A HISTORY OF SEAMANSHIP

This is one of the most successful and popular books on the history of seamanship. We all understand that it would be next to impossible to try and write a complete and truly comprehensive history of the seamanship in a single volume. However, the author of this publication has managed to provide readers with an excellent and very interesting work. The seamanship itself began so many centuries ago - no one knows when exactly but people believe that happened in the Stone Age.

The content of this book will lead the readers through the whole history of seamanship starting from the old-time boats and up to the modern nuclear powered ships navigated by electronics. What the author did is that he arranged the material presented to the readers in six separate chapters, each of them covering one particular period of the history. The opening chapter is dealing with the earliest days of seamanship while in the second chapter we move to the antiquity.

The last chapter covers the times of the mechanical revolution. The main body of the volume is supplemented with the compact glossary of seamanship terminology which will be definitely appreciated by the people relatively new to the maritime world. Numerous brilliant photographs and images are there to provide additional information making it even more interesting to read.

Concrete in Shipbuilding

Let us talk a bit more about the application of non-ferrous materials in ship construction. The previous article covered the use of the GRP while in this one we will deal with concrete. Concrete consists of a mixture of stone aggregate bonded by a hardened cement, and Portland cement is normally used for marine applications. The aggregate consists of sand, gravel, and crushed stone. Specific gravity of concrete normally varies between 2.2 and 2.5, primarily depending upon the sizes and density in the stone mixture. Lighter weight concrete with specific gravities in the 1.6 to 2.0 range are made by using clay and shale aggregate. The ratio of water to cement is one of the most significant factors in determining concrete quality and properties.

Ordinary structural concrete with a water/cement/ratio approximating 0.40 by weight is usual for marine work. The long term durability of concrete in sea water has been well established on the basis of service experience and testing of samples from structures that have been submerged. However, in certain situations when concrete is ex¬posed to sulfate in soils or fresh water, it may react with the sulfate, and degrade. Sea water, however, minimizes or prevents such deterioration. Where sulfate deterioration is of concern, special sulfate resistant concretes are used.

Ferrocement

Ferrocement is a form of reinforced concrete wherein layers of steel mesh are used as the reinforcing medium. The material has been used for making small boats up to 50m with skin thickness of 10 mm to 40 mm. The low cost and availability of the mesh and concrete ingredients make ferrocement particularly attractive where sophisticated industrial facilities are not available. Its most extensive commercial use has been for fishing vessels up to 50 m in length.

ECDIS VOYAGE PLANNING

There are four main learning objectives declared by the developers of this training module. First of all, the trainees will understand what the voyage planning is and why we should have it at all. Then, they will get to know everything about the responsibilities of the company in connection with providing their people with appropriate instructions and procedures.

In addition to that, all important factors that shall be considered when making a decision on the appropriate route have been covered. Finally, this module will tell them about the fundamental principles of the voyage planning and shed some light on execution of the plan both with and without the ECDIS system available.

The main purpose of the voyage planning is to provide adequate preparation for the intended voyage with the due attention paid by the bridge team to the voyage and also to make sure that the vessel will be navigated in a safe manner. A proper voyage plan will provide a good coverage of the pilotage, coastal and ocean waters. Of course, the navigators shall be appropriately briefed with regard to the intended navigation. Should the voyage plan have to be amended, the navigators shall be made of these changes.

Glass Reinforced Plastics in Shipbuilding

In the present article we will have a short talk about one of the non-metallic materials used for construction ship hulls. Though not used in ship building as widely as the steel, for instance, the these plastics are becoming more are more popular and therefore deserve due attention of the ship designers and shipbuilders.

Glass reinforced plastics, GRP, are a form of fiber reinforced plastics, FRP, which were introduced for marine structural applications in the 1940's in the form of Navy personnel boats. Since that time GRP have found widespread acceptance for yachts and small boats such as fishing trawlers up to 34 m in length. Although the future of glass reinforced plastics for larger ship structures is very promising, economic factors, and to some degree, questions of durability, limit their applicability.

Reinforced plastics used for ship structures are composed of glass fibers embedded in unsaturated polyester resins. Properties of GRP that are particularly useful for marine service, and have led to their extensive use for small boats, are high strength-to-weight ratio combined with good resistance to deterioration upon prolonged exposure to sea water. Lower maintenance costs for GRP hulls compensate for their relatively high initial cost as compared with steel or wood.

COMPUTATIONAL SHIP DESIGN

The present volume will offer its reader an excellent introduction to the very fundamental processes and also important systematic methodologies that are normally employed in the popular and effective computational approaches to the design of ships. The authors of the book are taking a detailed approach providing detailed descriptions of the relevant theories and definition of the problems, selection of the algorithms and math formulations etc.

The content of the publication is covering the whole ship design process starting from description of the basic theories and up to the latest applications. While the opening chapter is dealing with the basic models and equations of the ship design together with the freeboard calculations, hull resistance and powering of the ship, the other chapters are covering ship propeller design and ship hull form, selection of the engine, structural design and other relevant aspects.

The last two chapters address the operating ship design and consider the economic factors such as fuel consumption and construction cost. The volume is reflecting the huge practical experience of the authors in the field of ship design and s therefore recommended to any person engaged in the shipbuilding.

ECDIS VIDEO GUIDES — KONGSBERG K—BRIDGE

This collection of training videos will provide users with all necessary instructions related to the Kongsberg K-Bridge system. The arrangement of the content is nearly similar to the one of the pack dealing with the JRC system. The first of the video lessons is introductory and tells you how to find your UPN, standing for the User Permit Number. The second and third lessons cover deleting of the ENC data and permits.

The other five lessons making the pack are dealing with the same subjects as in the JRC training, i.e. installing the public key for the S-63 1.1, ENC permits, AVCS base and update CD media, and finally the DVD media. Needless to say that this training package will be of great practical interest and use for all crew members immediately involved in the installation and use of the system.

However, taking into account the information it provides and clarity and conciseness of the explanations and descriptions provided in these videos, we would say that it will be good for any navigator to acquaint himself or herself with the content. Even if you have some other ECDIS system installed on your ship, understanding of the fundamental concept and different systems will give them a good advantage.

CRANES, THEIR OPERATION AND REASON FOR FAILURES

This publication was prepared and released by the Japan P&I Club. The intention of the authors was to give some brief introduction to the shipboard cranes and their operation, with due attention paid to the most common reasons for their failures. This compact title provides general guidelines on the routine maintenance and inspections of the cranes. The structure and machinery of the cranes have been discussed together with the wire ropes.

Then the content proceeds to the crane operation and the incidents that involve crane damage. The grabs have been discussed separately together with their capacity, SWL and use. And of course, the authors concentrated on safety matters as well. The cargo handling cranes are installed on most of the vessels, especially general cargo ships and bulk carriers.

They are normally quite robust units continuing to work with nearly minimum maintenance; however, they are complex machinery units incorporating many components that are manufactured to the fine tolerance values. All of the components shall function correctly through the entire lifetime of the crane. The cranes shall be duly maintained and checked at a specified time intervals to make sure they are operated safely and correctly.
