The possibilities of energy cost savings in the field of shipboard power generation are discussed. One way of achieving these is by the conversion of diesel generators to heavy fuel operation since such oil is cheaper than marine fuel oil. But with regard to reliability and long-term savings the use of shaft-driven generators particularly on ships with fixed-pitch propellers and slow-running 2-stroke engines is much more promising. Such systems have been proven in practice for 15 years and their continuing development is described. Latest developments include combined supply systems incorporating the various alternatives of power take-off from the propeller shaft and using one-fuel ships.

First edition “The purpose of this handbook is to assist shipowners, shipbuilders, marine superintendents, dock authorities, underwriters, ships’ officers and others, to understand a very difficult subject. It deals with the regulations actually in force, and the author has done his best to present the same in a clear and helpful manner, free from confusing technicalities, which, it is hoped, will enable the reader to obtain an intelligent insight into the important essentials which have a direct bearing on the successful operation of ships in their relation to the measurement for register tonnage.”

The methodology to estimate ship emissions developed within the project Methodologies for estimating air pollutant emissions from transport (MEET) funded by the European Commission is considered. The development of a simplified methodology to estimate consumption and emissions based on current statistics of ship traffic is looked at. The development of a detailed methodology compiled using an organic fuel consumption database for ships on a ship by ship basis and the use of appropriate emission factors is discussed.

Problems and aspects of ship/machinery design peculiar to ice-capable and ice-breaking ships are discussed including - machinery cooling systems; propulsion shafting (gears shaft bearings thrust bearings stern tubes); propellers (fixed and controllable pitch); bow thrusters; steering gears; chocks (machinery collision); air bubbles; pollution control systems (oil sewage).

In the marine industry some far reaching and demanding international legislation to control air pollution from ships is being evolved. Proposals have been put forward within the International Maritime Organisation (IMO) to lessen sulphur oxide (SOx) emissions from ships by reducing the sulphur content limit of marine bunker fuel. While information is still limited concerning the relationship between ship emissions and their real contribution to damaging effects data is becoming available to help direct future investment by the oil industry to ensure meeting the product quality requirements of the bunker market.

This book presents painting methods for the protection of steel ships and structures against corrosion. It includes the formulation of suitable paints as it requires a knowledge of the mechanism of corrosion under various conditions and of the mechanisms by which paints prevent corrosion. Contents include: Introduction; Surface Preparation; Blast Primers (Prefabrication primers); Ships’ paints; Paints for Structural Steel.

A theoretical study examines seakeeping in head seas for hull forms from the extended Series 60 cruiser-stern ships. Mathematical methods are described and some experimental verification included. The results are presented as extensive Seakeeping Tables in which heave pitch bend added resistance acceleration relative motion and relative velocity are given as functions of principal characteristics. Further discussion includes use of the Tables to predict the seakeeping behaviour of non-Series 60 cruiser stern ships and to obtain more extensive seakeeping information such as wetness Keel emergence slamming and propeller racing.

Contents include chapters on the following: conditions of ship propulsion, theory of screw action, model screw propeller experiments, propellers in open water, single-screw ships, twin screws behind ships, multiple screws, shallow-draft river steamers, cavitation and propeller failure and steam trials and log analysis.

The contents of the book are arranged in two parts. The first part deals with 'The sea and ships', looking at: seaworthiness, ship types, the ship girder and structural details and statutory regulations. The second part, 'Naval architecture', looks at: stability, trim, watertight subdivision, strength and vibration of ships, rudders, resistance and powering and propulsion and propellers.

An on-going study into the use of fast ships in commercial transportation operations using the total cost concept is outlined. Economic assessment of recently built or designed large fast passenger and car ferries are discussed including a parametric study using transport factor analysis and a total transport cost analysis of various modes of transport. The use of fast ships for transporting commercial freight is also discussed.

A new concept in ship design and operation is required if the predicted manpower shortages in shipping are to be overcome and further cost reductions achieved. Unmanned ships have been proposed as a possible solution overcoming the manpower problems and in this paper the results of a technical and economic appraisal of a fully automated unmanned cargo ship are presented within the context of expected world developments in the next decades.

Problems caused by moisture in ships' cargo holds briefly discussed and basic principles of a dehumidification system outlined. Experience with installations on freighters and cargo ships illustrates development of the equipment for full scale and portable units.

Results are presented of the study of the possibility of safe handling of directionally unstable ships. Several pilots were asked to manoeuvre directionally unstable models with different amounts of instability and an attempt was made to establish allowable limit of directional instability of ships on the basis of the analysis of these tests. The results are compared with a similar study conducted in Japan.

Results of full scale steering tests made on the in-service cargo ships Dolius (twin screw steam) City of Lyons (single screw steam) and Highland Monarch (twin screw motor) are compared with those made on scale models of the ships (free and constained) at the William Froude Laboratory.

In this paper the longitudinal strength of ships in rough seas is investigated with reference to slamming. Besides the calculations a series of tank tests are conducted in a basin making use of an elastic model ship. Special interest is concentrated on the occurance of serious bottom slamming for full-bodied ships in fully laden conditions.

The role of risk assessment is considered in the decision- making process for providing a safe haven for ships in distress. This paper comprises a short half-page abstract followed by some 21 pages of conference overhead projection sheets.

The use of aluminium sandwiched panels in the construction of fast ships is described. Their use is effective in attaining a light construction of ship hulls. The panels are brazed aluminium honeycomb and extruded hollow section panels. The application of the panels to experimental ships sailing in real waterways is described.
