Opis:
Marine accidents are caused by complex and diverse causes. Therefore, it is necessary to analyse accidents from the perspective of the whole system rather than the existing analysis models that focus on cause-effect. The STAMP analysis is a constraint-based model that focuses on improper management or enforcement of safety-related constraints in system operation. Thus, as a case study of the application of the STAMP technique in marine accident analysis, the Milano Bridge pier contact accident that occurred on April 6, 2020 in Busan New Port of South Korea was analysed by the STAMP technique in this study. Through this study, it was proposed to break away from the domestic accident investigation, which focused only on the punishment of the ship operator, and to suggest improvements that enable organizations related to the marine accidents to take initiative to take efforts for safety.

Opis:
The year 2022 was marked by economic risks with potentially very sensitive impacts for countries in the Black Sea region. Given the limited capacity of Ukrainian ports, as well as the sanctions imposed on Russia, due to ongoing conflict, it was necessary to identify new destinations capable of taking over the flow of goods that normally went to the countries involved in this conflict. In addition to the risks specific to maritime transport, the risk of armed conflict comes with new challenges that can also materialize in the form of environmental impact. To analyze this potential impact, the study is being focused mainly on the analysis of the pollution risk generated by the emissions caused by the vessels calling the container terminal CSCT, located in Constanța harbor, and the emissions generated by the vehicles moving in the terminal. As estimated from the start all levels of pollution have increased, with the level of CO2 increasing from 11072.7 tons in 2021 to 11915.7 tons in 2022. The NOx emissions have a similar trend, as well as the other emission level measured and calculated.

Opis:
This article considers a new method of decomposing the ship route into global and local planning using MATLAB and Simulink developed by the authors. The authors propose to create a program code in MATLAB and operate it into Simulink. Wherein, the corrective coefficients were written in MATLAB. Such trajectories are constructed as a set of points, collected into the special matrix. In determining of the angle value of the rudder was used the ship’s turning ability such as: high (HG), middle (MD) or low (LW) with regard to passage area. Moreover, in the article were analyzed and calculated the ship rudder effectiveness for Proportional-Integral-Derivative (PID) control. The paper is devoted to the problem of safety navigation. First of all is the task of planning the path: the trajectory of the vessel’s movement in the local water area. The purpose of planning the vessel trajectory in the local water area is to ensure navigation safety due to marine traffic and environmental conditions. One of the tasks of the present work is controlling following a desired trajectory. The article notes affect of the vessel motion deviation into control process.

Modern industries often attempt to implement innovations that have a disruptive potential. In shipping, this included a largely unsuccessful introduction of nuclear propulsion in late 20th century, among other concepts. Nowadays, introduction of increased autonomy is being associated with prospects of various industry-wide benefits, but is also burdened with serious obstacles. The objective of this study is to investigate reasons behind the failure of nuclear-powered merchant ships introduction and whether lessons learnt from it can be applied to the prospective implementation of autonomous merchant ships. It advocates that three aspects of maritime technology are crucial for its successful implementation: perceived level of safety, economical feasibility, and legal setup.

This article aims to investigate the contemporary challenges of electronic navigation and assess the appropriate amendments should autonomous vessel technology becomes widespread in the near future. Vessel control systems and maritime communication are essential and sending and receiving alarm signals is critical to contemporary ship navigation. Numerous location and shipping information systems, such as GPS, Loran-C, and Decca, have arisen in recent decades to improve navigational safety. Other systems, including VHF and Inmarsat, have been developed to enhance the efficiency of maritime communication on board and to transmit risk and safety-related data. Additionally, safe navigation requires systems like Navtex, EGS, DSC, Epirb, and others [1].

