The oil and gas segment in particular has significant challenges. Many upgrade, refur- bishment and maintenance projects involve hundreds of workers who must be thor- oughly trained – especially in safety-related operations such as handling fires, toxic chemicals, high-pressure leaks and other emergency incidents. Scheduling requires precise choreography to ensure each step occurs on time and in proper sequence. A growing number of companies in the pipeline and gas industry are addressing these challenges through the use of 3D vir- tual planning, simulation and visualisation technologies. Such systems allow people to plan and schedule operational procedures, train workers and meet health and safety requirements by interacting with a com- puter-simulated 3D environment, including cranes, plant assets and workers to deter- mine the best process to minimise costly pro- ject delays and mitigate risk. By studying procedures in this virtual world, engineers, planners, safety experts and workers can identify problems, explore options and determine the best remedy with- out disrupting actual plant operations. With lifelike 3D models, simulations and visuali- sations, planners can test their project plans virtually, and workers can see precisely what they need to do before they attempt it on the job. In this manner, optimal procedures and scheduling of operations can be worked out before projects are started in the plant or along the pipeline and workers can be safely trained off-site. Traditional ways of planning rely on the experience of workers and subcontractors to execute the required maintenance tasks, sup- ported with 2D information. But 2D drawings and historical information are oen inaccu- rate and outdated, leading to miscommuni- cations between the various project teams during the actual execution. This results in expensive delays to the project, unsafe work- ing conditions and costly project rework. 3D simulation-based systems for planning scheduled maintenance or new operational procedures provide an effective way for engi- neers to develop precise and detailed plans to execute work right-first-time by studying various scenarios and performing "what-if " evaluations well before tasks are attempted. In advanced systems, scheduling so- ware is oen coupled with process planning simulations in an integrated solution that optimises schedules for day-to-day plant operations as well as periodic maintenance tasks. By iterating with process planning in evaluating various what-if scenarios, the scheduling solution analyses alternative sequences and arrives at an optimised mas- ter schedule. This output is invaluable to project managers and others in determining budgets, manpower requirements, critical timelines and operating efficiencies. Virtual reality (VR) training systems cre- ate a lifelike, immersive environment that adds another dynamic dimension to 3D sim- ulations. VR enables users to interact with computer-simulated equipment and sur- roundings with lifelike realism. Most of these applications are used in worker training, where some of the most advanced systems use 360-degree wrap- around theatres with photo-realistic imagery viewed with stereoscopic glasses. Multiple speakers generate high-fidelity sound effects to familiarise workers with the harsh and sometimes subtle sounds found on job sites, which might include a variety power plants, transmission hubs or treatment works. Head-mounted goggles track head and eye movements, allowing the system to rec- ognise where users are focusing their atten- tion in the overall scene. In this way, workers can be trained off-site using VR without dis- rupting normal work routines or exposing them to the real hazards. In any of these systems, different mainte- nance and operations scenarios can be per- formed without workers being on the actual site. Another benefit is that workers can familiarise themselves with sites – poten- tially before they exist in the real world. Workers can learn specific operations and maintenance procedures so they are immediately productive. A report issued at the end of virtual reality training indicates which tasks were successfully performed and which mistakes were made, so employ- ees can be coached on individual skills while the company is able to create regulatory documentation. Companies in the energy industry are leveraging simulation technology to ensure workers are well prepared with the skills and knowledge necessary to work safely in an unforgiving environment. These organisations are increasing productivity and lowering costs by better planning operations and maintenance proce- dures, maximising workflow and utilisation of resources with detailed and co-ordinated scheduling, and making plants safer and more efficient with comprehensive simula- tion-based training. The business value of these applications is immense in reducing the costs of non- productive time measured in hundreds of millions of pounds annually and avoiding the billions lost every year in this complex industry due to operating inefficiencies.

It's time more utilities took advantage of the technology, says Stephen Chadwick. Key points • Utilities under multiple pressures to implement new technologies with an ageing workforce can benefit from virtual reality training applications. • Training staff in virtual environments can reduce risk in terms of damage to equipment or injury to staff. • It allows for multiple and worst case scenario demonstrations. • VR training can increase worker pro- ductivity by increasing right-first-time job completion. • VR allows for training on sites that do not yet exist in the real world but which have 3D modelling information. • VR training can save significant sums of money through increasing operational efficiency.
