Emerson Process Management has won a multi-million dollar contact to deliver its Roxar subsea instrumentation to Lundin Petroleum’s Brynhild field in the North Sea.
The contract was awarded by Aker Solutions, one of the world’s leading providers of oilfield products, systems and services, and covers Roxar subsea multiphase meters, subsea Sencorr pressure and temperature sensors, subsea chemical injection valves, and sand monitors. Aker Solutions will use the instrumentation as part of the rolling out of a complete subsea production system on Brynhild, with Emerson also delivering a number of downhole pressure and temperature gauges directly to Lundin Petroleum.
“This is a landmark agreement for a number of reasons,” said Svenn Haugen, World Area Director Europe & North Africa, Roxar Flow Measurement. “Firstly, our instrumentation is to be deployed on a tie-back where key input measurements for fiscal allocation and production measurement will be carried out subsea, requiring the very best in accurate and robust subsea solutions. Secondly, it is a solution package covering both multiphase flow measurement and downhole monitoring, chemical injection and sand detection. We are delighted that Lundin and Aker Solutions put their trust in Emerson for such an important project.”
The tieback from Brynhild to the Pierce field’s FPSO (Floating, Production Storage & Offloading) platform in the UK sector is a cross-border subsea tie-back where key data for fiscal allocation and production measurement are gathered subsea. Combining the Brynhild and Pierce’s tie-back flow will avoid the need for a dedicated riser for Brynhild. The Roxar subsea instrumentation will be crucial to generating accurate measurement and input to fiscal allocation from the different flow streams.
Emerson’s solution for the Brynhild field will provide Lundin with high flow measurement accuracy, control and insight into their subsea operations.
* The Roxar subsea Multiphase meter provides accurate and continuous on-line monitoring of the flow rates of oil, water and gas in subsea well streams.
* The Roxar subsea SenCorr pressure and temperature (PT) sensors are built for long-life operations in harsh subsea production environments. A silicon piezoresistive sensor measures both pressure and temperature from the same measurement bridge, giving complete temperature compensation of the pressure reading.
* The Roxar subsea Chemical Injection valve (High Flow) is a reliable, compact and robust retrievable solution providing total control over the injection of inhibitors; and
* The Roxar Sand monitor is a nonintrusive acoustic sand monitoring system that enables operators to optimize production by enabling the determination of maximum sand-free rates or maximum acceptable sand production rates.
The Brynhild field is located northwest of the Ula field and 38 kilometers north-north-east of the Pierce field. The water depth is approximately 80 meters. In November 2011, Aker Solutions signed a US$122 million contract with Lundin Petroleum for the engineering, procurement and construction of a subsea production system for the Brynhild field.
