50% time reduction for an average maintenance session
80% reduction in hours engineers spend on testing
66% reduction in annual maintenance checks
Aker BP used DataOps provided by Cognite, including Cognite Data Fusion (CDF), to optimize the process shutdown (PSD) valve maintenance process, creating a system that automatically logs when the valves were last operated and whether they fulfilled travel time demands.
Aker BP used Cognite Data Fusion to automate and optimize the PSD valve maintenance process at the Valhall field and make data available to engineers in the Asset Data Insight application, which can be accessed on computers, smartphones, and tablets.
Cognite Data Fusion ingests data from Aker BP’s control system, logging when valves are used and comparing the results to travel time criteria. Engineers can then see an overview of all the valves in Asset Data Insight and generate work orders for valves that don’t meet the set criteria.
The valves can also be displayed in a 3D model of the platform, giving engineers a visual tool for quickly locating different pieces of equipment on the installation.
In the future, Aker BP plans to integrate its computerized maintenance management system (CMMS) with Cognite Data Fusion, which will enable the company to automatically generate work orders, further reducing the time spent on the administrative side of maintenance.
The shift toward more automation in maintenance means that engineers no longer have to grapple with a slow offshore system to check each valve manually. The change is estimated to reduce the number of hours that engineers spend on testing PSD valves a year by about 80 percent. It will also cut the number of annual maintenance checks by two-thirds, and the duration of an average maintenance session in half.
By reducing the time it takes to check safety-critical equipment, Aker BP can reinvest those resources toward maintaining production-critical equipment and performing other important tasks.