This paper explores concerns regarding the design, implementation, and management of alarms in DP vessels that, while in operation, need an incredibly high level of accuracy along with high reliability and safe operations. The Human, Technological, and Organizational factors (HTO) method is primarily used as analysis tool to find weaknesses in alarm handling during DP operations. The research focuses on results collected from Dynamic Positioning Operators (DPO) and instructors. Findings from the survey are presented and compared to the results from past accidents and technical requirements from Petroleum Safety Agency Norway via YA 711. Three accidents from past are referred to picturize the findings from the survey results. Furthermore, the conclusion is given with recommendations reflecting the findings from the survey. The main findings are an urgency to establish a centralized marine accident investigation system which enforces learning and recommendation to make operations safer. In addition, the survey also suggests that prohibition of clients or limiting their access to the bridge is necessary. Manufacturers could focus on research and development of alarm prioritization, on structuring and presentation, and profiting by taking feedback from end-users to make DP operations safer.

Opis:
The inflatable liferaft layout applied to passenger ships for the effectiveness of the evacuation process must be based on IMO MSC.1/Circ. 1533 regulations with the maximum evacuation duration is n ≤ 60 minutes. Based on the data from KNKT, in 2021, sea transportation became the biggest contributor to accidents with 342 people dying and missing. Liferaft is one of the main safety tool used during an emergency to save the people and leave the ship. This study used Thunderhead Pathfinder software which was Agent Based Evacuation Simulation combined with 3-D simulation results. The modeling was conducted with two types of layout liferaft and two scenarios of dangerous conditions, the first was a fire in the engine room and the second is the ship experiencing a 20° of heel. The results of this study indicate that there was a difference in the total evacuation duration between the existing layout and the layout that has been changed according to the writer's suggestion. In fire conditions there is a difference of 1 minute 18 seconds in case 1, 1 minute 16 seconds in case 2, 1 minute 38 seconds in case 3, and 22 seconds in case 4. In the heel condition there is a difference of 1 minute 19 seconds in case 1 and 1 minute 25 seconds in case 2. The results of the evacuation simulation modeling with the liferaft layout on the navigation deck that have been modified according to the writer’s suggestion in all cases are getting a value of n ≤ 60 minutes and also have complied with the IMO MSC.1/Circ. 1533 regulations.

Strong expansion of cruise ships traffic and cruising destinations in the Adriatic makes the region ideal for cruise ships routing analysis. The aim of this paper is to detect real cruise ships traffic movement in order to understand how present cruise ships routes are navigationally and environmentally sustainable and safe. Cruise ships characteristic operational demand and navigational routine in relation with regions indented coast line with high level of environmentally preserved areas in landscape of high national value, emphasise importance of real cruise ships routing awareness. The research is based on one year cruise ships traffic monitoring and routes analysis in the Central Adriatic East coast. The results offer detail insight of cruise ships navigational routines in navigationally less defined area that has not been frequent cruising region before. Cruise ships routes comparison is carried out between North Adriatic region, which is well defined with traffic separation schemes and navigational aids and less defined Central and South Adriatic regions. The results show that principle of cruise ships routing differ from standard maritime practice and that operational demand for attractive cruising and passenger experience bring cruise ships close to shores in various demanding navigational situations. That routing practice does not meet criteria of sustainability as it often present high navigational, safety and environmental risk.

Opis:
Autonomous and remotely controlled ships present new types of human factor challenges. An investigation of the underlying human factors in such operations is therefore necessary to mitigate safety hazards while improving operational efficiency. More tests are needed to identify operators’ levels of control, workload and stress. The aim of this study is to assess how increases in mental workload influence the stress levels of Shore Control Centre (SCC) operators during remote ship operations. Nine experiments were performed to investigate the stress levels of SCC operators during human-human and human-machine interactions. Data on the brain signals of human operators were collected directly by electroencephalography (EEG) and subjectively by the NASA task load index (TLX). The results show that the beta and gamma band powers of the EEG recordings were highly correlated with subjective levels of workload and stress during remote ship operations. They also show that there was a significant change in stress levels when workload increased, when ships were operating in harsh weather, and when the number of ships each SCC operator is responsible for was increased. Furthermore, no significant change in stress was identified when SCC operators established very high frequency (VHF) communication or when there was a risk of accident.

