The Environmental Effects of Projected Container Terminal to the Safely Manoeuvring

Yurtören C., Duru O., Satir T.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2008

Vol. 2, no. 1

93--97

This paper investigates vessel traffic risks that are exposed by a new port installation. A vessel traffic risk analysis was performed by the Ship Handling Simulator team for container terminal installation in Izmit Bay. The main purpose is to evaluate whether the container terminal project shall affect the proper operation of nearside Oil Refinery Terminal. Construction and revision of shore structures may form significant threats for masters in ports and narrow waterways. The Ship handling simulator of ITUMF presents the environmental objects’ effects, vessel traffic and weather conditions. Furthermore, the Environmental Stress Model of Inoue (2000) may give an opportunity to analyse vessel traffic risks quantitatively by SHS.

Mental workload of the VTS operators by utilising heart rate

Kum S., Furusho M., Duru O., Satir T.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2007

Vol. 1, no. 2

145--151

This study clarifies the mental workload of VTS Operator; by understanding their characteristics during carrying out their task, with a physiological index. The objective is to determine VTS Operators’ mind stress that might trigger any human error based on their mental workload during their watches. For this purpose, Heart Rate Monitor (HRM) is utilized as physiological index. The VTS Operators fitted the HRM and all of them have experience as a Master Mariner. During the all experiments, their heart rates and behaviours were recorded on the Event Record Form based on the time scale. After getting the heart rate variability, it is matched with the events, and then Operators’ behaviour is understood as the mental workload due to such kinds of events. Furthermore, these workloads include the Operators’ mind stress and their decisions under these circumstances. This study provides the fundamental information for understanding the VTS Operators’ characteristics.
