Eleven chapters of the present book reflect the emphasis in the development and research of unmanned marine vehicles that was mainly made on the remotely operated and autonomous vehicles. The following two chapters are specifically addressing the underwater vision and its role in the unmanned marine vehicle navigation. The other four chapter deal mainly with the unmanned surface vehicles, while the closing chapter of the publication addresses the underwater gliders. Each of the chapters is some sort of self-contained exposition of the undertaker research work and some observations have also been provided. The motion equations developed for the UUVs have been provided in chapter two of the book, together with the various aspects of ocean currents. In the next chapter it is suggested that the a usual set of feedback controllers is there in the form of auto-pilot functions providing for the regulation of the speed, heading and depth/altitude of the vehicle. The fourth chapter is covering the technical guidance and control by means of a behavioral approach, while the fifth chapter presents a mixed approach for allocation of the thruster control or overactuated open framed remotely controlled vehicle...
Step into a full bathtub. You'll learn a lot about water. As your body sinks into the tub, the water moves out of the way. All around you, it rises. Now put a metal fork into the tub. It also pushes water away as it settles. But the amount is tiny. Still, you and the fork displace water for the same reason. Your weight pulls you clown. The force of gravity is doing it. Gravity pulls everything down on land, too. But there is more to the story. Water pushes up on objects that enter it. This upward force is called buoyancy...

The present Standard shall be considered the basic source reference of proper planning, safe handling and stowage, as well as securing and lashing of project cargoes. It is applicable to all vessels and forms a part of Rickmers-Linie QMS. Its declared purpose and spirit is to get the ship owners, stevedores and, in fact, any other involved parties informed about the safe cargo securing and handling techniques. All technical details of this Standard fully comply with the IMO Res. A.714(17), as amended. The document, in particular, is intended to provide detailed info on the lifting, bedding, securing and lashing of transported cargo and also deals with the equipment utilized; the maintenance related issues have also been addressed. The cargo information that must be supplied by the shippers as per SOLAS Chapter IV reg. 2, has also been described in this standard, together with the required configuration of bedding areas, securing points and lifting provisions. These aspects are to correspond with the tensile strength of the securing gear on board of the vessel as well as the deck layout. In case the requirements stated in this Standard cannot be met, an alternative solution providing the equivalent safety level is to be applied.
This book sets out the basic techniques for oxyacetylene welding, flame cutting, brazing, and electric arc welding with mild steel, stainless steel, cast iron, brass, copper, etc. in different forms (sheet/plate/cast).
This Guide was developed and released by the professionals of the Wallenius Wilhelmsen company, one of the world leaders in the field of the marine cargo transportation. The booklet is divided into three basic parts, namely Handling, Static Cargo, and Equipment. The Company carries huge volumes of static cargo all around the world, including machinery items, which require very careful hndling fue to the electronics fitted. The cargo to be transported is usually stowed on rolltrailers; however, the bolsters are also in use for the relatively small cargoes. In turn, bolsters and rolltrailers are secured to the ship's deck. The transporters must give due care and consideration to the details of cargo securing in order to avoid any possible mechanical stress since this can easily result in the damage to the cargo. Please note that this publication shall not be treated as the textbook; this is rather the booklet describing the company's experience and outlining some major static cargo transportation techniques. However, it will definitely be useful for people involved in marine transportation of cargoes since the techniques contained in it are worth having a look. It also addresses such issues as moving the cargo across land and sea, and bringing distances from shore to the sea
The full name of this document is Survey of Cargo Handling Research Relative to the MOB (Mobile Offshore Base) needs. Subject research was performs and results released by the National Institute of Standards and Technology (NIST). The MOB management team of the ONR (Office of Naval Research) considered crane development a critical technology required for any feasible mobile offshore base. Subsequently, they requested the NIST to asses the present-day state of practice in the field of crane automation as well as motion compensation. The present survey report is aimed to set a baseline and identify any further research required in order to satisfy the gaps in the technology, should any of the be revealed. The survey scope includes cranes and any other auto-technology utilized when performing the LO/LO transfer of cargo, including the containers. The authors made the emphasis on the containers transfer between the container vessels and mobile offshore bases. The issues related to the loading/unloading cargo brought by air are not dealt with in this report. the requirements applicable to the mobile offshore base cranes have mostly be developed in the NIST lab researches; however, some additional input was made by various developers of the MOB concept...

