refurbishment initiatives. The first concerned a full rebuild, check and warranty of the primary pump changing all the titanium elements together with impeller, shaft, bearing brackets and mechanical seals. The work wanted to be accomplished in simply eight weeks. Amarinth prioritised the ordering of the titanium elements and was able to have the components manufactured and shipped to the UAE to align with the rebuild schedule. The second venture undertook the identical work on the other two backup pumps to be accomplished on a 24-week schedule.
เกรดวัดแรงดัน , managing director of Amarinth, stated: “Having provided the unique pumps to ADNOC we’ve a wealth of experience in working with titanium parts. We are also happy with the expansion of our local UAE facility for service and help and which enabled us to efficiently expediate this particular refurbishment, benefiting each ADNOC and the native economy.”
