    Opis:
    Previous research in the domain of maritime energy efficiency has mainly addressed concerns regarding individual experiences and organizational barriers. Reflection on the reciprocal human-technology relationship, interaction design and its impact on the practitioners’ learning and organizational decision-making process is rather scarce. Informed by focus group interviews, this paper describes the essence of practitioners’ activities and the nature of interaction design and proposed improved design for energy efficiency monitoring systems. Findings suggest knowledge sharing for a mutual understanding onboard ships is critical to energy efficiency. Learning can go beyond the embodiment of individual cognitive change but becomes a collective and collaborative achievement mediated by technology, which informs opportunities for interaction design. The design needs to consider the context in which knowledge mobilisation occurs and facilitate collaborative learning. With more intelligent systems introduced to the shipping industry, it is important to consider the impact of mediating technologies in management practices and mediating technologies can be integrated into a broader collaborative learning paradigm emerging between the ship and shore. This study highlights those social-cultural dimensions important to establishing a common ground between practitioners, management and advanced technologies.

    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:
    In order to reduce the CO2 emission from ships, International Maritime Organization executes the restriction of Energy Efficiency Design Index (EEDI) which limits amount of CO2 when freight of one ton is carried at one mile. Although the realization of higher efficiency of main engine without reduction of engine output is the best solution, it might be impossible. To comply with the EEDI requirements, it is assumed that the ship’s engine power becomes smaller than the existing ship by means of improving the ship propulsive efficiency. However, shiphandling in rough seas is expected to become difficult when the engine power is reduced. In this paper it is shown that the influence of the degraded main engine exerts on the safety of shiphandling in heavy weather based on the simulation study. In these experiments, both the simulation model that decreased engine power corresponding to EEDI requirement and that with the conventional engine power were tested, and masters in active service maneuvered the test ships in the rough seas.

    Changes in Oil Transportation
    Opis:
    This paper covers the current state of maritime oil transportation in the Baltic Sea and the development of oil transportation in the 2000s, as well as estimations of transported oil volumes in 2020 and 2030 in the Gulf of Finland. The scenarios were formulated on the basis of a current state analysis, energy and transportation strategies and scenarios and expert assessments. The study showed that the volumes of oil transportation in the Gulf of Finland will increase only moderately compared to the current status: 9.5-33.8 %, depending on the scenario. Green energy policy favours renewable energy sources, which can be seen in the smaller volumes of transported oil in the 2030 scenarios compared to the 2020 scenarios. In the Slow development 2020 scenario, oil transport volumes for 2020 are expected to be 170.6 Mt (million tonnes), in the Average development 2020 187.1 Mt and in the Strong development 2020 201.5 Mt. The corresponding oil volumes for the 2030 scenarios were 165 Mt for the Stagnating development 2030 scenario, 177.5 Mt for the Towards a greener society 2030 scenario and 169.5 Mt in the Decarbonising society 2030 scenario.
