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

The UK company equipped the unique 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 very corrosive, Amarinth initially used titanium alloy for all wetted parts.
During a routine capital evaluation, ADNOC decided the pumps were due for refurbishment. The sodium hypochlorite dosing pumps are critical to production and refurbishment had to align exactly with a particular shutdown schedule.
The shutdown schedule would not 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 5 working days and suggest two refurbishment projects. The first concerned a full rebuild, take a look at and warranty of the primary pump replacing all the titanium parts including impeller, shaft, bearing brackets and mechanical seals. The work wanted to be accomplished in just eight weeks. Amarinth prioritised the ordering of the titanium elements and was able 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 opposite 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 have a wealth of experience in working with titanium elements. We are additionally pleased with the expansion of our local UAE facility for service and assist and which enabled us to efficiently expediate this explicit refurbishment, benefiting each ADNOC and the local economy.”
