To ensure that operators retain the requisite knowledge and the skills, and that they remain competent to control processes in emergency conditions, companies should provide them with opportunities to develop and sustain their capabilities. He discussed a systematic, five-step approach for implementing operator training simulation over the long term (viz., identification, normal operation, start-up and shut-down, troubleshooting, and optimization) along with feedback from OTS users, and use of operator training simulation to develop applied skills (viz., cooperation, communication, supervision, and situational awareness). Glaser described the need for a systematic approach for implementing operator training simulation to obtain maximum training benefits. Manenti stated that a real plant is no place for training, and prior experience based on dynamic simulation may be fundamental in reducing the impact/damage of accidents or even in preventing them. Hence, there is a need for continuous developing of their skills as their performance has a direct influence on the safety, productivity, profitability, stability, and controllability of the process.Īn OTS takes care of this gap by combining the theoretical training and hands-on practice. Skilled operators are essential for safe plant operation, maximum process performance, reduced environmental impact, and reduction of accidental losses in the complex chemical processes. Reported benefits from OTS include faster startup, improved operations, reduced upsets, and reduced operator errors. Operator training simulators offer one of the best methods to provide this training.

Operators must be trained for emergency situations so that they know how to respond to process malfunctions and other abnormal events. Many industrial accidents occur because of improper training on automation and process equipment, instrumentation, or in safety procedures for operations and maintenance. Why Operator Training Simulators are needed? Storing of data on plant variables, which can be used for postscenario reviews. Snapshots, backtracks, and speed control, Run/pause/resume and load/save capabilities, Training of operators and evaluation of operators’ performance, Monitoring and trending of any plant variable, Scenario creation and imparting malfunctions/upsets into the process model,
Main functionalities of OTS reported by Dudley et al. The main role of an OTS is to replicate process dynamics behavior over a wide range of operations including startup, shutdown, and critical situations. Maintained to remain consistent with the actual process and controls. Used in teaching operators to recognize and react to plant-specific events and scenarios, with an instructor console,Ībility to run exercises without an instructor, Realistic process models to provide the sense for urgency in reacting to training exercise events, High level of realism due to reasonably accurate dynamic process models, Training environment nearly identical to the control room, Same equipment, distributed control system configuration, tags and logic as the actual plant, The components of OTS by Ayral et al include: Why OTS is needed, what are typical applications and challenges for its application in process industry, and what strategies to apply?Īn increasing number of companies are using OTS to train the operating staff on handling different malfunctions, startup, shutdowns and infrequently occurring modes of operation.

Enabling quality training for operators is becoming more and more important as they nowadays need to handle increased load of information and duties while the lack of operators' training is the major reason for their inadequate performance.Ĭonventional training methodologies are not enough to train an operator for seldom-occurring dangerous situations, therefore the operator training simulator (OTS) has become inevitable part of their training where they are able to learn without actually endangering the plant and personnel (Patle et al). A well trained and skilled operator is one of the key elements in increasing the plant's safety and productivity.
