PALL Corporation – Amarinth work with PALL Corporation and enable Shell to meet OSPAR regulations in the North Sea

High alloy, high performance

The project required four pumps that had to work in a hostile hydrogen sulphide environment and the specific performance requirements for the separator meant that an off-the-shelf solution was not feasible. The operator specified that the chosen manufacturer also had to be ISO 9001 compliant. Amarinth were chosen to supply the pumps as they ascertained that a technical compliant solution could be delivered within the lead time by utilising its proven ‘C’ series heavy duty ISO 5199 chemical pump as the core of a solution. Amarinth had already manufactured such pumps with super duplex, NACE compliant casing materials and so had proven that they could survive the corrosive environment in which they had to operate.

For the pumps’ sealant systems, Amarinth were able draw on the expertise of its own Protect System division that had been supplying Shell for many years. Using the Protect System ATEX compliant System 1000 sealant system meant that the majority of major components were able to manufactured in-house. This gave not only a price benefit, but importantly more control over the manufacturing program, something that was critical to achieving the lead time. Finally the hydraulic performance of the pumps was modified to ensure that the separator could achieve maximum efficiency.

On-time contaminant reductions

The package was delivered on-time ensuring that Shell were able to meet the strict deadlines set by OSPAR and thereby avoid the hefty penalties of non-compliance. During the project close out meeting, Shell commented that the package was exceeding expectations and was consistently able to achieve the targets set. Amarinth has since been engaged on other demanding OSPAR projects helping North Sea operators such as Maersk, ConocoPhillips and Amereda Hess comply with the OSPAR regulations, thereby improving water quality in the North Sea.
