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.

Naval vessels are routinely required to operate for long periods of time away from homeports. To sustain these deployments RAS (replenishment at sea) is a vital part of ship operations. A replenishment scenario typically consists of a receiving ship coming within range of a supply ship travelling at moderate speed. Transfer of fuel or supplies is then accomplished using a transfer rig running between the two ships. Among the various challenges during underway replenishment it is important to minimise the variation of distance between replenishment points on the two ships. Excessive variation of this distance can lead to undesirable events such as dipping of payload into water or breaking of transfer cables. A numerical analysis method has been developed to predict the motions of two ships during RAS operations. The simulation of these wave-induced ship motions and their influence on the distance between replenishment points of two ships at sea is described. Hydrodynamic interaction forces between the ships are modelled and their influence on the replenishment distance is examined. Representative results are presented for a naval supply vessel replenishing a naval frigate. Results from this type of study can facilitate assessment of the operational capabilities of the entire RAS system. Valuable information can also be obtained for use in defining training scenarios for ships crews and operational procedures for the replenishment of both existing and future naval vessels.
