USING HAZOP TO IDENTIFY AND MINIMISE HUMAN ERRORS IN OPERATING PROCESS PLANT

摘要

This joint paper between Tracerco and ABB outlines some of the benefits from carrying out a HAZOP Study focusing on Human Interaction with process plant.Tracerco wished to conduct a hazard study of their existing High Pressure Injection System (HP Injection Rig) to understand how to improve the design and minimise the impact of human errors when operating the system. The HP Rig is used to inject tracer material into a client's process to allow measurements to be taken. The Rig can be used to inject liquid into a dual phase flow line, liquid into a gas line or liquid into a liquid line.Traditional HAZOP is good at checking the hardware design for an existing system but is best adapted if you are aiming to identify and minimise the potential for human operational errors.By using this approach, this paper highlights some of the simple, practical, low cost measures that were identified during the study, to improve the design and also minimise the possibility of human error when operating the HP Injection Rig.
