In the realm of industrial training for the oil and gas sector, Virtual Reality (VR) technology is employed to enhance safety, efficiency, and cost-effectiveness. Traditionally, training subsea engineers posed challenges due to the high costs, time-consuming nature, and ineffectiveness of conventional methods.

Travancore Analytics (TA) developed a Unity-based VR training application aimed at simulating real-world scenarios for repairing broken subsea gas pipelines. The VR experience begins with a briefing in a diving bell, where users are prepared for the mission to repair the pipeline using necessary tools and controls within a habitat. The client, a prominent player in the oil and gas industry, faced challenges training subsea engineers due to the remote and hazardous nature of pipeline operations. Additionally, traditional training methods were costly, time-intensive, and sometimes ineffective in imparting necessary skills.


1. Inefficient and time-consuming traditional training approaches.

2. Limited availability of training materials and equipment.

3. Difficulty in practicing real-life scenarios due to safety concerns.

4. Complex procedures leading to knowledge retention challenges among engineers.


TA devised an immersive VR training solution tailored for subsea gas and pipeline repair. The Unity-based application recreated realistic underwater environments, allowing engineers to practice repairs virtually using identical tools and procedures as in real-world scenarios. The VR environment includes Gas Containment Barriers (GCB), Stand-off Sleeves, and a toolbox with tools like electric torque wrenches and welding machines. Engineers commence training inside a dive bell, receive a mission briefing via video, and proceed to the habitat for repairs. Tasks involve installing GCBs, securing them with nuts and bolts using tools from the toolbox, and welding Stand-off Sleeves. Voice and text instructions guide users throughout the process, ensuring correct execution and efficiency.


The VR training solution significantly transformed the client’s training program:

1. Enhanced efficiency and reduced errors during actual pipeline repairs.

2. Provided a safe and controlled environment for hands-on training.

3. Improved retention of complex procedures among trainees.

4. Decreased overall training time and costs.

In conclusion, VR technology offers a promising avenue for industrial training by simulating hazardous scenarios in a safe environment, improving learning outcomes, and optimizing training costs. As VR technology evolves, its integration into various industrial sectors is expected to grow, revolutionizing training methodologies and preparing employees more effectively for real-world challenges.
