Nama represents Amarinth as its agent for the emirate of Abu Dhabi and had identified an opportunity for Amarinth's expertise in pump supply on the Habshan Gas Complex Expansion project which will see the gas processing and re-injection capability doubled.
Part of this project called for horizontal API 610 OH2 pumps to be installed in an additional process train to existing gas fields. The pumps had to operate in a harsh environment to a specific and demanding hydraulic performance and so had to be manufactured from special exotic alloys which are rare, difficult to procure and challenging to machine. Despite this, the client needed these pumps delivering on a very tight deadline - just 40 weeks from order.
Bespoke versions of designs
A standard pump was not an option and although a number of manufacturers looked at the requirements none could meet both the technical requirements and the lead time demanded by the specifications provided by the client. Nama were quick to realise that the requirements ideally suited the capabilities of Amarinth.
The resulting solution complied fully with both the specifications and the lead time by creating a bespoke version of its proven API 610 OH2 horizontal pump in Alloy 825. The addition of API 682 Plan 53 accumulator systems and high temperature aluminium paint finish completed the solution. Following a comprehensive review of Amarinth by the client, it was awarded this prestigious contract.
Exotic alloy is notoriously hard to procure and difficult to cast. Despite all of this, Amarinth were able to supply fully specification compliant OH2 pumps well within deadline to fit with the clients project programme. An added complication also arose after order placement when a client process change meant that a particular pump duty was considerably altered. Amarinth's flexibility enabled it to accommodate this change within its supply with minimal cost impact and overall delivery implication, once again securing the project programme. All the units were subject to NDE and NDT including radiography, dye-penetrant of castings and welds, PMI and type 3.1 and 3.2 material certification of critical components. After assembly, extended API 610 tests were conducted in-house, witnessed by the client’s inspection agency. The high level of NDT meant that a large amount of documentation was required for the pump dossiers. Amarinth more than lived up to the client’s expectations by ensuring that the management of the contract and of the documentation deliverables were both at the same on-schedule pace at all times.
Amarinth, in conjunction with Nama (who will be undertake first level support), will be providing additional post order services to the client including pump commissioning and site assistance - an order for spare parts has already been received.
