An innovative compact API 610 pumping solution from Amarinth gets Opus out of a tight squeeze

First Point Assessment

Space and weight are critical constraints in designing equipment for offshore applications and so a flexible approach was required on the project. Opus decided to look for a supplier registered with First Point Assessment (FPAL), the oil and gas supply chain database to identify potential suppliers. Amarinth was already FPAL registered and had previously provided bespoke pumps to Wood Group for the Amerada Hess Triton FPSO vessel for which Opus had also provided its CFU Technology. As such, Opus was confident that Amarinth would be able to provide a quality, on-time and cost effective solution. Initially Opus specified Amarinth’s API 610 OH2 A Series pump, but this was quickly ruled out as it was too big.

A truly bespoke solution

Amarinth suggested using their API 610 OH1 B Series pumps as these would be smaller. However, even these proved too big and so Amarinth set about designing a bespoke base plate to save even more space. Although a bespoke design, the new base plate actually contributed a cost saving to the project. During the project, Opus became aware that Amarinth could supply Protect System Plan 53A sealant systems. There were issues relating to where these could be placed in order that they did not hang over the side of the skid and there were also height considerations. Therefore a truly bespoke solution was designed by Amarinth comprising of a left and a right handed pump system that enabled everything to fit on the skid.

Commissioned on time

Without the innovative changes delivered by Amarinth, Opus would have had to undertake design alterations to the CFU, resulting in a more expensive solution and delaying the delivery of the package to the platform. Further CFU’s are expected to be installed on oil platforms in the North Sea and the compact design of the Amarinth B series solution will provide a competitive option where space is at a premium.
