Such systems need to consider interactions among hardware, software, and humans and their potential effects on system performance, which require rigorous testing to verify the system ʹ s safe decision ‐ making ability and operational limits. Testing requirements for verification are aimed at 1) assessing the system ʹ s reliability and failure handling performance, and 2) integration testing. This work uses the System ‐ Theoretic Process Analysis (STPA) to develop integration tests for a novel DSS. STPA is a structured methodology to identify hazards from multiple sources, including hardware or software failures, system interactions, and human errors. The objectives of the study are to develop and assess the feasibility of integration test procedures based on STPA. The stability monitoring subsystem from the DSS is analyzed as a case study. The results are used to suggest functional and performance integration test procedures.","PeriodicalId":46009,"journal":{"name":"TransNav-International Journal on Marine Navigation and Safety of Sea Transportation","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81069252","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}

The safety and efficiency (both ecol ogical and in terms of time) of the winter transport system is highly dependent on the decision -making process followed by the icebreakers. The captains in charge of the icebreakers must decide the priority of assistance among all the merchant vessels that may be in need within a given time window. While captains successfully do this every year, with experience, this decision -making becomes second nature and a transparent picture of how the decisions are made is often missing. It is not always clear what sa lient features captains pay attention to, and how they use those features in their reasoning process to reach a decision during operations. This paper presents a pilot study that uses cognitive task analysis (CTA) to outline captains' decision-making process for ice breaker assistance allocation. In-depth interviews of three subject matter experts were conducted using a naturalistic icebreaker scenario. Results include identified critical decision points, identified, and prioritized salient features, and characterized icebreaker assistance strategies.","PeriodicalId":46009,"journal":{"name":"TransNav-International Journal on Marine Navigation and Safety of Sea Transportation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134982473","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}

To receive the diploma of merchant navy officer, students are required to complete a 12 ‐ month maritime internship. During the internship, as well as during the entire course of studies, students ʹ expectations regarding their future professional work are developed, related to, among others, working and living conditions on a ship, employment conditions and cooperation with the shipowner. These expectations determine the students’ subsequent choices towards a given shipowner as a potential employer, as well as their decisions about further professional development in this field. From the point of view of operational management, it is therefore important for the shipowner to know the requirements that must be met in order to have a motivated and competent staff. This article aims to classify the requirements for students relative to their future work on a ship based on assessing the impact of the requirement fulfilment level against the level of their satisfaction. The results obtained made it possible to indicate those requirements regarding working conditions, the fulfilment of which should be treated by shipowners as a priority, because they determine the students’ satisfaction to the highest degree.","PeriodicalId":46009,"journal":{"name":"TransNav-International Journal on Marine Navigation and Safety of Sea Transportation","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84390475","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}

The effectiveness of some of the integrated track controllers has been tested with free running experiments carried out in the Towing Tank for Manoeuvres in Shallow Water in Ostend, Belgium. The controllers enable a ship to follow predefined random paths with high accuracy. Ship ‐ to ‐ ship interaction is considered in some cases. Simulator environments provide useful tools for extending the number of validation scenarios, supplementing the work performed in the towing tank. The simulator is presented with a graphical user interface, aiming at providing a good user experience, numerous test scenarios and an extensively ‐ validated library of automatic control algorithms. With the usage of the simulator, further evaluation of developed control algorithms by implementing extensive test runs with different ships and waterways could be made. Case studies are shown to illustrate the functionality of the simulator.","PeriodicalId":46009,"journal":{"name":"TransNav-International Journal on Marine Navigation and Safety of Sea Transportation","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78073242","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}
