ABSTRACT

This paper discusses the use of a simulation based training system by Shell Pipe Line. Components of the trainer system are the simulation software, graphic display software and a pipeline model. The pipeline model was designed to challenge the trainees and be representative of Shell. pipeline systems. The training course begins with basic hydraulic training and familiarization with the training simulator. Controllers observe the operation of the training simulator by watching the three display monitors, two of which are similar to actual control consoles. The remainder of the course consists of release exercises in which the instructor will start a release. The trainee will then use information available to him through the display monitors to spot the release and then estimate its size and location. Training Oil Hovements Controllers at Shell

INTRODUCTION

There is increased concern about pipeline releases by the public, government and industry. The focus of this concern is often the people operating the pipeline; the controllers. Most pipeline controllers have never seen an actual release while operating a pipeline. while this fact reflects positively on the safety of the pipeline industry, it does mean that the people who must react to a release may have little or no experience with this type of situation. Further complicating the controller's job is the fact that a release may appear quite different depending on the size and location of the release, as well as pipeline operating conditions at the time the release occurs. This paper discusses the use of a simulation based training system in the context of controller training at Shell Pipe Line. The training system itself will be described, but the focus will be on how the system is used to improve the abilities of controllers to detect releases. Shell's Trainer System Shell s trainer system consists of computer hardware, simulation and display software, and pipeline models. Figure 1 shows the functional relationship between the various components of the trainer system.

Hardware

The hardware part of the trainer system consists of a VAX model 8250 computer and three Tektronix model 4211 color graphics terminals. All of the trainer related software runs on the VAX computer. This computer is used because it was available for this application. The color graphics terminals are used as the interface between the trainer system software and the trainees and instructor. The particular Tektronix models were chosen because of their compatibility with the trainer system software, and for their screen size (19 inches) and expandable memory. Function keys on the terminals were programmed to better approximate the actual displays used by pipeline controllers at Shell.
