INTACT STABILITY

by Colin S. Moore, Edited by J. Randolph Paulling (2010)

Written by Dr. Colin S. Moore, Manager, Advanced Analysis and Salvage Engineering at Herbert Engineering Corp. and a member of SNAME ad hoc committees on Double Hull Intact Stability and Parametric Rolling, the new volume in the PNA series discusses various effects on stability, such as changes in hull geometry, changes in weight distribution, suspended weights, partial support due to grounding or drydocking and free liquid surfaces in tanks or other internal spaces.

The concept of dynamic stability is introduced, starting from the ship’s response to an impulsive heeling moment. The effects of waves on resistance to capsize are discussed noting that, in some cases, the wave effect may result in diminished stability and dangerous dynamic effects.

PROPULSION

by Justin E. Kerwin and Jacques B. Hadler, Edited by J. Randolph Paulling (2010)

This book presents a comprehensive and up-to-date treatment of propeller analysis and design, including beginning with an introduction to various types of marine propulsion machinery, definitions of powers and efficiencies, and two- and three-dimensional airfoil theory. A section on three-dimensional hydrofoil theory introduces wake vortex sheets and three-dimensional vortex lines. These discussions topics are followed by linear lifting line- and lifting surface theory with both exact and approximate solution methods—including properties of helicoidal vortex sheets, optimum and arbitrary circulation distributions, and the Lerbs induction factor method. There are sections on model testing of propellers, propeller strength and followed by selection and design using both standard series charts and by circulation theory. The final section discusses ship standardization trials, their purpose, measurement methods and instruments, concluding with the analysis of trial data and derivation of the model-ship correlation allowance.

SHIP RESISTANCE & FLOW

by Lars Larsson & Hoyte C. Raven, Edited by J. Randolph Paulling (2010)

The Principles of Naval Architecture series is the defining reference work and text for naval architecture. This volume contains a completely new presentation of the subject of ship resistance embodying these developments. A major goal in the design of virtually all vessels is to obtain a hull form having low resistance. In achieving this goal, the accurate prediction of resistance for a given hull geometry is essential. Since the publication of the previous edition of PNA important advances have been made in theoretical and computational fluid dynamics accompanied by increased use of such work in ship and offshore structure design. 

The first section of the book provides basic understanding of the flow phenomena that underlie the resistance encountered by a ship moving in water. The second section contains an introduction to the methods by which that knowledge is applied to the prediction of resistance, including model testing, empirical methods and computational methods. A final section provides guidance to the naval architect in designing a hull form. Design procedures are described for achieving favorable flow and resistance characteristics of the hull and appendages. Examples are given for ships designed for high, medium and low speeds. Design considerations affecting both wave and viscous effects are included. Finally the flow in the stern wake is discussed, an area important for both resistance and propeller performance.

STRENGTH OF SHIPS AND OCEAN STRUCTURES

by Alaa Mansour and Don Liu, Edited by J. Randolph Paulling (2008)

This new revised volume on Strength of Ships and Ocean Structures addresses several topics of ship strength in greater depth than in the previous edition of PNA, bringing much of the material up to date and introducing some new subjects. There is extensive coverage of the latest developments in dynamic sea load predictions, including nonlinear load effects, slamming and impact plus new sections on the mechanics of collisions and grounding. The incorporation of the various loadings in structural design and analysis is covered including long term extreme and cumulative fatigue effects. There is a more extensive treatment of strength analysis using finite element methods than was included in the previous edition. Ultimate strength evaluation of the hull girder and components is covered and there is a section on structural safety assessment applying reliability concepts including fatigue effects. Particular attention is given to problems encountered in ships of special type and size that have been developed in recent years, many of which, by reason of size, configuration or lack of a history of design experience, require a design approach based on first principles. Modern developments in classification society strength standards and modern rule developments are covered including Common Structural Rules for tankers and bulk carriers. The concluding sections discuss materials other than steel, including composites and aluminum, and vessels of unusual geometry and performance such as multihulls, hydrofoils, and SWATH craft.

VIBRATION

by William S. Vorus, Edited by J. Randolph Paulling (2010)

Principles of Naval Architecture series is the defining reference work and text for naval architecture. This volume presents the principles underlying analysis of the vibration characteristics of modern seagoing ships and the application of those principles in design and problem solving. 

The classical continuous beam model with steady state response to periodic excitation is presented first. This includes natural frequencies, mode shapes and modal expansion. Discrete analysis is next presented based upon finite element principles. Examples are discussed involving analysis of the entire ship and component parts, e.g., the deckhouse. There are sections on vibration surveys, sea trials, acceptable vibration standards and criteria. Concluding sections treat methods of remediation of vibration problems that are found after the ship is completed, including modifications to propeller design, structure and machinery.
