Auk North is a 4 - 6 well step out development using downhole Electrical Submersible Pumps (ESPs) to connect the wellheads via subsea tie in spools to a production manifold and protection structure. The manifold includes a test header with multi-phase flowmeter, umbilical termination and control system. The export flowline from the manifold is a subsea tie back terminating at a new caisson riser at the bridge linked Fulmar Advance Drilling (AD) platform.
The new Fulmar 'AD' caisson riser contains an 8" production flowline, at a design pressure of 345bar and temperature of -100C to 900C, a 10" J-Tube with an electro-hydraulic control and chemical injection umbilical from the platform to the Auk North manifold, and a 12" J-Tube with the ESP cable similarly routed from Fulmar 'AD' to the Auk North manifold.
The production flowline is connected with tie-in spools, from the pipeline end flange to the Fulmar 'AD' riser tie-in flange.
