Powered Watertight Doors

   Powered watertight doors are extremely heavy and powerful: incorrectly used, they can maim and kill. Everyone on board must clearly understand all risks associated with powered watertight doors and how to operate them safely. Sliding powered watertight doors are fitted in bulkheads on passenger ships, RO-ROs and other types of vessel. Their purpose is to enable ship personnel to move from compartment to compartment, and, in the event of flooding, to prevent water spreading through the ship, for example, if the hull should be breached during a collision or grounding, or if there should be a structural failure. Ships' hulls are divided up into watertight compartments. If water should come in, the closed powered watertight doors will contain it in the compartment where the damage occurred. On certain Types of vessel, the accommodation and machinery spaces may be spread out horizontally across the length of the hull and therefore across a number of watertight compartments. People need to be able to move horizontally along each deck from space to space, but any flood water must be restricted to the smallest possible area. Powered watertight doors therefore function as a moveable section of the bulkhead that allows access between the compartments. You may use this training video with the booklet.

Guidebook for the Design of ASME Section VIII Pressure Vessels

   The ASME Boiler and Pressure Vessel Code, Section VIII, gives rules that pertain to the design, materials selection, fabrication, inspection, and testing of pressure vessels and their components. With few exceptions, the rules that cover the design of components tend to be complicated to implement. This book was written to demonstrate the application of the design rules to various components. Other rules, such as those pertaining to fabrication, inspection, testing, and materials are not covered here. This book is intended as a reference for designers of pressure vessels and heat exchangers. The theoretical background of the equations used here was kept to a minimum, since such background can be obtained from other references. Note also that while the design requirements of such components as shells and heads are interspersed throughout the ASME Code, design requirements pertaining to some specific components are given here in one chapter for easy reference. The emphasis in this book is on solved examples, which illustrate the application of the various equations given in the ASME Section VIII Code. Chapter 1 of this book covers background information and general topics—such as allowable stresses and joint efficiencies—applicable to all components. Chapter 2 is for the design of cylindrical shells under internal and external loads. Chapter 3 covers the design of dished heads and transition sections that are under internal and external loads. Chapter 4 considers flat plates, covers, and flanges. Openings are reviewed in Chapter 5, and Chapter 6 covers special components of VIII-1, such as stayed construction, jacketed components, half-pipe jackets, and noncircular vessels. Chapter 7 covers heat exchangers, and Chapter 8 covers stress categories, fatigue, and other special analysis of components...

Testing and Balancing HVAC Air and Water Systems

   Some intro from author... This book is based on my field and teaching experience in testing, balancing, designing and evaluating HVAC systems. There are two basic methods of balancing. One method is balancing from the terminals back to the fan or pump. This method is proportional balancing. It was during a job at a nuclear power plant many years ago that I first started using the proportional method that I have outlined in this text. As we could not get enough experienced balancing technicians for the project, I began instructing sheet metal mechanics with little or no balancing background in proportional balancing. I found that the proportional method was quickly learned in a classroom setting and then applied to the field. The proportional method follows a scientific approach with quite predictable results, it also establishes a starting point and allows others with proportional balancing experience to take over the balancing when there is a need for that, large systems are balanced quicker, and the least resistance is imposed on the system while delivering air or water to the terminals at design or at the highest possible flow quantities... The author has continued to teach the presented method in his classes, seminars and in-house training programs and now with the СТАВ program with great success...

