Available in PDF, EPUB and Kindle. Book excerpt: Vessels ftted with azimuthing podded propulsors have much better maneuvering capabilities. They are also environmentally friendly with much reduced exhaust emissions. With these unique features ,they offer signifcant economic, safety and environmental advantages to society, but unfortunately, the routines and the emergency procedures of the azimuthing podded propulsion system were not clearly defned and incorporated into onboard ISM systems. Masters, Chief Engineers and Pilots should receive a specialist training before they lay their hands on the controls, but instead most of them still have to try learning on the job, which sometimes lead to serious incidents, near misses and accidents with serious consequences. One of the reasons that encouraged me to write this book is to draw attention to these serious shortcomings which someday may cause society to pay a high price. My main focus in this book has been on telling about the shiphandling behaviours of electrically-driven azimuthing propulsors rather than the mechanically-driven azimuthing propulsors. Despite the fact that the shiphandling principles of both systems are quite similar, I chose not to mention much about the mechanically driven azimuthing propulsors as they are mostly related with tugboats. Tugboat handling is another speciality, which I believe should be explained only by seasoned tugboat captains themselves. I am a professional maritime pilot but an amateur author and this book is solely intended to share my humble experience and knowledge with my colleagues, ship captains, students and all other interested parties of the maritime industry. Dear Reader, I had actually started writing this book in order to keep my experience on the subject in writing and bring together all the data I have collected from various resources at different times. To improve my knowledge and experience, I have also joined a special manned model course for “Pod Handling and Emergencies” at Port Revel Shiphandling Centre which is located at Grenoble, France in May 2010. Vessels ftted with azimuthing podded propulsors have much better manoeuvring capabilities, such as reduced turning diameters and signifcantly shorter stopping distances compared to the conventional systems with a fxed propeller and conventional rudder. They are also environmentally friendly with much reduced exhaust emissions. With these unique features ,they offer signifcant economic, safety and environmental advantages to society, but unfortunately, the routines and the emergency procedures of the azimuthing podded propulsion system were not clearly defned and incorporated into onboard ISM systems. Even class surveyors and Port State surveyors don’t seem to have enough knowledge about this technology. Masters, Chief Engineers and Pilots should receive a specialist training before they lay their hands on the controls, but instead most of them still have to try learning on the job, which sometimes lead to serious incidents, near misses and accidents with serious consequences. One of the reasons that encouraged me to write this book is to draw attention to these serious shortcomings which someday may cause society to pay a high price.

Download or read book Shiphandling for the Mariner written by Daniel H. MacElrevey and published by Cornell Maritime Press/Tidewater Publishers. This book was released on 2004 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on large, modern commercial vessels. Unique in its emphasis on the art of shiphandling and manoeuvres for such vessels, it is a classic work designed to teach mariners and pilots practical shiphandling skills. The book is used as a text by maritime academies, shiphandling training facilities, ships' officers, and apprentice pilots. The text is a compendium of shiphandling information written by a father and son team of pilots, with contributions from several other pilots and shipmasters who provided material relating to their specialised skills. It is written primarily for the practising mariner -- the shipmaster, mate, naval or Coast Guard officer -- who already possesses some degree of professional knowledge, experience, and training. The text follows a non-technical format, stressing manoeuvres routinely used by working pilots and mariners. The material incorporates information from recent tests of the hydrodynamics of ship behaviour and simulator-developed data, with procedures and practices based on the authors' experience, gained while working as shipmasters, canal pilots, mooring masters, and river pilots. The fourth edition includes new information on squat and under-keel clearance in shallow water, bridge resource management for pilots, and discussions of new propulsion systems and hull types, including VMax ships and Azipod propulsion systems, proposals for a more modern approach to VTS, and laptop navigation systems for manoeuvring in pilot waters. Most manoeuvres used in docking, undocking, and shiphandling are covered, and many less commonly performed manoeuvres, including docking at single-point and multiple-buoy moorings, use of anchors in shiphandling, offshore lightering, and transiting of locks and canals. Good bridge practices in pilot waters and training techniques, including simulator training, are discussed, so that the potential deck officer or master can develop the shiphandling skills essential to the marine profession.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1895 edition. Excerpt: ...surface, or wave, noticeable above a revolving screw. In an account of the speed trial of the triple-screw U. S. S. "Columbia" the following is related: "The most noticeable feature of the trial of the ship itself was the remarkable absence of all wave. The triangular foaming cataract at the stern formed with its apex about ten feet from the ship and then subsided in height as it spread in width, until it disappeared fifty feet further aft into a series of gentle waves, similar to those which are seen in the wake of a stern-wheel steamboat." In some instances where the screws revolve very rapidly, and the form of the after part of the vessel and position of the screws are favorable for it, the elevation resulting from the discharge of screws is excessive. In the case of the torpedo boat " Cushing " it attains a height of three or four feet above the normal surface. When the immersion of the screw is sufficient, there may be little or no noticeable elevation of surface over it, because the discharged water will be widely dispersed and equilibrium will be restored before the surface can be affected to a sensible degree. In Trans. Inst. Nav. Arch., 1879, Mr. Griffiths recites the results of experiments he was allowed to make on H. M. steam pinnace No. 22 in 1875 by measuring, with apparatus specially constructed for the purpose, the rate at which the water flowed through the screw disk while the boat was being towed. These experiments showed that over the bottom half the water was little interfered with, but at the top half of the disk the water was dragged with the boat to a certain extent, and only flowed through the screw at about half the speed of the boat's progress. When a ship is being driven by a screw...

Book excerpt: Excerpt from The Screw Propeller: And Other Competing Instruments for Marine Propulsion Some thirty-two years ago, when engaged in putting forth the Manual of Marine Engineering, I could not find a single book on the Screw Propeller, or any text book containing such information on it as would enable a draughtsman to get out the leading dimensions, and much less to make a complete design of a screw suitable for any particular ship and conditions. At that time John Bourne's admirable book on the Screw Propeller was not only out of print, but out of date, and I fear no engineer could at any time have designed a screw which would give satisfactory results from what was contained in it. It was, however, many years after that I first saw his work, and my wonder then, as now, is that such a book was allowed to disappear, seeing how much of interest it contained. But perhaps the strongest comment on the knowledge of the screw propeller at that time is in the admission of the then engineer-in-chief of the British Navy, that he had settled the design of those for so very important a ship as the Iris, intended to be the fastest ship in the Navy, by copying that of hms. Himalaya, a ship built in 1854, with the result that the British Admiralty, with all its knowledge and opportunities, with all its records of tests and trials, perpetrated a blunder never equalled in the history of steam navigation, although in the mercantile marine there had been not a few mistakes. But even in modern times, notwithstanding the better knowledge and the aid of tank experiments, our best men do sometimes fail to achieve success, but the magnitude of the failure is inconsiderable compared with that of the Iris. In the Manual of Marine Engineering I attempted to supply the wants of designers by giving a rule or formula for each important dimension, generally based on scientific reasons, and always capable of giving results agreeable with the best and most successful practice.
