Technology and innovation
Enbridge has two Technology and Innovation labs. In January 2019, the first lab opened in Calgary, Alberta. In April 2019, the second lab opened in Houston, Texas. The labs use industrial predictive algorithms, machine learning, and sentiment analysis to find efficiencies within the company and help improve safety and reliability of their pipeline infrastructure.
The labs have developed ways to get sensor data from pipelines, helping to improve flows of natural gas and crude oil terminals. Additionally, the labs have helped enhance pipeline leak detection, and ensure better maintenance schedules. For renewable energy projects, the labs have developed different ways to reposition wind turbine blades to help maximize wind power generation.
