ABB to deliver fastest upstream start-up for Aasta Hansteen’s first gas production

ABB is set to deliver what it believes to be the world’s fastest start-up when Equinor’s Aasta Hansteen gas field begins operating and produces its first gas later this year.

ABB is in the final phase of providing a suite of innovative ABB Ability digital technologies for Aasta Hansteen, which is located in 1300 meters of water in the Vøring area of the Norwegian Sea, 300 kilometers from land.

Part of the challenge for ABB was to make the first gas start-up process as quick and efficient as possible. For this, ABB needed to reduce a sequence of over 1000 manual interventions to as few as possible. The outcome is a series of buttons that are as simple as starting a car.

“Our teams went through the start-up steps, identified and defined obstacles that needed to be improved, then used our ABB Ability System 800xA simulator to do a virtual start-up of the plant,” said Per Erik Holsten, managing director for ABB Oil, Gas and Chemicals. “At this stage we made a lot of improvements for starting up and operating the plant. Through automating much of the process we managed to reduce a complex set of manual interventions to just 20, which means we are all set to deliver what we believe to be the world’s fastest start-up at first gas.”

The company estimates it saved about 40 days in the commissioning phase of the project, or nearly 2,700 man-hours by using the ABB Ability System 800xA simulator to identify and improve 57 areas in the start-up.

The ABB Ability System 800xA simulator is a solution that minimises risk and reduces the occurrence of unplanned shutdowns, while improving safety, productivity and energy savings. It has a control system that is disconnected from the physical process and is instead simulated by a dynamic process model. By seamlessly extending the Distributed Control System (DCS), the ABB Ability System 800xA provides the same look and feel as the core functional areas. It is a scalable solution in system size, functionality and control system connectivity and is available in three editions: Basic, Premium and Professional.

“In the operation of oil and gas projects there are lots of different automation and instrument competencies and disciplines required for the project to run smoothly,” Holsten said. “In upstream greenfield sites such as Aasta Hansteen, ABB is one of the few companies that is sufficiently skilled and resourced to connect the different parts of the jigsaw together to provide a truly connected plant. Aasta Hansteen is a great example of how it is possible to do just that, while making the start-up and operation of the plant more efficient.”

The ABB Ability System 800xA solution is part of a much bigger suite of digital technologies being implemented by ABB at Aasta Hansteen. These include a condition monitoring system to monitor more than 100,000 maintenance conditions from more than 4,000 pieces of equipment, tools for alarm management and alarm rationalisation, delivery of several safety critical applications, data storage solution to store all alarms and events easily, and third-party system integration of essential data traffic.
