An excellent video training officially provided by Walport International and covering the key points of the management and particularly treatment of the ballast water. We are all aware of the IMO requirement of "ninety-five percent volumetric exchange" of the ballast water in the ocean - and there are three IMO approved ways in which requirement can be met.

First, by the "sequential" method - here, the ballast tank is first emptied, and then it is filled with replacement ballast water. The second method is called the "flow-through" method - here, they pump the water into the ballast tank and allow it to overflow; note that pumping through three times the tank's volume is considered to meet that ninety-five percent target of exchanged water. Third - the "dilution" method - in this one, a constant level of water in the ballast tank is maintained while water is both pumped in at the top and simultaneously discharged from the bottom. Again, three times a tank volume is usually considered sufficient to meet IMO standards.

The IMO BWM Convention addressing the issues of management and control of ballast water provides captains with another option - on board treatment of the ballast water. Filter out those bio-stowaways with some other IMO approved treatment system and you can forget about ballast water exchange. Maybe, but not yet... The system is still coming and it is getting closer, and what it means is that in some ten years the ballast exchange will be a thing of the past... A very good supplementary material for training of crew members and all people involved in the BWM, i.e. ballast water management.

The book was specifically prepared and published to introduce a new approach to the anchoring of large ships. The anchoring systems installed on board large ships are commonly designed within general technical parameters, namely with the anchor and anchor cable being capable of holding a fully loaded ship in a current with a three knots speed and a twenty-eight-knots wind max.

It shall be noted that these systems are not designed and are not supposed to stop a ship with way on, as subject momentum will for sure exceed the limit of the shipboard anchoring system. Generally, there are thirteen shackles and twelve shackles o the starboard and port anchors, correspondingly. The motor of the windlass is designed for the vertical lift of the three shackles plus the anchor's weight allowing for the fifty percent more when testing.  

The cable stoppers shall be able to carry nearly twice the proofload applied on the cable with the holding power of the windlass brake being nearly half of the cable breaking strength. The present monographs will describe the basic principles of all associated ship maneuvers and also discuss the limitations imposed to the shipboard anchoring systems which all prudent mariners shall be aware - a truly well-though content of the book makes it very useful.

The content of this introductory publication is intended to be of practical use for a broad range of the readers with the interest in marine radio communications. It will also be excellent for the self-learning and we would recommend to go through the pages of the volume prior to taking the formal GMDSS training courses. Individual limitations are commonly imposed to the radio- and satellite systems forming a part of the GMDSS system, relating to the availability and range.

To make sure that all required functions of communications are readily available at any time, the duplicates of the functions considered vital, for example warning, alerting and communications are included. The vessel in distress should be able to automatically alert the coastal state stations and RCC, standing for the rescue coordination centers. The warnings received by these stations will then be passed to the vessels located in that area. The special systems are taking care of the inter-ship communications.

The requirements applicable to the shipboard radio equipment will mainly depend on the area the vessel is currently sailing in. Four sea areas are defined within the GMDSS system. When distress message is sent to another vessel, or to a RCC, the latter is leading and coordinating the whole rescue operation...

The present Accident Investigation Course has been offered by Marlins. For a start, the users are prompted to enter their names, vessel/office, seaman's numbers and ranks. However, note that this is optional, i.e. if you want to use the program for yourself not being a seaman, feel free to enter any letters and proceed.

The aims of this course are to consider different accident types and their immediate and underlying causes, examine the most important stages in the process of accident investigation, outline the characteristic of an effective investigation, and highlight reasons for doing accident investigation. There are five major chapters inside - accidents, incidents and near misses; accident causes; introduction to accident investigation, key stages in accident investigation, and a good investigation. The glossary will provide users with the explanation of key terms used in this course.

The course examines the core nature of the accidents and describes how the accidents usually occur; it provides users with the guidance on how to perform the effective investigation and highlights the techniques of the interviews and recording them. It is highly recommended by the developers of this course to spend about two hours working on it for proper understanding of the material and satisfactory completion and assessment.

The present Code of Practice was developed by the ABB professionals in order to provide necessary technical guidance on proper safety planning for the operations on site. The authors did their best to produce the booklet giving the practical direction to the personnel involved in the crane works and make them achieve the ABB health & safety standards.

The book is mainly focused on site operations; however, the requirements that are set down also apply as a baseline for other operations. The material presented in the book shall be used for training purposes, and the requirements included therein, must be implemented as necessary. It may be used by project managers and sales when tendering for projects, and making the agreements with different parties. Note that the document presents the ABB's minimum standards; it bases on the ILO Code of Practice.

In case a national legislation (or customer requirements) set a higher standard, then the higher of the  standards must be used. It shall also be noted that some of the H&S risks may not be covered by this document. However, the paper is very useful to everyone willing to improve the safety awareness and get better idea of the crane operations on site.

Naval officers having some basic mathematical ability can easily make themselves familiar with the fundamental principles governing the design of the vessels and the most commonly used calculation methods; however, those willing to become naval constructors would require long and very patient apprenticeship of the shipyard.

The naval architecture addresses such the problems as how to make a vessel sail and carry weights, how to make the vessel stand right at sea and obey the commander, and go easily through the waves at a given speed, in fact everything connected with the construction of the vessels and prediction/calculation of their behavior at sea.

In fact, shipbuilding itself implies giving the materials of which the vessel is to be made of all the shapes, forms and dimensions, as well as strength and power characteristics required to make them fully comply with the conditions that have been already calculated by the naval architects. he naval architects, shipbuilders and marine engineers are representing three professional skills.

Their duties shall be performed successfully so that the duties of the newly built vessel may also be performed in a successful manner. All of these duties are considered essential but they do not have to be performed by three separate people... Have a look into this rare and classic book, you will not get disappointed, it is much more than a regular textbook.
