The current AIS network is an automatic tracking system used by ships of vessel traffic service for identification and location of vessels by electronically exchanging data between nearby ships and on-shore base station. In the AIS system for the electronic data exchange, the very high frequency (VHF) range is used. Utilizing of the VHF range makes the AIS as short-range communication, identification and collision avoidance system between AIS equipped ships and base station is possible in the antennas line-of-sight . In order to widen the range of the AIS from short range up to long or global range, AIS communication should be used via a satellite. In order to provide communication via satellite as well should be designed multifunctional antenna for both radio AIS (R-AIS) and satellite AIS (S-AIS) communication antenna.

The IMO started implementing the EEXI (Energy Efficiency eXisting-ship Index) and CII (Carbon Intensity Indicator) regulations for the existing vessels on 1 November 2022. The government of South Korea announced a national plan called “the 2030 Greenship-K initiative” to boost the shipbuilding and shipping industries. This plan describes 140 merchant vessels with green ship technologies that will be required for sustainable shipping. The Korean container fleet needs to examine the impact of the IMO regulations through eco-friendly technologies like engine power limitation, energy-saving devices, alternative maritime fuels, etc. It is necessary to select an eco-friendly technology based on the marginal abatement cost for the fleet. Five case studies are considered on which alternative is beneficial for ship decarbonization. The most favorable alternative seems to be an LNG fuel retrofit for the EEXI and CII regulations for the Korean container fleet.

There have recently been a staggering number of fire catastrophes onboard container ships. Investigations have identified that a rapidly developing fire is one of the main challenges in container fires. On the other hand, firefighting regulations had disregarded container vessel capacity increase. The resulting financial losses and environmental catastrophes paid astronomical bills. This research elaborates on an innovative solution utilizing a 5 G wireless self-detecting and extinguishing fire-control system. The system was applied in a case study of 19,870 TEU ultra large-container ships; The results demonstrate the number and locations of the system components. The system can reduce human interference with the fires onboard. The feasibility analysis output shows a low initial cost compared to the losses of such incidents. Moreover, the time of radio spectrum signals of the proposed system is high speed; remarkably, the internal container monitoring needs around 30 seconds to detect heat and another few seconds to activate the CO2 and smother the suspicious container in its early intuition with allocation bothered alarm. The firefighting improvement technology could be a promising solution for monitoring and controlling dangerous cargo containers fire.","PeriodicalId":261809,"journal":{"name":"Journal of International Maritime Safety, Environmental Affairs, and Shipping","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131207968","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 this study, the annual fuel consumption was calculated based on the operation information of 4,151 ships and CO2, N2O, and CH4 emissions among greenhouse gases were estimated. The results of the study showed that CO2 accounted for 98% of the greenhouse gases emitted from ships, the highest, and N2O and CH4 were found to be insignificant at 1.5% and 0.5%. The major types of ships that emitted greenhouse gases were cargo ships, chemical tankers, oil tankers, and gas carriers. Ships subject to data collection system and carbon intensity indicator regulations include only 69% of the fuel consumed by all ships.

Therefore, a plethora of research has already been available in the areas related to the design, production, and operations of ships. However, little progress has been made around end-of-life (EOL) ships. For recycling the EOL ships, the terms “shipbreaking” and “ship recycling” were used in past studies and most of the time these terms can be interchangeably used in different studies. Still, there is a contextual difference that is further discussed. This study compiled the different methods of shipbreaking and ship recycling and the key regulations that facilitate the handling of EOL ships. Furthermore, it assesses the research trends of EOL ships from 1991 to 2021 through a systematic review with bibliometric analysis using the database of Scopus. For the systematic review, the topmost relevant publications are evaluated, and the key findings are compiled to find out the overall status of their contributions to shipbreaking and ship recycling research.

Seafarers suffered immensely as most of their activities were affected due to the lockdown and travel restrictions placed by most governments to protect their borders. This had an impact on mostly their mental health as most of their routine became disrupted, travel plans were cancelled, and some fear of losing their jobs due to uncertainty. This research focuses on the impact the lockdown had on the mental health of seafarers and how it affects their human error probability value during COVID-19 by utilizing the HEART methodology. The conventional HEART technique is not precisely developed to be applied in the marine and offshore sector, so it was imperative to modify it to capture the key factors this research would be measuring which include fatigue, poor communication, depression, sleep deprivation, and how they influence the Human Error Probability (HEP) value of seafarers. To properly factor in these influencing factors, a questionnaire was developed and distributed to expert seafarers to weigh each factor in other to develop the Error Influencing Factor (EIF) table to further boost the accuracy of this research. For this research, the scenario used is a pre-mooring task carried out by seafarers. The result shows that the HEP value changes by over 55% from 6.1676E–2 before covid-19, to 6.1960E–1 during covid-19. Event Tree analysis was also carried out using the individual HEP values to calculate the probability of failure of the mooring ropes. The result shows that the probability of failure during COVID-19 is higher when compared. The application of this modified HEART technique confirms that COVID-19 lockdown had a negative impact on these factors that influence the mental well-being of seafarers.","PeriodicalId":261809,"journal":{"name":"Journal of International Maritime Safety, Environmental Affairs, and Shipping","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131555358","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}

Unfortunately, there is still a disadvantage: there is no holistic approach involved, as the external electrical grid is usually powered by fossil fuels. In a different approach, the zero-emissions port concept uses a smart grid technology framework connected to renewable energy sources and the electrical grid is used only as a backup source in a situation where there is a deficit in power balance. However, an important challenge remains, the conversion to electricity and the efficiency of the converting systems. The use of such sources for commercial electrical supply is only possible with the new “Smart Grid” concept and the use of artificial intelligence (AI).
