One of the biggest challenges in the oil and gas industry is maintaining safety in a hazardous and complex environment. Digitization can help address this challenge in two ways. First, digitization can monitor equipment conditions in real-time using the Internet of Things (IoT), so that damage or accidents can be detected and prevented before they occur. Second, digitization can use big data for risk analysis, so that factors that can cause incidents or losses can be identified and reduced. However, digitization also poses new challenges, such as security and reliability of the systems and technologies used. Therefore, it is important for the oil and gas industry to ensure that the digitization systems and technologies applied have high quality and security standards, as well as involving and training workers to adapt and utilize digitization optimally.
