CNOOC
CNOOC International is a leading upstream business in the UK North Sea and operator of the Buzzard, Golden Eagle and Scott assets. The latter is located approximately 185 kilometres north-east of Aberdeen and commenced production in 1993. The Scott installation comprises two independent bridge linked platforms each supported by steel jackets. The two platforms are the drilling and process platform (DP), and the utilities and quarters platform (UQ)
The Scott, Telford and Rochelle fields are tied into the platform. The Scott and Telford fields continue to produce through Scott. The Rochelle field reached COP in 2019. The CNOOC International strategy for Scott is to maximise recovery from the Scott and Telford fields in a safe and environmentally responsible manner, defer abandonment costs and attract third party or equity tieback developments. The new rigid Telford water injection pipeline will be trenched by ploughing with the top of the pipeline approx. 0.6m below the seabed. As part of the pipeline upgrade, CNOOC expressed a requirement for accurate and precise injection of scale inhibitor into the line. ABLE were contracted to supply a dosing skid with three stainless steel Rheonik RHM015 Coriolis Mass Flow Meters each with ½” process connections. The meters were designed for 221barg at 10 litres/hr with a minimal pressure drop of 0.1 bar. Accuracy was verified at 0.2% of rate.
