Determination of critical risk factors that prevent in-ship communication during ship operational processes

In-ship communication is critical for the successful execution of operational processes such as loading, unloading and maneuvering on ships. Interruption of in-ship communication for any reason not only causes these operational processes to fail, but also can lead to serious accidents. In addition, as a result of these accidents, death, injury, damage to ships and port facilities, environmental pollution and legal problems may occur. In this respect, establishing an effective and uninterrupted in-ship communication during ship operations will significantly reduce the risk of accidents. In realizing this, it is of great importance to determine the critical risk factors that create barriers for in-ship communication. In the study, as a result of detailed examination of publications, circulars, safety guides as well as consulting expert opinions, risk factors that prevent in-ship communication were determined. Using these risk factors, a comprehensive survey was created and an assessment of each risk factor was taken by an expert group familiar with ship operational processes. Obtained feedbacks were prioritized by performing Analytical Hierarchy Process (AHP). As a result of the analyzes made, it was concluded that the risk factors that most negatively affect on-board ship communication are due to the lack of training and individual factors.