These guidelines were developed in 1998/99 for Exxon Chemical Europe Inc., Basic Chemicals Europe by Captain C. Allport of Standard Marine Services Limited and replace earlier guidance. They are based upon the report and advice from an LPG Measurement Survey conducted by Srini Sivaraman of ER&E in May/June 1997 and incorporate the earlier guidelines for Liquefied Gas Cargo Measurement and Calculation, produced in 1987 for Exxon Chemicals International by the Centre for Advanced Maritime Studies, Edinburgh. The earlier guidelines were adopted by Exxon Chemical International Inc. and approved by Regional Audit in 1988. The key to accurate cargo measurement based upon ship's figures depends on the precision of the tank calibration and calibration of associated level, temperature and pressure measuring devices in addition to the use of consistent methodology. Conformance to the recommendations made in these guidelines will result in transfer custody quality that is within the expectation of Exxon Corporation controls. The practices and procedures described in this document provide guidance for improving or maintaining liquefied gas measurement level of uncertainty within the accuracy requirements of Exxon's Hydrocarbon Measurement Practices (HMP) . Contrary to the general recommendations contained in the HMP, these practices and procedures will demonstrate that quantity determination can be based upon ship or barge measurement. Custody transfer integrity is comparable to and in some cases can be better than shore systems and match HMP requirements.

This ultimate goal of the authors of the present training manual was to provide the readers with the knowledge about how they should measure and calculate petroleum cargoes, how they should use the tools and instruments used on board their ships, and how they should understand and value the results obtained from instruments used on board. Finally, we would like to suggest some good and practical routines to be used on board your ship when measuring cargo. Nowadays, huge part of the world's oil reserves lies somewhere in and around the Persian Gulf. Those reserves are significant and will definitely last for a very long time. Huge amounts of crude oil will be produced and then transported by vessels from the oil producers to the industries. Usually, the oil companies seldom own their own tanker fleets. However, the petroleum products still have to be shipped and oil tankers will for sure continue to work on the high seas though today they are not actually run the traditional way and they are no more owned by the traditional owners. Most of the vessels are owned by shipping companies and their crews are usually employed by other, managing (in a restricted or "total" way), companies. Marine transportation of oil is a very complicated task...
This manual has been mainly intended to be used by the personnel concerned with the chemical testing as well as dosing and control of a shipboard water treatment. It includes technical explanations of why exactly the water treatment is always considered necessary and descriptions of various methods that are used in the modern marine practice. The book also explains the purpose and proper application of each chemical. Note that the present edition of the publication has been significantly updated in order to include the latest tests and treatments. Today, the power plants installed on board of the modern marine vessels are considerably more efficient than they used to be. The diesel engines and marine boilers are usually built with the main intention to get the maximum possible energy from the fuel and to turn subject energy into work. Moreover, the electrical generators and turbines plus all auxiliary equipment are designed to provide the max effective utilization of the mechanical or steam energy supplied to them. The effectiveness of the shipboard power plant operation would mainly be dependent on the quality of the received water. In the meantime it shall be taken into account that various contaminants could cause serious damage to the power plant equipment.
The main dimensions decide many of the ship's characteristics, e.g. stability, hold capacity, power requirements, and even economic efficiency. Therefore determining the main dimensions and ratios forms a particularly important phase in the overall design. The length, width, draught, depth, freeboard, and block coefficient should be determined first. The dimensions of a ship should be co-ordinated such that the ship satisfies the design conditions. However, the ship should not be larger than necessary. The characteristics desired by the shipping company can usually be achieved with various combinations of dimensions. This choice allows an economic optimum to be obtained whilst meeting company requirements...
The intent of this GMDSS Handbook is to provide a thorough and detailed explanation of the principles upon which this system is based, the operational performance standards as well as the method of operations/procedures for the huge number of radio services which form the Global Maritime Distress Safety System, including the Master Plan, in a single and very comprehensive publication.
As the industry professionals, we are for sure aware of the fact that the number of substandard vessels significantly increased in the period 1980-1990. This was seen by all governments as a serious threat to the life at sea as well as to the marine environment. As a result, most of the IMO members came to the right decision to use even greater efforts in order to ensure due compliance with the regulations developed by the IMO making a good attempt to reduce the number of such substandard vessels. DNV, one of the world's leaders in providing classification services, developed the present Guide which can be used as a very informative and useful tool by ship masters, crew members and officers both ashore and on board to achieve required compliance with the requirements covering the safety of life at sea and protection of the environment - it is actually an invaluable instrument for preparation for the PSC inspection. It may be treated as a good supplement to the maintenance system established on the ship, and will direct people on board to better focus on the maintenance of the critical areas that are usually in focus of PSC. By doing so, they shall be able to better prepare their ship for the forthcoming visit of the PSC inspector and avoid any problems.
This official NK Guidance was released to be of some use for the ship owners, operators, crew members and others dealing with preparation of the vessel for the classification surveys. As the mane implies, the publication addresses the ships classed with the NK Class Society and lists the requirements of this Society, accordingly. It will provide the point on the major survey items and all related class requirements together with the instructions on preparations that are necessary to be made in order to successfully pass alll such surveys - the documentation aspects have also been covered. The publication will also help the survey applicants, i.e. the vessel owners or their reps to carry out the surveys mentioned above fast and economically as scheduled. Of course, for details you would better refer to the applicable Rules and Guidance issued by NK. The Guidance consists of several major chapters addressing the survey application and preparation aspects, arrangement of the surveyor's attendance, maintenance of documentation and its presentation, actual items to be surveyed, ESP (enhanced survey program), requirements applicable to the general dry cargo vessels, assessment of the coating condition of the ballast tanks, repairs etc.
