Two offshore operators have chosen SPX Flow Inc’s Plenty brand filters for their new floating production storage and offloading vessels (FPSOs).
The first project involved two backflush seawater filters and two sets of heating, cooling, fuel gas and diesel fine cartridge filters for a new FPSO being built to boost production capacity in the North Sea.
The fully customised units use a mix of materials from carbon steel and 316L SS to exotic super duplex stainless steel materials to meet harsh environmental conditions and are supplied with full QA and offshore documentation.
The automated backflush seawater intake filters remove debris down to 570 microns nominally including sand, shells and other particles, from the uplift pumps. Constructed of super duplex stainless steel, the filters are designed for continuous water flow without manual intervention through a reliable, positive and efficient cleaning action using an automatic cleaning cycle that is triggered based on either pressure drop across the unit, timer or manual intervention.
The second project, for an FPSO destined for South American waters, comprised three 14” cartridge filters for the SRP (sulphate recovery package) systems, designed to remove debris down to ten microns. Working with a UK upstream water solutions specialist to provide the complete filtration package, the cartridge filters were supplied with GD closures in a horizontal orientation. Shipped at the end of 2018, the units were again manufactured from super duplex stainless steel and supplied with full documentation and QA packages to meet operator and regulatory requirements.
