Therefore, identifying the factors causing groundings is essential to reduce their effects and to prevent recurrence. Thus, the principal purpose of this study is to analyse the risks of grounding accidents using an integrated model. First, a fault tree analysis (FTA) was applied to create a risk hierarchy that defines the level of relationship among factors; and a Bayesian network (BN) analysis was conducted to evaluate the level of their effect on groundings. The study found that of the 34 factors related to the safety of navigation, E 10 /violation of COLREG Rule-5 (look-out), E 9 /improper use of ECDIS, and E 8 /improper use of radar significantly effect groundings. The findings also indicate that maintaining a safe navigation watch is crucial to prevent future accidents. This study makes a significant contribution to the relevant literature as one of...

To do this, initially, an interpretive structure modelling (ISM) was carried out to construct the relationship hierarchy of risk factors while a fuzzy Bayesian networks (FBN) were conducted to quantify impact level. The results revealed that liquefaction and improper actions to upright, among 19 factors, have a significant effect on capsizing. The findings also emphasize that the factors (improper loading (29%), lack of cargo care at sea (27.4%) and insufficient knowledge (22%)) arising from human error play an important role in cargo liquefaction. Unlike experimental researches in the literature, this research analyses the liquefaction risk and the other basic causes resulting from the capsizing of bulk carriers using an integrated risk assessment method. For further researches, it is recommended to consider other risk identification and as...

To do this, initially, the emissions as a result of 435 trips of 19 ships engaged in domestic transportation in Izmir Bay were evaluated by the bottom-up method. The spatial distribution map was then compiled using the point density analysis through MapInfo v.16 software as a GIS instrument. The study revealed that annual emissions of PM 10 ,CO 2 ,NO x , SO 2 , and HC from domestic shipping were 601.5 t, 925.9 t, 62612.1 t, 22.0 t, and 61.2 t, respectively. In addition, the highest emissions as ton per daily trip were recorded in the cruising mode due to longer operation periods compared to the other modes. It was found that the lines between Pasaport, Alsancak and Karsiyaka piers are the most polluted routes due to dense ship traffic. Furthermore, Bostanli and Karsiyak...

To get well informed about fate, this study makes the best possible use one trajectory model. PISCES 2 (Potential Incident Simulation, Control and. Evaluation System), has been conducted for simulation of main weathering processes of oil spill. Hence in order to identify the risky areas, two scenarios have been developed depending on the type and amount of pollutants. In this study it is concluded that Yenikale, Inciralti and Guzelbahce will be at risk of contamination in case of accidental oil spill at Yenikale Entrance. Finally, the PISCES 2 software provided highly reliable solutions in evaporation rate and dispersion rate calculations when compared to approaches accepted in the literature. However in the surface area calculations, there is a serious difference between the size of the area calculated by the software and the size of the area proposed by oil spill science.

The city with its great volume of cargo capacity plays crucial role both in international and domestic sea trade. The Port of Alsancak located at the inner part of the bay is the largest seaport of Aegean Region in terms of annual loading capacity. The main objective of this research is to find the root-causes of accidents that have resulted in the groundings in Bay of Izmir. To do this, the Root Cause Analysis methodology was carried out on the accidental data provided by Turkish Main Search and Rescue Coordination Center (TMSRCC). Between 2001 and 2016, a total of 24 ships grounded at the entrance of Yenikale due to shallow water conditions, which is regarded as the riskiest point in terms of groundings. In this study, the Fault Tree Analysis (FTA) method which is the one of the most preferred root cause analysis methods was used. As a result, it was found that equipment failures and geographical factors are the main reasons of grounding accidents in Bay of Izmir. In order to eliminate these causes, necessary precautions have been offered and suggestions for further studies have been made.

In this context the spatial analysis was performed using multiple spatial data provided by Turkish Main Search and Rescue Coordination Center (TMSRCC). A total of 130 ship accidents involving 9 different ship types were included to carry out risk assessment process. The location distribution of ship accidents was analyzed with MapInfo 8.0 software, and then risky areas and risk levels were identified in accordance with the accident frequencies. It is concluded that the accidents frequently occur in yachts and listing/capsizing are the most frequent accidents. As a result, Bodrum and Fethiye have been identified as very high risk (VHR) zones depending on the number of ship accidents.
