The use of intelligent services extended the life of Drau- gen and Ormen Lange safety and automation systems by an additional 20 years by developing an upgrade or replace- ment path for each item of hardware and software. The plan minimizes risk and expenditure while safeguarding Shell's existing high availability. Furthermore, thousands of hours of work are performed annually by authorized ABB personnel from remote mon- itoring and operations rooms at ABB locations in Norway. This remote access enables ABB to safely implement changes, troubleshoot, provide support and carry out health checks, reducing the burden on Shell. A range of intelligent applications continually analyze data to find new ways to increase productivity. For instance, an automatic choke control application has reduced the startup time of Ormen Lange's 16 low-pressure wells from 9 hours to 2 hours. High-pressure wells have seen startup times fall by 18 hours. Previously, the wells had been started using slow preset speeds to prevent gravel and sand incursion from de- stroying the wells. Now critical well variables are managed in real time, matching ramp-up speed adjustments to actual process dynamics. Another example is how dynamic speed control of the on- shore pumps responsible for pushing monoethylene glycol through the pipelines to the well has cut costs for Shell by en- abling it retire one of its regeneration trains and decrease overall energy consumption. Shell also is able to ship more gas since less space is taken up by the monoethylene glycol in the pipelines. In terms of intelligent engineering and intelligent infrastruc- ture, ABB has integrated Shell's process control and process safety systems into a "single yet separate" entity, which would more traditionally have been supplied by two different vendors. Any change has to be approved, first by the ABB technical account manager and then by Shell. The outcome has been an exceptional safety record and a vast bank of information that can then be analyzed to improve further. Transitioning to a more digitalized OGC environment is exciting but not easy. Winners will use the current downturn to reimagine their entire business model and take a long-term, holistic view that deploys digitalization, not in a few isolated pockets but across their whole operation as discussed in the above case studies. n Dan Overly is the global head of products, oil, gas and chemicals for ABB. The ENI Norge's Goliat FPSO is the oil and gas industry's first project in the Barents Sea located within the Arctic Circle.
