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 fulfill strict shutdown deadlines.

The UK firm 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 very corrosive, Amarinth originally used titanium alloy for all wetted elements.
During a routine capital assessment, ADNOC determined the pumps have been due for refurbishment. Shh! dosing pumps are crucial to production and refurbishment had to align exactly with a specific shutdown schedule.
The shutdown schedule wouldn’t 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 in a place to complete the strip and assessment report within five working days and propose two refurbishment tasks. The first concerned a full rebuild, check and guarantee of the primary pump changing all the titanium components together with impeller, shaft, bearing brackets and mechanical seals. The work needed to be accomplished in just eight weeks. Amarinth prioritised the ordering of the titanium components and was in a place to have the components manufactured and shipped to the UAE to align with the rebuild schedule. The second venture 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 provided the unique pumps to ADNOC we’ve a wealth of experience in working with titanium elements. We are also pleased with the expansion of our local UAE facility for service and help and which enabled us to successfully expediate this explicit refurbishment, benefiting each ADNOC and the local economic system.”
