    Opis:
    The International Maritime Organization (IMO), through its Maritime Environmental Protection Committee (MEPC), has been carrying out substantive work on the reduction and limitation of greenhouse gas emissions from international shipping since 1997, following the adoption of the Kyoto Protocol and the 1997 MARPOL Conference. While to date no mandatory GHG instrument for international shipping has been adopted, IMO has given significant consideration of the matter and has been working in accordance with an ambitious work plan with a view to adopting a package of technical provisions. Beside the efforts undertaken by IMO, it is assumed that e.g. optimized manoeuvring regimes have potential to contribute to a reduction of GHG emissions. Such procedures and supporting technologies can decrease the negative effects to the environment and also may reduce fuel consumption. However, related training has to be developed and to be integrated into existing course schemes accordingly. IMO intends to develop a Model Course aiming at promoting the energy‐efficient operation of ships. This Course will contribute to the IMO’s environmental protection goals as set out in resolutions A.947(23) and A.998(25) by promulgating industry “best practices”, which reduce greenhouse gas emissions and the negative impact of global shipping on climate change. In this paper the outline of the research work will be introduced and the fundamental ideas and concepts are described. A concept for the overall structure and the development of suggested detailed content of the draft Model course will be exemplarily explained. Also, a developed draft module for the model course with samples of the suggested integrated practical exercises will be introduced and discussed. The materials and data in this publication have been obtained partly through capacity building research project of IAMU kindly supported by the International Association of Maritime Universities (IAMU) and The Nippon Foundation in Japan.

    Opis:
    This concept paper described the process of bridging the gaps in one of the methods for determining wheel over point (WOP). WOP is a marking made on charted courses to indicate a point at which a ship should change course. Identifying WOP is vital to avoid the vessel overshooting the planned track. One method for determining WOP is the advanced transfer technique. However, two issues were identified while reviewing this technique. Therefore, an improved mathematical model could be developed to overcome these problems. A manoeuvring analysis using a ship simulator will be performed to test the developed mathematical model's efficacy. The data obtained from the simulation study can be validated further by its adherence to the cross track limit, reduction in percentage change, and using IBM SPSS for the Mann-Whitney U test. The developed mathematical model is expectantly capable of producing a better track-keeping function and suitable for use onboard a cargo ship. The mathematical model also could be implemented as an algorithm in the Electronic Chart Display and Information System to help navigators make more efficient course changes.

    Opis:
    In today’s globalized world, one of the requirements of global supply chains is efficient transportation systems. Approximately 80 per cent of world merchandise trade carried by sea and handled by ports worldwide. For this reason, maritime transport has the strategic economic importance. Loading of oil and gas has the biggest share (%30) in commodities carried by sea and 2.9 billion tons oil and gas loaded to ship in 2013. This study is focus on chemical cargo terminals which is a special terminal form where high and international levels of safety and quality elements applied. Unlike conventional bulk cargo and container cargo operations, chemical cargo operations include own priorities, applications, and the evaluation criteria. The aim of this study is to perform a qualitative research to determine the factors affecting the operational efficiency of ship, berth and warehousing operations in chemical cargo terminals.

    Opis:
    Efficient and effective transport system is the key element for the future development of European economy. Simultaneously, the process of transport development is connected also with the negative effects for environment and society. For that reason, the concept of internalization of all external costs of transport is developing in European Union. The concept characteristics and specificity in the maritime transport is the main issue of the following analysis. The special interest is focused on the maritime safety, one of the key external cost category.

    Opis:
    The continuing surge in commercial vessel sizes is putting increasing pressures on the world’s port authorities to adopt effective expansion strategies to ensure that their asset is able to meet growing capacity demands. Among the key challenges is to assure that correct strategic planning and operational measures are adopted to guarantee safe and efficient traffic not only through its shipping channel, but also at the port berthing facilities. DHI and FORCE TECHNOLOGY have collaborated to develop a novel physics-based vessel traffic management system named NCOS ONLINE. It is capable of taking into account of any relevant vessel constraints such as under-keel clearance (UKC), maneuverability and berth configuration that may constrict the movement of vessels through the channel or operability at berth, facilitating scenario planning and capacity assessment of proven unparalleled accuracy. The system incorporates the accuracy of high-end Full Mission Bridge Simulators with regards to vessel response under power and at berth. The underlying computational engines uses a powerful 3D panel method for vessel response calculations in combination with highly detailed environmental data such as wind, waves and hydrodynamics (water level and currents) simulated by use of MIKE Powered by DHI’s recognized and scientific based computational models. The modular and integrated framework-based system has already been adopted by numerous port authorities, terminal operators and pilots worldwide for strategic port planning, design and 24/7 operational vessel traffic management. The paper focus on presenting the underlying equational framework and validation of the underlying physical response engines and provide a brief introduction to how they are integrated and operated through a series of user-friendly web dashboards.

    Opis:
    Optimal ship tracks computed via the VISIR model are compared to tracks recorded by the Automatic Identification System (AIS). The evaluation regards 43 tracks in the Southern Atlantic Ocean, sailed during 2016-2017 by different bulk carriers. In this exercise, VISIR is fed by wave analysis fields from the Copernicus Marine Environment Monitoring Service (CMEMS). In order to reproduce vessel speed loss in waves, a new methodology is developed, where kinematic information from AIS is fusioned with wave information from CMEMS. Resulting VISIR tracks are analyzed along with AIS tracks in terms of their topological features and duration. The tracks exhibit quite diverse topological shapes, including orthodromic, loxodromic, and other paths with complex and dynamic diversions. The distribution of AIS to VISIR track durations is analyzed in terms of several parameters, such as the AIS to VISIR track length and their Fréchet distance. Model features of VISIR affecting the results are discussed and future developments suggested by the results are outlined.

    Opis:
    Modern ship bridges are highly-automated man-machine systems. Safe and efficient ship operations are dependent on the communication between humans and machines. This paper is dedicated to the general subject of integrated navigation and the specific field of the alert management on a ship's navigational bridge. It deals with investigations into the present situation on board of ships regarding the frequency and type of triggered alarms under real conditions. The conduction of empirical field studies is introduced and some of the gained results are presented and discussed. Finally the alert management concept of the performance standards for Integrated Navigation Systems (INS) is introduced and an approach for the reduction of CPA/TCPA alarm frequencies within INS/IBS is described.
