4、neering Equipment and Materials Users Association, more commonly known as EEMUA, is a European non-profit membership Association helping companies that own or operate industrial facilities - the users of engineering equipment and materials. EEMUA aims to improve the safety, environmental and operati

5、ng performance of industrial facilities in the most cost-effective way, thereby demonstrating and pursuing leadership in asset management. EEMUA Members pursue these aims through collaboration for mutual benefit, sharing engineering experiences and expertise and by promoting their distinct interests

6、 as the users of engineering products. Specifically, the aims of EEMUA Member companies are achieved by: providing the organisation within which networking, information sharing and collaboration on non-competitive technical matters can take place; influencing the way written regulations are interpre

7、ted and applied in practice; presenting and promoting Members views, and encouraging the application of good, sound engineering practices; developing user guides, specifications, training and competency schemes; facilitating Members participation in national and international standards making; influ

8、encing relevant national and European legislation and regulations. Formed in 1949 as the Engineering Equipment Users Association, and re-named in 1983 (as a result of taking over the materials association, OCMA), EEMUA has for more than fifty years given companies that own and operate process plants

9、, power stations and other significant industrial facilities, a collaborative voice in addressing technical and engineering related issues that impact on good integrity management and asset management practices. The Association is open to companies of all sizes that meet its engineering user criteri

10、a. Further details of current Members of EEMUA is available on the Associations website, www.eemua.org. EEMUA activities often lead to the production of publications. These are prepared for Members use and are often offered for sale as well. A list of EEMUA publications for sale is given at the end

35、 utilising Human-Computer Interfaces EEMUA ix Foreword Health and Safety Executive Human-Computer Interfaces (HCI) have become an area of increasing focus and importance to the UK chemical and allied industries in the major hazard sector, particularly with the advent of centralised control and the u

36、se of computer screens as key interfaces between processes and the operator. The first edition of this EEMUA guide has been widely used and referred to within the Chemical Industries (CI) sector of the Hazardous Installations Directorate (HID) and has proven to be very useful. The guide is equally r

37、elevant for: other parts of the major hazard sector e.g. offshore; non-major hazard process and other industries where HCI is used as a medium for process and plant control. While the term HCI may sound technical it describes something we are all very familiar with the display screens (VDUs) most of

38、 us increasingly use at home and in the workplace. Its that interface, as used in industrial and process applications, which can be so important in maintaining process and major hazard safety. Issues that may be just irritating to users at home or in the office, may have major safety implications as

39、 we have learnt from many disasters over the decades from the Texaco Milford Haven incident right up to the more recent Buncefield Oil Storage Depot explosion and fires. This guide is a very useful resource for industry, designers, manufacturers and suppliers in the major hazard sector. Inspectors a

40、nd specialists in HID will be looking for evidence that the standards and principles in the guide have been implemented appropriately both for new design, and for ongoing review and continuous improvement - of existing installations. The degree of rigour expected in applying the guide is of course p

41、roportionate to the hazards and risk under control but there are clear business and other benefits to good HCI design and use, as well as safety benefits. The renewed focus on HCI reflects well the current HID and HSE post-Texas City and Buncefield focus on process safety leadership, workforce invol

42、vement and wider human factor issues. Good leadership will help focus on HCI as one of a number of key areas that can influence - and optimise - human performance in the key area of a centralised control room and elsewhere. Good end-user involvement and user-centred design will provide good, workabl

43、e and valued interfaces, including the HCI. I commend this guide to you. Peter Baker Head of the Chemicals Industry Division, Hazardous Installations Directorate, Health and Safety Executive.

44、uation Management Consortium In years past, operators of large industrial processes would perform, monitor and control activities from large panelboards. These contained scores of single loop controllers, indicators with trend charts and alarm annunciators for a limited number of key variables. Beca

45、use of the cost and limited size of the panelboards, project engineers spent considerable effort designing content and layout before implementation. Once built, operators learned the content, where to find things, and a feel for what was normal. At a glance, an operator could get a sense of the over

46、all process status from just about anywhere in the room. Navigation from one part of the unit to another was easy to learn - one simply walked from one location to another. Modern Distributed Control Systems (DCSs) have been justified based on improving control and optimisation, increasing throughpu

47、t, controlling at constraints, and expanding the board operators scope of control. Consciously or not, the demands on operator capability and performance have significantly changed. Indeed, the job of operators has transitioned from one of considerable reliance on knowledge of the plant layout and m

48、emorisation of a number of tasks to one more focused on process knowledge and cognitive skills. Humans are not particularly well suited for watching computer monitors hour after hour, waiting for something to happen which then rarely does. Plant managers and engineers did not fully understand the hu

49、man factors implications of the introduction of this new technology into the control room environment. Inadequately designed graphics for the operators in many cases leads to significantly diminished situational awareness and operator fatigue. The persistent paradox in the process industry is that as automation technology increases in complexity and sophistication, operators face progressively more complex decisions in managing the process. Moreover, the industrys ability to design effective operator interfaces to the process has
