It is universally recognised and accepted that overall ship vibration as an important measure to ensure the habitability, safety and functionality of marine vessels. This book examines the causes and effects of ship vibration to provide users with specific guidance on the design, analysis, measurement procedures and criteria in order to achieve the goal of limiting the ship vibration to an acceptable level. This Book 1 considers the design and construction of the hull, superstructure, and deckhouse of a steel vessel based on all applicable requirements of established classification society (Class) rules. Specifically, for container carriers over 130 metres in length, the Class rules require the consideration of vibratory responses of hull structures, as applicable. For LNG carriers, the Class rules require special attention to the possible collapse of the tank membrane due to hull vibration. For ship-type floating production units with spread mooring, the rules relating to the building and classing of facilities for offshore installations require the flare tower/boom and hull natural frequencies to be separated to avoid resonance or near resonance. This book should be read in conjunction with Book 2, Propulsion Shaft Alignment, which considers the effect of propulsion shaft vibrations. This book provides practical guidelines on the concept design to assist ship designers to avoid excessive shipboard vibration at an early design stage. These guidelines also assist with the finite element analysis (FEA) based vibration analysis procedure to calculate the vibration response and evaluate the design at detail design stage. The analysis procedure represents the current analysis practice used by Class. These guidelines also offer guidelines on the vibration measurement procedure at sea trials and the acceptance criteria on vibration limits based on international maritime industry standards

Working and living onboard vessels imposes a series of generally low-frequency mechanical vibrations as well as single-impulse shock loads on the human body. Also, exposure to noise is characteristic aboard vessels. Low-frequency vibrations are created by vessel motions, which are produced by the various sea states in conjunction with vessel speed and point of sail. These motions can result in motion sickness, body instability, interruptions of task performance, sleep interruption and fatigue, increased health risk aggravated by shock loads due to slam and reduced human efficiency. Higher-frequency vibration influences comfort and is often associated with rotating machinery. The imposition of higher frequency vibrations (about 1 to 80 Hz) induces corresponding motions and forces within the human body creating discomfort and reduced human efficiency. With regard to noise, the above can similarly affect exposed humans, notably with sleep interruption and resulting fatigue, discomfort, and reduced efficiency. Also of concern are transient and permanent hearing loss, masking of audible signals, and interruption of speech communication. The concerns related to levels and characteristics of noise and vibration are covered in these two books which are related to habitability on ships and offshore structures. The purpose of this Book 2 is to provide clarification for Class Surveyors and plan review engineers to verify consistency of the survey and plan approval processes. Regarding the shaft alignment design and implementation efforts by the shipbuilding industry, this book is designed to further advance the technical approach towards shaft alignment analyses and procedures. The book is arranged to include topics on shaft alignment condition monitoring and a section dedicated to alignment problems and their solutions. Shaft alignment survey requirements are summarised in the introduction and are addressed further under a separate chapter on shaft alignment procedures and practices. Discussion on alignment calculation and measurement is expanded on to include the stern tube bearing clearance measurement. Additional clarification is provided on the application of the hull deflections, alignment optimisation, propulsion systems with no forward stern tube bearing, and reverse engineering calculations.

Ship designers in pursuit of these notations often request guidance on how to control levels of noise and vibration in inhabited spaces. As a result, this book has been written. The information presented in this book is intended for guidance only to support vessel designers and operators in controlling vessel noise and vibration in the general case, and more specifically in meeting the requirements of classification society habitability rules.

The book focused on the basic bottleneck issues in the ship uncertainty-based design optimization. Based on the concepts of robustness and reliability design, uncertainty classification, uncertainty modeling, uncertainty analysis and propagation methods were systematically explained, revealing the influence mechanism and rules of multi-source aleatory and epistemic uncertainty on ship design. Finally, a hull form design optimization method with mixed uncertainty was established. The theory of uncertainty design optimization is not yet mature, and this book gives a detailed introduction. The illustrations and tables in this book compared the differences between uncertainty-based optimization and traditional deterministic optimization, reflecting the advantages of uncertainty optimization. This book will be a useful reference for researchers and engineers in the field of ship design.

This book describes a slamming strength assessment procedure for vessels. Typically, there are three types of slamming loads on commercial vessels: bottom slamming, bow flare slamming, and stern slamming depending upon the hull geometry at the bow and stern. Upon verifying compliance with the requirements in this book, optional notations may be assigned to the vessel. A fundamental requirement of Class is that the scantlings of the hull structure are to be in accordance with the criteria as specified by Class. The results of this book are therefore not to be used to reduce the basic scantlings obtained from the application of the Class rules. That is, if the results from this book indicate the need to increase any basic scantlings, the increased scantlings are to be implemented above the Class Rule requirements.

This book combines and summarizes the myriad rules, regulations, guidance, and guidelines that pertain to the human factor element of vessel design and marine operations. With a focus on physical ergonomics, the book is thoroughly researched and draws on the most current Class rules and industry regulations promulgated by the IMO and other organizations. As such, this book serves as a single point of reference for professionals and students involved in human factors and ergonomics at sea.
