This paper presents an evaluation of Formal Safety Assessment framework for cargo ships at coasts and open seas of Turkey. Based on Turkish Under secretariat of Maritime Affairs casualty reports, this study identifies risk factors that have significant, independent effects upon the likelihood of ship and offshore operations. A case study is carried out to determine the most common causes of unintentional damages on cargo ships using FSA. It is obvious that shortage of skilled crew and crew training become very important for safety. This would require a compulsory course related to the human functions such as knowledge of regulations and use of equipment. Finally, some conclusions and suggestions are drawn concerning the needs to reduce the risks and to improve certain safety measures at coasts and open seas of Turkey.

To evaluate and compare the safety level of alternative plans prepared for a towing activity that bears various risks, a novel assessment framework is worked out for inshore towing operations for heavy cargo. The assessment framework mainly includes a set of criteria with hierarchical structure drawn from towing plans and evidential reasoning theory as data aggregation approach. Case study shows that the framework is rational and applicable in the safety assessment of inshore towing operations.

Abstract In maritime safety research, risk is assessed usually within the framework of formal safety assessment (FSA), which provides a formal and systematic methodology to improve the safety of lives, assets, and the environment. A bespoke application of FSA to mitigate accidents in marine seismic surveying is put forward in this paper, with the aim of improving the safety of seismic vessel operations, within the context of developing an economically viable strategy. The work herein takes a close look at the hazards in North Sea offshore seismic surveying, in order to identify critical risk factors, leading to marine seismic survey accidents. The risk factors leading to undesirable events are analysed both qualitatively and quantitatively. A risk matrix is introduced to screen the identified undesirable events. Further to the screening, Fault Tree Analysis (FTA) is presented to investigate and analyse the most critical risks of seismic survey operation, taking into account the lack of historical data. The obtained results show that man overboard (MOB) event is a major risk factor in marine seismic survey operation; lack of training on safe work practice, slippery deck as a result of rain, snow or water splash, sea state affecting human judgement, and poor communication are identified as the critical risk contributors to the MOB event. Consequently, the risk control options are focused on the critical risk contributors for decision-making. Lastly, suggestions for the introduction and development of the FSA methodology are highlighted for safer marine and offshore operations in general.

The study is aimed to assess the navigation safety in the port surrounding the area as part of the Indonesian Government�s efforts to increase the port performance and minimize the cost of maritime logistics. The port navigation system and infrastructure such as vessels traffic management system, navigation lanes, port basin, quay, etc. play an important role in determining the productivity and efficiency of the port, especially in the busy port such as Tanjung Priok, Indonesia. Any accident would interrupt port activities and creates unnecessary costs. Formal Safety Assessment method, as introduced by the International Maritime Organization was implemented in the study. The assessment was carried out using qualitative and quantitative risks analyses, based on the available data and information gathered from various sources. It was identified that accidents occurred in the port waterfront were mainly due to the ships, environment, human factors, and management. Results of the assessment were then used as the basis for proposing an improvement strategy.

Safe production is the foundation of the normal operations of petrochemical enterprises, and it helps maintain social stability. The main purpose of this study is to prevent petrochemical enterprise accidents by proposing a composite safety assessment approach based on the cloud model, preliminary hazard analysis–layer of protection analysis (PHA–LOPA) and the bow-tie model. First, the petrochemical enterprise and its relevant indicators were evaluated based on the cloud model. Second, the quantitative effect of the uncertainty transformation on the evaluation result of the cloud model was further analysed. This mainly includes the error analysis of the numerical characteristics under the conditions of few samples and small values. Third, the critical indicators such as shock and noise can be weakened and prevented by corresponding safety measures based on PHA–LOPA and the bow-tie model. After adopting two independent protection layers, the risk levels of shock and noise decrease from 3 to 2. Then, shock and noise were analysed in depth with the bow-tie model, and the causes and consequences were identified. Moreover, corresponding safety measures were taken to prevent accidents. The case study validated the validity and feasibility of the composite safety assessment approach proposed here.

In India, approximately 30% of road accident fatalities occur on two-lane rural roads. Thus research focused on identifying risk factors on this road type is of immense interest to most of the road agencies. Although these highways are more hazardous and account for more severe crashes, there is a lack of scientific safety assessment of such highways compared with multi-lane highways. Proactive approaches, such as road safety audit, have been widely adopted by the government of India to reduce crash frequency and severity on highways. However, an effective road safety management program should exercise an optimal balance between reactive and proactive strategies to identify potential hazards and treat already existing hazardous sites. Through a case study on two two-lane highways, several risk factors were identified using the principles of road safety audit, and were mapped with the available crash data analysis to develop a risk matrix. This risk matrix was found to be helpful in the selection of countermeasure design in a more scientific way, targeting the frequent crash types and severities expected to result at the high crash sites. Finally, it was observed that integrating the findings from reactive analysis with proactive safety management is more beneficial, since they are methodically proven with historical crash records and provide the knowledge of plausible safety hazards at sites where similar features exist. The proposed methodology could be adopted by road agencies in India and other developing countries for effective proactive safety planning.
