When a ship is approaching a dangerous situation, ECDIS serves as an appropriate alarm to warn the watch officer to prevent marine accidents on the ship’s bridge. However, it has been reported that watch officers who believe that frequent mechanical alarms are causing fatigue and interfering with the watchkeeping are ignoring or turning off the alarm. Alarms are used in a situation requiring attention. In this context, the study examined the advantages and disadvantages of the abstract sound, the auditory icon, and the voice output as an audible alert to watch officers who are in a complicated situation to focus on. In addition, watch officers’ response time was measured according to the alarm types. As result, a new type of alarm set that combines the abstract sound that gains more attention and the speech output that directly expresses information concerned is proposed for the improved ECDIS audible alert recognition by navigation officers. Additionally, amendments to the relevant ECDIS performance standards were also proposed.","PeriodicalId":261809,"journal":{"name":"Journal of International Maritime Safety, Environmental Affairs, and Shipping","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133083150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to gain important insights into risk levels of those fuels associated with bunkering, accidental fire/explosion scenarios were developed, and the potential risks of those adverse situations were quantified. The results were interpreted as a form of the levels of safety zones applicable for bunkering. As the first attempt to compare the risk of two promising marine fuels, this paper is highly believed to give some meaningful insights into proper understanding of risk levels, thereby establishing safety practices and conducting future regulatory frameworks to mitigate those risks accordingly.","PeriodicalId":261809,"journal":{"name":"Journal of International Maritime Safety, Environmental Affairs, and Shipping","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121799802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These changes were prompted due to lacunas in the legal system, which surfaced when the codified laws were implemented. The problem of maritime piracy flares up every few years, especially with the modernization of boats and weapons. Dealing with maritime piracy involves coordinated and orchestrated efforts at different levels including, domestic, regional and international. Anti-maritime piracy operations have been very successful in controlling and reducing piratical activities, for example, attacks on merchant vessels off the Somalian coast have considerably reduced. Given the success of such anti-maritime piracy operations, it becomes imperative to underscore some legal issues that may stand out and flag the gaps in the international maritime piracy legal regime. Identifying such legal issues will help the future lawmakers in deciding if such issues need resolution, and does it require further development or amendment of the current maritime piracy legal regime.","PeriodicalId":261809,"journal":{"name":"Journal of International Maritime Safety, Environmental Affairs, and Shipping","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133403396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This important factor can shorten the design life of a ship by increasing the possibility of structural damage. One way to improve the reliability of the fatigue life of a ship is to check for fatigue damage by observing real-time stress response depending on marine environmental conditions. Modern stress monitoring systems are installed in critical spots to capture stress signals and used to minimize the risk of crack occurrence. In the present study, a hull residual life prediction procedure was introduced by integrating traditional fatigue analysis and the stress response obtained from strain gauges installed in the hull. A three-cargo-hold oil tanker model was used to calculate the residual fatigue life using Harmonized Common Structure Rules (CSR-H). For evaluation, data obtained from the strain gauges and predicted data using a deep-learning technique were compared. According to the results, this process could be applicable to predicting residual fatigue life during a ship’s operation in real time if a long period of statistical data is available. The developed techniques can help analyzing the fatigue integrity of operating ships and ship equipment.","PeriodicalId":261809,"journal":{"name":"Journal of International Maritime Safety, Environmental Affairs, and Shipping","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121287475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a chaotic secure communication scheme by using observer design for maritime navigation and transportation systems. The proposed scheme involves three key factors: chaotic encryption, state observer, and chaotic decryption. The chaotic system, as the encryption keys carrying confidential information, will be sent from transmitter to the receiver through a public channel. It is obvious that the fewer signals are transmitted on the public channel, the higher security of the communication system is possible. A state observer is designed to estimate all system states when only partial states are detectable on the public channel. The robust observer gain is implemented in terms of linear matrix inequality (LMI) for convex optimization. The process of information encryption and recovery has been discussed in detail. From the simulation results, it is found that the observer-based method can robustly estimate full state variables by using system output signals with LMI optimization. Based on these updated states with the the state observer, the original information is accurately recovered for safe navigation of vessels with reliability and efficiency.","PeriodicalId":261809,"journal":{"name":"Journal of International Maritime Safety, Environmental Affairs, and Shipping","volume":"445 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123431263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This results in a range of outcomes ranging from minor consequences, when winds blow persistently offshore, through to a worst case where oil is brought ashore in larger quantities and in many locations. Often modellers resort to identifying a “worst case” which might be the run when oil reaches shore soonest, or when the most oil washes ashore [5], [6]. However, it is well known that damages and costs of clean-up vary spatially by shoreline type and activity [7], [8]. So how can decision makers be confident that the so-called “worst case” selected by these methods is in fact a worst case. And in any case, is the “worst case” an appropriate basis for setting financial assurance amounts. The researchers explicitly addressed these uncertainties in a novel way for oil spill damages assessments, by providing a cumulative probability distribution of outcomes, with each outcome representing the total damages from a particular spill event. An automated method using oil pollution damage models was developed and applied to enable this approach.","PeriodicalId":261809,"journal":{"name":"Journal of International Maritime Safety, Environmental Affairs, and Shipping","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129258756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
