Although climate change is reducing the extent of sea ice extent in the polar region, it also enlarges the operation time window and enables more ships to choose routes where ice is prevalent. Global increases in maritime trade additionally factor into this. The number of polar ships is on the increase and the total exposure to sea ice is growing significantly. Ships sailing through ice-covered regions need to be powerful enough to overcome the additional resistance and strong enough to bear impact with ice. The methodology of designing polar ships, therefore, differs from that for open-water ships. This book is the first undergraduate and graduate textbook to introduce this topic, ideally for courses on polar ship technology or winter navigation. It sets out the formation process of sea ice, and its physical and mechanical properties, then describes the interaction process between ships and ice for estimating ice load. It introduces methods to evaluate ship performance in ice, including attainable speed and maneuverability, then establishes reliable polar ship rules, especially requirements for ice-strengthening. It sets out experimental methods, both model-scale and full-scale tests, and numerical simulation of ice loading and ship performance.

This is volume 1 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 demandsTo 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.
