Electrical plants onboard modern cruise ships and offshore rigs have nowadays reached a size and complexity comparable or even superior to big industrial plants and power plants. The continuous increase of the size of ships and the generally accepted adoption of electrical propulsion has led to the installation of MV power generation and distribution plants of very high power, tens of MW. Everybody who plans, manages or services these complex onboard power plants nowadays must have knowledge as well of HV plants and electrical machines, power converters, protection relays, of control and automation systems. This book intends to be an overview of technical features and planning issues of these electrical plants. It is meant to bear general validity, even if it is focused on larger ships with MV plants and electrical propulsion.
Electrical plants on-board modern cruise ships, offshore rigs and other naval vessels have nowadays reached a size and complexity comparable or even superior to big industrial plants and power plants. The continuous increase of the size of ships and the widely accepted adoption of electrical propulsion has led to the installation of HV (MV) power generation and distribution plants of very high power, tens of MW. Everybody who plans, manages or services these complex on-board power plants nowadays must have knowledge as well of HV plants and electrical machines, power converters, protection relays, of control and automation systems. This book intends to be an overview of technical features and planning issues of these electrical plants. It is meant to bear general validity, even if it is focused on larger ships with HV plants and electrical propulsion.
The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.

In 1974, a scientific conference covering marine automation group and large vessels issues was organized under the patronage of the Technical Naval Studies Centre (CETENA) and the Italian National Research Council (CNR). A later collaboration with the Marine Technical Association (ATENA) led to the renaming of the conference as NAV, extending the topics covered to the technical field previously covered by ATENA national conferences. The NAV conference is now held every 3 years, and attracts specialists from all over the world. This book presents the proceedings of NAV 2018, held in Trieste, Italy, in June 2018. The book contains 70 scientific papers, 35 technical papers and 16 reviews, and subjects covered include: comfort on board; conceptual and practical ship design; deep sea mining and marine robotics; protection of the environment; renewable marine energy; design and engineering of offshore vessels; digitalization, unmanned vehicles and cyber security; yacht and pleasure craft design and inland waterway vessels. With its comprehensive coverage of scientific and technical maritime issues, the book will be of interest to all those involved in this important industry.

This is volume 2 of a 2-volume set. Marine Design XIII collects the contributions to the 13th International Marine Design Conference (IMDC 2018, Espoo, Finland, 10-14 June 2018). The aim of this IMDC series of conferences is to promote all aspects of marine design as an engineering discipline. The focus is on key design challenges and opportunities in the area of current maritime technologies and markets, with special emphasis on: • Challenges in merging ship design and marine applications of experience-based industrial design • Digitalisation as technological enabler for stronger link between efficient design, operations and maintenance in future • Emerging technologies and their impact on future designs • Cruise ship and icebreaker designs including fleet compositions to meet new market demands To reflect on the conference focus, Marine Design XIII covers the following research topic series: •State of art ship design principles - education, design methodology, structural design, hydrodynamic design; •Cutting edge ship designs and operations - ship concept design, risk and safety, arctic design, autonomous ships; •Energy efficiency and propulsions - energy efficiency, hull form design, propulsion equipment design; •Wider marine designs and practices - navy ships, offshore and wind farms and production. Marine Design XIII contains 2 state-of-the-art reports on design methodologies and cruise ships design, and 4 keynote papers on new directions for vessel design practices and tools, digital maritime traffic, naval ship designs, and new tanker design for arctic. Marine Design XIII will be of interest to academics and professionals in maritime technologies and marine design.
The oceans are a key resource for transportation, energy and material extraction, and food production, representing one of the most important environments on the planet. Technological developments enabling us to exploit marine resources in a sustainable way are therefore of the greatest importance. This book presents the proceedings of the NAV 2022 conference, held in Genoa and La Spezia, Italy, from 15 to 17 June 2022. The conference is held every 3 years, attracting specialists in marine technology from all over the world. NAV 2022 was the 20th edition of the conference, and covered a full spectrum of maritime technology themes, all related to the exploitation of sea resources. The book contains 87 scientific papers, covering subjects ranging from comfort on board; to conceptual and practical ship design; deep sea mining and marine robotics; protection of the environment; renewable marine energy; design and engineering of offshore vessels; digitalization and cyber security; unmanned vehicles; yacht and pleasure craft design, and inland-waterway vessels. Providing a comprehensive coverage of the latest scientific and technical maritime issues, the book will be of interest to all those involved in this vital global industry.
