Human Factors Affecting the Reliability and Safety of LNG (Liquefied Natural Gas) Facilities. Volume 2. Control Panel Design Guidelines and Checklist

摘要

The principal objectives of this project phase were to (1) expand the relevant human error probability (HEP) data base, (2) develop human factor (HF) design guidelines for LNG control panels and (3) identify research needed to improve HF considerations in other LNG plant systems and operations. Detailed HF design guidelines were developed for work space, labels and location aids, controls, displays, annuciators, gas and flame detectors and emergency shutdown systems. Examples show HF enhancement resulting from application of these guidelines to existing panel designs and the layout of a model panel. A checklist with over 270 checkpoints was developed to facilitate control panel design evaluation. This checklist and the guideline package are of potential practical value to utilities engaged in evaluating or improving HF design of control panels at individual plants. Thirteen projects are recommended to extend consideration of HF effects into other aspects of LNG facility design and operation.
