Plus, a new method to predict ship resistance based on the evaluation of modern ship hull design will be detailed. The emphasis of the this book is on design for operational economy.

The material is directly usable not only in practice, in the design office and by shipowners, but also by students at both undergraduate and postgraduate levels. Table of Contents Main dimensions and main ratios: The ship's length; Ship's width and stability; Depth, draught and freeboard; Block coefficient and prismatic coefficient; Midship section area coefficient midship section design; Waterplane area coefficient; The design equation.

A certain degree of automation could cut costs spent on crew. But large companies are also, of course, looking for ways of maximising their profits. Another option would be ships that transport cargo around ports or along coastlines.

In fact, one firm already working with others to test and deploy fully autonomous vessels that do this sort of thing without human pilots is Kongsberg, of Norway. The Birkeland, an metre long ft container transporter will also be fully electric and is planned to enter service in the second half of Peter Due, director of autonomy at Kongsberg, extols the accuracy of the sensors on board its test vehicles. Machine learning trains the system to know what sort of objects are important to avoid, he adds. A recent report by the University of Southampton suggested autonomous ships will arrive faster than expected , because of falling technological costs and a demand to solve a labour shortage in some areas of shipping.

But as Due points out, bodies like the International Maritime Organisation IMO will probably take several years to design regulations that allow autonomous vessels to operate in international waters.

The Yara Birkeland, set to be completed next year, is claimed to be the first autonomous shipping vessel in the world Credit: Yara International. It is possible, for example, to build ships out of composite materials, for example glass fibres and plastic, which could greatly reduce the weight of some vessels and thereby improve fuel consumption and increase cargo capacity.

    The European Union recently launched a project — Fibreship — to develop composite material hulls for cargo ships more than 50 metres ft in length.
