Emerging Developments and Global Challenges

Marine transportation is considered as an integral part of the global economy as more than 90 per cent of global trade goods are carried through the sea. The shipping industry underwent a tremendous growth during the last century (from 2.6 billion tons annual shipments in 1970 to 9.2 billion tons annual shipments in 2012). The International Maritime Organization (IMO) has been vigorously seeking for new measures for further improvements in energy efficiency and emissions reduction, and swift implementation of these measures to reduce the harmful emissions from international shipping. Chapter One provides the basic formulation of a coupled finite element of interface. It is followed by two examples of applications related to the vertical (uplift) or lateral loading of a suction caisson. In Chapter Two, the authors try to introduce some examples of propulsion layouts related to their previous experience introducing simplified criteria for a global design of the propulsion layout. This is achieved by melting mechatronics, fluid dynamics and more generally miscellaneous engineering topics that are often deeply studied by different working teams with different competences. In Chapter Three, a comprehensive overview of green ship technologies is presented which includes basic concepts, principles and potential, related core issues and possible solutions.
