The modern shipping industry has reached maturity; market demand and landscape shifts force industry agents to find new pathways to successful development. The Northern Sea Route (NSR) as a new pathway between Europe and Asia brings both opportunities and challenges to global logistics systems. These circumstances make commercial exploitation of the route a subject of intense focus in many countries actively involved in sea transportation. This book identifies specific problems and provides possible solutions to them by calling on the accumulated knowledge of researchers and practitioners with competencies from diverse areas, including transport and logistics, Arctic studies, IT and digital technologies, socio-economic systems analysis, hydrocarbon production, transport, business modeling, design of information systems and applications, and engineering requirements for IT services. It represents the integrated experience and expertise of researchers from Canada, Germany, Russia, and the Netherlands, including experts from oil and gas enterprises, shipping lines, logistics companies, and IT companies.
