Alarm flooding is the signalling of a large number of alarms in a few minutes, in such a way that it is impossible for the operator to attend to all alarms. On these occasions, it is usual that the operator leaves the alarm summary list and gets an analysis of the plant through the screens of the DCS (digital control system), seeking to understand the situation. The alarm summary list ceases to be a useful tool. In such cases, the operator might have the aid of a filter that would present the highest priority alarms and other information associated with them, enabling him to gain a better knowledge of the situation. This paper describes the interface of a system aimed to help the operator to have a more comprehensive knowledge of the process (a better situational awareness) during process upsets that cause alarm flooding, recovering the utility of the alarm layer to the safety of industrial processes.展开更多

As a descriptive study, it explores the written communicative events produced by engineers in the petroleum industry in Malaysia. Language use is commonly analyzed for competence and performance. Competence is best described as the internalized linguistic knowledge as acquired by the learners while the notion of"performance" is best defined as the external evidence of language competence. Therefore, the core of this paper is reflecting actual language use of the language learners in Malaysia. The data are drawn from a sample corpus compiled from the written communicative events in three companies of the petroleum industry in Malaysia. The methodology applied is fundamental as it tends to investigate the linguistic constitutions in the genre-specific corpus of the professional discourse produced. Computer-based syntactical studies are limited as they require hard work and long hours in order to key-in the data and then there is the complex analytic method of describing the findings. In contrast, this paper will demonstrate an uncomplicated method of analysis and also encourage the use of existing POS (part-of speech) tagging software available online.展开更多
文摘During the operation of complex process, such as oil production or refming, abnormal situations may occur, leading to an alarm flooding.
