Instumentation • Computing • Control
Fiscal flow measurement is a critical part of custody transfer and any small deviation in measurement accuracy of the meter can have a major impact on profitability. Interfacing and configuring the flow meters with the flow computer requires a thorough knowledge of the metering process. Rising to this challenge, Orbital has installed and configured over 150 flow computers in the UK alone. In most custody transfer installations the company supplies a complete turnkey package which would include upstream and downstream spools, pressure and temperature measurement, fiscal meters, the flow computer, the gas quality analyser and a sampling system. Orbital has installed numerous complete metering packages at various locations around the UK. Te majority of systems installed have been supplied as complete skids with inlet stream isolation and headers, meter tubes complete with secondary instrumentation, pay and check configuration, start-up stream with switch over technology for power stations but where required, it has also supplied standalone meters with the upstream and downstream pipe being supplied by the client. In the past few years the company installed systems and skids for, amongst others, National Grid, Wales and West, Centrica, Centrax, Uskmouth and Dragon LNG. At Dragon LNG Milford Haven Orbital worked in conjunction with AMEC to design, manufacture, install and commission two six inch and eight inch USM metering skids. Te company also works in partnership with SICK for the supply of ultrasonic meters.
Te company is currently working on a major project in conjunction with GL Industrial Services
to replace existing orifice plate gas metering systems. Te project involves the supply, installation and commissioning of orifice plates, pressure transmitters, flow computers and other associated components at 23 National Grid sites across the UK.
Bespoke metering systems For its part, the IMS Group is a supplier of bespoke metering systems tailored to the precise requirements of its customers. Te company’s skid- mounted solutions incorporate all major primary flow elements including ultrasonic, turbine, orifice, and positive displacement meters to meet client’s preference, but also ensuring the most economical solution. As an independent systems integrator the IMS Group is able to provide the optimal solution, selecting from all available products. Pre-fabricated skid-mounted solutions allow better quality control and minimise site installation costs. With multiple systems installed around the world, the company says its metering systems are synonymous with high quality and innovation.
When dealing with liquid and gas hydrocarbon extraction it is important to assess the composition of the extracted hydrocarbons. Traditional methods separate liquids and gas phases prior to analysis and metering, but these solutions can be cumbersome and economically unviable. Te IMS Group provides complete multi-phase metering solutions that can register individual flow rates of oil, gas and water coming from a wellhead. A multiphase meter provides accurate readings and provides the advantage of continuous well monitoring. Additionally, multiphase meters weigh less and require less space than traditional technology solutions and therefore are more economically advantageous.
FMC wins Fram H-Nord contract F
MC Technologies has signed an agreement with Statoil for the
manufacture and supply of subsea production equipment to support the Fram H-Nord development. Te contract has a value of approximately US$70m (€56m) to FMC. FMC’s scope of supply includes one
subsea production tree, one manifold and one multiphase meter. Te company will also supply an integrated template structure, one umbilical, two wellheads and additional controls and equipment. Te Fram H-Nord field is located in the Norwegian sector

of the North Sea in water depths of approximately 360 metres. Te equipment will be based on the standard fast-track subsea solution designed by FMC for Statoil. Deliveries are expected to occur throughout 2013. “Fram H-Nord is the sixth fast-
track project that we have been awarded from Statoil in the past two years,” said Tore Halvorsen, FMC’s senior vice president, subsea technologies. “We are pleased that Statoil continues to rely upon our experience and systems to support
these projects and to increase oil recovery.”
EMAS AMC has also won a contract from Statoil to deliver subsea, umbilical, risers and flowlines for marine installation and pipe lay at Fram H-Nord. Worth US$55m (€44m), this is the third phase of the development of the Fram Field which is tied back to the Troll C Platform. Fram H-Nord will be developed with one satellite well tied back to the existing infrastructure at Fram Vest A2 template via twin flowlines and a control and service umbilical. ●