The aim of the book is essentially the same as that of the prior editions; namely, a textbook "to assist students and others entering the field of shipbuilding towards a knowledge of how merchant ships are designed and constructed and to provide them with a good background for further study." Nevertheless, a number of considerations led the Committee to modify extensively the scope and organization of the book. At the outset, the Committee recognized that within a few years the Society's book Principles of Naval Architecture would also be revised and that it contained material which more properly pertained to design and construction rather than theoretical naval architecture. Therefore it recommended, and the Publications Committee as well as the Executive Committee approved, the inclusion in Ship Design and Construction of new chapters on Load Lines, Tonnage, and Launching which would then be deleted from future editions of Principles of Naval Architecture. As a partial trade-off toward page reduction, the Committee eliminated the 1969 edition chapter on Submersibles because of its relatively narrow field of interest and the lack of major new developments for commercial operations.
The ultimate aim of this updated and thoroughly revised edition of the book was to provide readers with the practical technical information directly related to the marine boilers and associated equipment used at sea on board steam and motor vessels. There are so many typical examination questions included in the guidebook together with the correct answers as well as clear explanations to help readers in their qualification as marine engineers. The publication also contains some valuable information on marine boilers of welded construction and various types of water-type marine boilers, supplemented with the useful and informative instructions on how exactly to deal with rotary air heaters, water level alarms and safety valves of consolidated type; moreover, the book contains some valuable notes relating to the hydraulic testing and covers various aspects of the inspection, periodic maintenance of the main types of marine boilers and possible operational problems that could be faced by the personnel. It is a truly excellent reference volume for the students and a good guidance for the experienced professionals willing to refresh their theoretical knowledge of the construction and operation of the marine boilers, that is why we can recommend it to all categories of people dealing with the marine boilers.
Another book by Peter Goodwin, one of the world respected and recognized experts and writers on the sailing warships of the past. The publication keeps the brilliant tradition of the series. The research performed by the author is perfect and thorough, covering all stages of the development as well as remarkable service life of the vessel. The ship modelers will definitely appreciate the efforts made by the author as they are getting the invaluable source of detailed technical info and images aimed to make the process of building the model of Granado much easier and smooth. Apart from the model makers, the publication will be very good for anyone willing to learn something new on this warships and on the general construction of the old-time warships. The book features many first-class photographs taken a model exposed in the National Maritime Museum. The line drawing details are very informative and comprehensive. We were really impressed with the attention paid by the author to the details, such as masts, various rigging, sails, planking etc. This book is a genuine dream for the ship model maker - moreover, historians will also find it nice due to the historical background and measurements provided for this old and classic ship.
The Anatomy of the Ship book dedicated to the eternally famous armed transport Bounty. Centuries ago, in the year 1775, The Standing Committee of West India Planters & Merchants decided to introduce bread-fruit trees and mangosteen into the West India colonies as an inexpensive source of food for their plantation slaves. An excellent prize was offered to anyone who successfully transported bread-fruits from the East to the West Indies, and, in 1777, a fund was set up to encourage people's interest in the subject adventurous and so interesting project. The book starts with the introductory chapter providing some historical background. Then, there is info on the hull construction, refit and decoration, steering gear and ground tackle, pumps, boats, crew and accommodation, masts and yards (with dimensions specified), sails, rigging, ordnance. This chapter is followed by a number of nice close-up photos of the full size replicas of the HMS Bounty, and the next and last section of the publication contains and a truly huge collection of detailed technical drawings, including three-view drawings, and good construction plans. we do believe it is needless to say that the full and thorough description of the vessel is also provided to the reader.
The battle of the Atlantic pitted Germany's U-boats against Allied convoys sailing from North America and the South Atlantic. The name itself is a bit of a misnomer as it was not one single battle but the longest continuous military campaign of World War II, lasting for six years, stretching over hundreds of miles and involving almost countless combat engagements. By the end of hostilities, the Kriegsmarines U-boats had sunk in excess of 2,900 ships, representing over 12 million tons of Allied shipping. Despite some post-war claims that the U-boat campaign had no real chance of being successful in the long run, it is clear that the Allied leaders at the time had a different view. By January 1943. such were the worries over the U-boat's successes that at the Casablanca conference, it was agreed that the defeat of the U-boats was to be a number one priority. Indeed, when summarizing his thoughts on the Battle or the Atlantic, Prime Minister Winston Churchill famously said, 'The only thing that ever really frightened me during the war was the U-boat peril'. The Battle of the Atlantic was not only a fight for the survival of Great Britain, but for the survival of real opposition to Hitler. If the U-boat campaign had succeeded and Britain had been starved into subjugation, the British Isles wouldn't have served as a base for the eventual bombing offensive and as a launching point for the invasion of Kurope. It is difficult to envisage how the stakes could have been higher...
