Abstract
The objective of this paper is to determine the level of Vessel Traffic Services Operators' (VTS-Os') Mental Workload (MWL) by using NASA Task Load Index (NASA-TLX). For this purpose the questionnaire is prepared and submitted to the Turkish VTS Operators (in the Istanbul and Canakkale VTS Centres) who has a long term sea experience as a Ship Master and submitted to the Japanese VTS-Os in the different locations (Akashi Strait, Bissan Seto, Kurushima and Kanmon Straits). The VTS-Os' MWL is subjectively determined by using NASA-TLX because of its origin that includes the operators judgements. In the analysing part, MWL of the Turkish and Japanese Operators are compared and also the relationship among the different safety culture of VTS-Os and their characteristics are investigated. The results show that there is not any significantly difference between Turkish and Japanese Operators' MWL, and the MWL is independent from operators' profile variables such as; age, marital situation, sea experience, experience at VTS Centre and educational level.
