Alderley Application Notes Crude Oil Metering Project Name: Dunlin Alpha Export Oil Metering Upgrade Location: Dunlin Alpha, northern North Sea, approx. 195km north east of Shetland EPC Contractor/Consultants: Amec End User: Fairfield Energy (UK) Ltd. Scope of Application The scope of supply includes a replacement crude oil metering package consisting of 3 x 50% metering streams and master metering stream. Each stream is constructed from 4” LTCS 600# RF pipework and includes manual and Rotork actuated Oliver Twinsafe valves, ZaVeRo ball valves, MTM globe valves, a 3” 900# RF Emerson MicroMotion type CMF300M coriolis meter, Emerson pressure and temperature transmitters and a Leeds butterfly flow-balancing valve. The package is not skid mounted due to very limited offshore access, instead the equipment is suspended from the overhead steels above a raised mezzanine area. The package also includes a 1600 x 600 x 2000mm control system with 4 x Emerson Floboss S600+ flow computers. Dunlin Alpha Technical excellence: delivered During commissioning Before upgrade
