... and reliability and enhance oil recovery rates. This paper analyses the opportunities that can be exploited with the implementation of technology insertion and discusses some options available to operators. Each of these older fields has developed its own characteristics since its original deployment and thus...

... efficiency and availability. Control systems are a key element in addressing this challenge. The next generation of control systems must provide superior availability, lower lifecycle costs and superior performance. Other industries faced with similar increases in complexity and the demand for very high...

... was ensured on system availability. The approach chosen had two separate systems: channel A and channel B, with end-to-end redundancy constantly from surface-to-subsea actuators and sensors. Sensors on the subsea trees are redundant and fully isolated from each other. Taking into consideration the amount...

.... A significant benefit of the dry-wet solution is the availability of DC power distribution to the wet nodes (circa 10 kW/node). When combined with all electric subsea systems, this offers the opportunity for cost-effective high-reliability control systems in any offshore area. This paper will introduce a number...

... specification means that vendors are often constrained into tendering their cheapest solution, in order to maintain competitiveness The cheapest solution may appear to be 'fit for purpose', but for how long? It is not sufficient merely to specify the reliability or availability of a system, there are differing...