Opis:
The Strait of Istanbul, 17 nautical miles long, is one of the main routes of international maritime trade. Connecting the Black Sea countries with other countries of the world, the Strait is the second busiest waterway in the world in terms of international ship traffic. In addition to busy sea traffic, limited geographical conditions also make it difficult to navigational safety. The Strait of Istanbul is the only chokepoint that stands out with the risk of maritime accidents on the primary routes of world maritime trade. This situation poses a risk for both the transiting ships and the city of Istanbul, which has a dense population around it. Some of the accidents that took place in the recent history have caused worldwide concern due to the environmental pollution they cause. Considering the advantages provided by the developing shipbuilding technology and today load capacity of the ships, a disaster that will occur in a possible accident today will cause much greater destruction than in the past. In this direction, it has become a necessity to examine the accident profile in the strait in order to develop effective accident prevention measures and to strengthen the level of navigational safety in the region. In this study, maritime accidents that occurred in the Strait of Istanbul over a 16-year period were discussed in terms of their types and the response time of tugboats to a possible accident was examined.

Opis:
This research is focused upon the evaluation of safe berth clause pursuant to US law, in conjunction with UK law, based on the recent US Supreme Court ruling over “ATHOS I”, which was fixed pursuant to an ASBATANKVOY charterparty to carry a cargo of heavy crude oil from Venezuela to Paulsboro, New Jersey. The dispute arose during the final stretch of the voyage, as the vessel entered the Delaware River, an uncharted abandoned ship anchor ruptured the vessel’s hull causing 264,000 gallons of oil to spill. The Oil Pollution Act 1990 required the Owners to fund the clean-up costs in the first instance (limited to US$45 million) and the US Federal Government’s Oil Spill Liability Trust Fund reimbursed Owners for an additional US$88 million in clean-up costs. Owners and the US Federal Government filed suit against voyage charterers for breach of the ASBATANKVOY charterparty safe berth clause. The case went through two trials, and before the Court of Appeals for the Third Circuit twice, before the Supreme Court were asked to determine ultimate liability. The question before the Court was whether the safe berth clause was a warranty of safety, which meant that liability for an unsafe berth would be imposed on voyage charterers irrespective of whether they exercised due diligence. The answer to that question was yes; the language of the safe berth clause in this case was unambiguous and unqualified. The obligation on the voyage charterers was to designate a berth that was free from harm or risk such that the vessel come and go from always safely afloat. The Court went on to comment that “charterers remain free to contract around unqualified language that would otherwise establish a warranty of safety, by expressly limiting the extent of their obligations or liability. In the absence of any such qualifying language however the Supreme Court has made it clear that a charterer is liable to the owner for any consequences arising out of the ship being ordered to an unsafe berth, an obligation unfettered by any issues of due diligence or the degree of knowledge on the part of the charterer.

Opis:
Over the years, many publications have been published on planning ship’s passage through the NSR and input and output data modeling. Results were not considered in terms of errors of modeled output data. Basic research for the years 2008 - 2020 was carried out in the study on opening and closing dates of ice-free transit corridor on the NSR and probable number of tariff zones where paid assistance of icebreakers would be required. Mathematical relationships of average values and probable errors of navigational, ecological and economic ship voyage performance were developed. For this purpose, partial derivatives of functions were used. The outcomes of the study have shown that changes of total average cost of vessel’s transit voyage depends mostly on number of tariff zones where assistance of icebreakers is required. But navigation with icebreakers assistance ensures smaller standard deviation of total voyage time and thus more precise scheduling of ship's voyage timetable through the NSR. The higher probability of meeting requirements set by decision-maker when planning a long-term voyage of ship, the shorter time window for meeting these requirements. Outside the favorable time window, the navigational, ecological and economic results of voyage deteriorate very quickly.
