SITUATION AWARENESS AT SEA-VESSEL TRAFFIC SERVICE SUPPORT

摘要

Influence of Human Element in shipping industry is rapidly increasing. Human error costs the maritime industry $541m a year, according to the UK P&I Club. From their own analysis of 6091 major claims (over $100,000) spanning a period of 15 years, the Club has established that these claims have cost their members $2.6bn, 62% of which is attributable to human error, NI[1]. More serious and egregious attributions involving SA occur when "Bridge or Shore based Personnel" error due to loss of SA" is listed as a cause of accidents, M.R. Grech et al[2]. The results from maritime operations literature survey revealed that 71% of human errors were Situation Awareness related problems. SA,from the view point of VTS operator, includes some Human Factors (psychological constructs), but we concentrate in this paper on navigational aspect and one of them is assessment (measuring) of navigational situation in certain area, which is highlighted and investigated in the proposed paper. The techniques to measure the situation closeness to approved standard from the view point of safety level are proposed.
