Swire Production Solutions has worked closely with Dynamic Process Systems (DPS) of Bristol in the UK to design a modular, robust, marine process system which can be fitted to either the Swire Modular FPSO or the Swire A&EDS.

The modularised process system has a three phase, three stage (three separator) separation and oil stabilisation system which can be fitted to any appropriate platform. The foot print is small enough to fit on a standard UT755L hull in the case of the A&EDS, whilst higher capacity gas compression, condensate processing and water injection facilities can be accommodated on a larger platform such as the Swire Modular FPSO.

Swire Production Solutions are able to further refine or customise the production system to meet a wide range of customer requirements. However, as currently configured the system has been designed to meet the following specifications:

Well fluids flow up from up to four wells, via separate risers. The wells may utilise dry trees on wellhead platforms or wet trees as defined by the field layout. Flexible hoses are used to transfer the fluids to the choke valves on the vessel, where a break in pressure rating occurs and the flow from the wells is regulated. The system can be configured as three stage using multiphase meters for well test or as two stage, where the first two separators would be used singly allowing one well to be diverted to one separator. A separate choke manifold is also supplied to allow gas separated in the process plant which has been compressed to be returned to the well and be used for gas lift.

On the A&EDS vessel the process package is positioned directly on the ship deck at the stern between frame 2 & 35 (a raised deck is not required as there will be no storage on the vessel). The overall foot print of the package is 22.5m by 13m and may be supplied on more than one deck level. Well fluids enter the process at the forward end and exit for export at the aft end.

On the Swire Modular FPSO the process system is sited, according to class rules, on a
mezzanine deck approximately 3m above the main deck, so that the hazardous areas
do not conflict with other operations.

DPS have designed the process system to be modular so that additional gas handling equipment, with capacity up to 100mmscf/day, condensate processing spread up to 10,000 barrels per day or water injection equipment can be integrated if required.
