Special Issue Information

Dear Colleagues,

Stringent environmental regulations, the volatility of fuel prices, alternative fuels, the development of emerging technologies, artificial intelligence methods, big data analytics, advances on ship systems autonomy/automation, and fourth industrial revolution concepts provide ship energy system designers and operators with both challenges and opportunities, which, if appropriately addressed, will result in step changes in the way the ships energy systems are perceived today.

This Special Issue provides a platform for academics, scientists and professionals from the industry to exchange the most contemporary ideas, techniques, methods and experience in the area of ship energy systems including modelling, optimisation, control, maintenance, safety, autonomy/automation, environmental friendliness, regulatory framework and sustainability.

This Special Issue mainly intends to accommodate studies and papers presented in the 2nd International Conference on Modelling and Optimisation of Ship Energy Systems (MOSES2019) held in the period 8–10 May 2019 in Glasgow, Scotland, UK. However, taking into account the importance and impact of topics as well as the variety of academic and industial groups working worldwide in the discipline of the ship energy systems, we invite all interested authors to submit novel/original studies and reviews that advance the scientific/technical understanding of the addressed topics.

A Comparative Analysis of EEDI Versus Lifetime CO2 Emissions

The Energy Efficiency Design Index (EEDI) was introduced as a regulatory tool employed at the ship design phase to reduce the carbon dioxide (CO2) emissions and increase the vessel’s operational efficiency. Although it stimulated the greening of the shipping operations, its effectiveness is considerably criticised from various shipping industry stakeholders. The aim of this study is to investigate the EEDI effectiveness on accurately representing the environmental performance of the next-generation ships power plants for two representative ship types, in specific, an ocean-going tanker and a cruise ship. The performance of the optimal power plant solutions identified in previous studies is analysed according to the existing EEDI regulatory framework and compared with the lifetime CO2 emissions estimated based on an actual operating profile for each ship. The results indicate that the EEDI underestimates the effect of technologies for reducing carbon emissions in all the investigated cases. In this respect, it is concluded that EEDI is classified as a conservative metric, which however can be used as an approximation to compare alternative solutions early in the design phase.

The selection of a proper machinery system is one of the primary decisions to be taken during the ship design phase. Nonetheless, this selection is made challenging by the presence of a variety of alternatives, and by the limited data availability at the early stages of the design phase. An optimization framework is presented in this paper, supporting decision making at the earliest stages of the ship design process. The framework is suitable to perform the screening and the selection of optimal machinery configurations for a predefined ship operational profile, and it includes both linear and non-linear optimization routines. The results of the linear and the non-linear approaches are compared, and indications on what conditions are the most suitable for the application of one or the other approach are provided. Both approaches are tested for two case studies, a bulk carrier and a small cruise ship. The results indicate that both optimization approaches lead to the same layout of the machinery system, but to slightly different unit scheduling. This suggests that the use of the linear approach is suitable for design purposes, but less appropriate for operational optimization. In addition, the findings of the work suggest that the trade-off between fuel consumption and volume of the engines should be considered when selecting the machinery system for a ship. Full article

Liquified natural gas (LNG) fuel has received significant attention as an affordable and highly efficient fuel option due to strengthened regulations on the sulfur content of bunker oil put in place by the International Maritime Organization. The main component of the LNG fuel gas supply system (FGSS) is the heat exchanger that provides adequate gas temperatures and pressures required by the engine, which also has a large machinery volume compared with other equipment. Due to the volume limitation, most FGSS have been applied to new shipbuilding only. To reduce the volume of the FGSS, CO2 was considered to serve as the replacement heat medium for conventionally used glycol water during LNG gasification. The specific power consumption (SPC) in the CO2 and glycol water system was optimized using the Aspen HYSYS thermodynamic modeler toward adjusting the temperature and pressure, and the resulting sizes were compared. This study demonstrated that the CO2 heat medium resulted in a 14% improvement in efficiency and a 7% reduction in heat exchanger size concluding that it was the most advantageous heat medium for the LNG regasification.
