Continuous training is considered nowadays as a key issue for the evolution of people being at professional and personal levels, enhancing productivity, employability, and social stability in a globally competitive world. Furthermore, the introduction of new technologies, the imposition of new regulations in the maritime industry and the growing challenges at port, shipping and logistics level increase the demand for new educational schemes. Concerning the market needs, TrainMoS II and On the MoSway Network (OTMW-N) European projects aimed for the development of student and professional's skills and laid the foundations for a cross-European maritime educational programme. TrainMoS II was the evolution of the TrainMoS project, improving the existing tools and covering a whole new range of technical and operational topics, including alternative fuels and technologies, logistics and safety issues such as damage control, evacuation and crisis management operations. TrainMoS II covered also the provision of blended vocational education to undergraduates and professionals who belong to different sectors in the multimodal transport chain. Both projects focused on the establishment of an educational framework facilitating the collaboration between industry and academia and used advanced ICT tools to match the maritime market needs with the training provision and to develop new and enriched content for the online platform with learning material and knowledge for both professionals and students. In the present study, the outcomes and experiences gathered from running the aforementioned projects are presented and discussed for their potential impact on the maritime industry.
Ship acceleration manoeuvre is important in terms of safety and engine performance. Head seaways are one of the most challenging conditions for the ship propulsion. A detailed simulation of the propulsion system’s transient response during dynamic acceleration in harsh conditions can result in a thorough investigation of the engine performance, a better management of control system and the monitoring of engine limiters application in real conditions. For the overall propulsion system performance assessment during ship acceleration, a computational tool has been developed that comprises sub-systems for the simulation of engine, turbocharger, propeller components and their interaction. The developed tool has been validated against available shop and sea trials data and then it has been tested for the simulation of propulsion system performance during acceleration in dynamic conditions. Based on the simulations results, a sensitivity analysis has been performed for the investigation of the governor control unit limiters that apply on the engine during acceleration. As a result, the effect of engine governor limiters on the overall engine and hydrodynamic performance of the ship during acceleration is quantified and discussed
The matching of the turbocharging system with a marine engine is an essential undertaking due to the turbocharger effects on the engine performance, emissions and response, whilst the limited data availability during the ship design phase renders it challenging. This study aims at developing a novel methodology for the matching of a single turbocharger and multiple turbochargers connected in parallel with marine engines. This methodology employs a compressor parametric modelling tool and a zero-dimensional engine model, whilst taking into account the engine operational profile and the turbocharger components flow limitations. The compressor parametric tool is used for the generation of a database with compressor families that can be investigated during the matching procedure. The model of one engine cylinder block is used for mapping the engine performance parameters at a wide engine operating envelope by developing response surfaces. The developed methodology is implemented for the case study of the turbocharger matching with the propulsion engine of an Aframax tanker. The annual fuel consumption and the engine load diagram upper limit are employed as the main objectives for the selection the turbocharging system. The derived results demonstrate that the effective turbocharger matching results in reducing the engine brake specific fuel consumption up to 5%. The identified turbochargers led to the reduction of the ship annual fuel consumption in the range 1.3%–5.3% compared to the reference engine, whilst providing a more expanded load diagram. This study overcomes the limitations of the manual engine turbocharger–matching process providing decision support on the effective turbocharger matching to satisfy contradictory objectives.
