How Cognite helped Aker BP save time and costs by automating maintenance

The E&P company slashed maintenance expenses and increased worker safety.

Cognite worked with Aker BP to liberate control system data, redirecting resources to production-critical equipment at the Valhall oil field.

In Short

Calendar-based maintenance is an inefficient method of checking the status of equipment, as engineers spend much of their time checking equipment in good working condition.

Aker BP used Cognite Data Fusion 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.

Challenge

PSD valve testing on the Valhall used to be time consuming work. First, engineers had to obtain a work permit to access Aker BP’s offshore system. Then, they had to use the system to pull up data on each individual valve, going one by one in the slow system until every valve that was scheduled for maintenance during that session had been checked.

Solution

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.

Impact

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.