Machinery Condition Monitoring Principles and Practices

   While teaching the subject of machinery fault diagnostics and signal processing, and conducting short courses for industry professionals for more than fifteen years to the senior year and graduate students at the Indian Institute of Technology, Kharagpur, I have always had a problem locating a single book on the subject. Though there are excellent research journals and trade magazines on the subject, I have failed to locate a book without bias toward the equipment used or process followed for detecting faults in machines in general, and rotating machines in particular. With this preamble I began to write this book, drawing on my experience with machinery condition monitoring while consulting for many industries in India and abroad over the last two decades. In many of my fault-detection exercises in the industries where I have consulted, I have come across technicians and engineers who wonder what fast Fourier transform (FFT) is, and I have been provided with a table full of numbers and asked to find the fault in the machines. Many engineers in the field learn this subject from the technical brochure of the equipment they use, without understanding their limitations. They feel that since they have a piece of costly equipment at their disposal, they can detect and diagnose the fault in any machine. One of the purposes of this book is to eliminate such myths. No offense intended. There are many commercial software packages available in the market to do diagnostics, but with an understanding of the subject, an engineer can better appreciate the diagnostic routines, because garbage in is garbage out.

Two-Stroke Engine - Repair and Maintenance

   As two-strokes fire every revolution, they are the most powerful engines for their size known. Highly tuned examples develop nearly two hp per cubic inch of displacement and run happily at 11,000-plus rpm. And with only three basic moving parts, two-strokes are the simplest and least expensive form of internal combustion. Yet, for many owners these little engines are contrivances from hell, cantankerous, difficult to start, and impossible to fix. Drive by a suburban neighborhood on trash collection day and you will find edgers, weed trimmers, and Chinese mini-bikes awaiting pickup at the curbside. The very simplicity of the two-stroke principle makes it unforgiving. Actually, these engines are easy to live with, if you have the background information and the tools to make a few simple diagnostic tests. And once past the fear of getting their hands dirty, most people find that fixing things is rewarding. Certainly it is more rewarding than spending $85 an hour (the current big-city shop rate) for someone else to do the work. Nor can we continue to discard products that no longer function as they should. That phase of American experience is behind us...

Fitness-for-Service and Integrity of Piping, Vessels, and Tanks

   This book is an exploration of failure in tanks, vessels, and pipes. This is done from an engineer's perspective, which means that it has to be usable to make run-or-repair decisions, to decide whether the component is still "fit for service," or whether it should be repaired or replaced. Fitness-for-service is the understanding of why, when, and how tanks vessels, and pipes fail. The answer is at the crossroads of mechanical design and analysis, metallurgy, welding, corrosion, inspection, and a good grasp of operations. These disciplines have to merge into a succinct and clear answer, preferably a single number: how much longer can the component operate safely. In answering this question, the engineer will have to rely on experience and science, and will have to reach a quantitative answer in the form of time to failure or margin to failure. This book is a modest addition to the many documents that address the interesting question of fitness-for-service. Foremost among publications dealing with the topic is the American Petroleum Institute's Recommended Practice API 579 Fitness for Service, a document which through its elegance, completeness, and practical value remains unmatched. The reader is urged to apply the API practice and other codes and standards referenced in the text, as they are the authoritative references to be used in making fitness-for-service and run-or-repair decisions.

Rudder Propeller and Hull Interaction by RANS

   In ail attempt to increase the safety at sea more attention has been focused on the requirements of the education of the officers sailing the ships and of the maneuverability of the sliips. Tliis has of course increased the interest in the numerical maneuvering simulators, which are a strong tool for investigation of the maneuverability of the ship and for the training of the crew members. Consequently, the increased interest lias resulted in stronger requirements of the quality, accuracy and reliability of the maneuvering models behind the simulators. The simulators are doing well today, but there are still areas where additional knowledge could be useful to improve the models. One of these areas is the interaction between the rudder, propeller and hull, which plays an important role for successful modeling of the maneuvering problem. Today the state of the art in maneuvering simulation covers the full mission simulators based on numerical solution of the equations of motion in conjunction with experimental hydrodynamic data which is mainly determined by means of captive model testing techniques like the planar motion mechanism (PMM). A study of the maneuvering model and the PMM model testing technique applied to the data generation revealed that a comprehensive set of experimental input data was required in order to perform a maneuvering simulation and model the rudder, propeller and hull interaction.
