Armada Hub Subsea Developments

Armada Map

Armada Hub installation consists of Drake, Hawkins and Fleming gas/condensate fields, with SW & NW Seymour and Maria fields in the UK Sector, Rev and Gaupe fields (3rd Party fields operated by Repsol Norge AS and AS Norske Shell) in the Norwegian Sector, all of which are tied back to Armada.

Entry Specification: Produced fluids must be commercially free of odours, materials, sand and solids/fluids that might interfere or cause injury to the proper operation of the Armada platform facilities; which for the avoidance of doubt shall include any material that would affect the merchantable value of Armada products.
Exit  Specification: To meet the required specifications of the Central Area Transmission System (CATS) for export gas and the Forties Pipeline System (FPS) for export condensate.
Outline details of Primary separation
processing  facilities:
"The Armada platform has a single gas processing train and a single condensate processing train for the Armada topsides well fluids and the Rev, Gaupe, Northwest Seymour and Maria subsea well fluids. Initial stage separation for the Armada topside well fluids is through a three-phase vertical separator. Initial stage separation for the Rev subsea well fluids is through a three-phase horizontal separator. Initial stage separation for the Gaupe, Northwest Seymour and Maria comingled subsea well fluids and Seymour Horst topsides well fluids is through a three-phase horizontal separator.
Outline details of gas treatment facilities: The Armada gas processing facilities comprise of a single gas compression train from the gas outlet of the three inlet separators. The gas compression train consists of booster compression followed by TEG dehydration and export compression.
