Digital Ship Magazine - December 2017-January 2018
The best maritime and offshore library
In maritime shipping industry of today, the suppliers of bunker fuel tend to employ different dubious practices for the typical operations, and subject malpractices are commonly prevalent in Asian region. Regardless of where the ship is being bunkered, the huge importance of proper and accurate measuring the fuel tanks both prior to and upon completion of the delivery is considered critical phase of all bunker stem operations.
That is why attention shall be paid by the members of the bunkering team taking the barge measurements to the application of the proper trim and list and recording the real temperature of the fuel. Some of the ways of concealing fuel would include hidden compartments and altered lengths of the sounding pipes, short bunker delivery and incorrect sounding tables, doctored gauging devices and others.
The present guidebook prepared by MarineInsight experts shall therefore be of great practical use for the people directly participating in the bunkering process. Apart from the description of different malpractices, the book will provide tips to get better understanding of the bunker gravitating and so-called cappuccino effect, coriolis flow meters, bunker surveys and also different methods and techniques used for detecting concealment of the fuel.
These Rules were developed and officially released by the China Register to be used for providing effective service for the certification of the ship security system. The content will be applicable to the security systems of passenger ships including HSPC, i.e. high-speed passenger crafts, cargo ships including HSC with the gross tonnage not less than five hundred tons, and MODU, standing for the mobile offshore drilling units.
The material contained in the rulebook has been arranged in four chapters. The first chapter is introductory which is quite standard for class publications. The second chapter is devoted to the certification process and documentation involved. The third chapter is dealing with the approval of SSP, i.e. ship security plan, covering general requirements and review of documents involved as well as approval for the SSP amendments.
The closing chapter addresses the SSP audit including general information, initial, periodical, additional and interim verification. Three appendices at the end of the book provide minimum requirements to the ISPS certification scenarios, and forms of the ISSC and Interim ISSC. A needful volume for the people engaged in associated activities.
The latest release of the official GMDSS Manual. The present publication is published with the intention to provide, in a single and comprehensive volume, a thorough explanation of the principles upon which the GMDSS bases as well as to describe the radio-communication requirements together with the recommendations for implementation of the system, relevant operational performance standards supplemented by the technical specifications that shall be met by the GMDSS related equipment.
The document also covers the methods and procedures for the operation of the radio services forming the GMDSS. The Master Plan for the system has also been addressed. This edition of the Manual is fully updated. The content of the publication includes description of the technical concepts and history of development of the GMDSS, valuable excerpts taken from the relevant regulations of SOLAS convention, supporting regulatory documents such as circulars and resolutions related to the GMDSS.
In addition, there are ITU recommendations providing required technical details, the NAVTEX Manual, and many other information considered important and relevant enough for inclusion - in fact everything you need to be able to understand and use the GMDSS. The volume shall be used by the vessel personnel, shore supporting persons, regulatory bodies, administrations and all others engaged in ship communication in any way.
And here is the closing part of the world popular and respected training series devoted to the entry into enclosed spaces. This part is dealing with the correct use of breathing apparatus and is supplemented with this training video. The content of the publication has been arranged in seven sections.
While the first section gives some overview of the breathing apparatus commonly used on board vessels and offshore installations, the second section provides necessary instruction on their examination and assembly, and this has to be conducted on the regular basis to ensure that the equipment is fit for service and ready for immediate use.
The other sections of the volume are dealing with the bench testing and proper donning the breathing apparatus set, followed by the familiarization and practice information, and instructions to conducting training and drills. The closing section lists the resources. Assessment questions and answers included. Note that all other parts of the training series are also available and cover the Awareness, Preparation and Procedures, Equipment, and Enclosed Space Entry itself and finally Emergency Procedures and Rescue. We recommend you to download the whole set and go through it very carefully.
The last part of the training series, and this one is devoted to the correct use of the BA, standing for the breathing apparatus, in the course of the emergency and rescue operations. In our job, we get plenty of fresh air and the air contains oxygen meaning to stay alive, but just how much air do we need? It depends on the body's energy requirements. During rest, we may only use sixteen to twenty liters a minute.
But, if you are wearing breathing apparatus, in an emergency this can rise to forty liters of fresh air peach minute due to the raised stress level of the wearer. If extra-heavy work is performed at the same time, fifty to sixty liters of air may be consumed. But why? When physical effort is required, the body needs more oxygen. Fresh air contains twenty-one per cent oxygen; this will never change.
So, the only way of getting more oxygen is to increase breathing rate... Check the accompanying training booklet on the correct use of BA and, of course, feel free to download and go through the content of all previously released training videos belonging to the Entry Into Enclosed Spaces series and covering the Awareness, Preparation and Procedures, Equipment, Enclosed Space Entry itself and Emergency Procedures and Rescue.
This thirteenth technical information paper issued by the ITOPF is dealing with the effects that the oil pollution has on the marine environment. The spills affect the marine environment in a very serious way, this combines the toxic effects and physical smothering. And the severity of their compact commonly depends on both type of the spilt oil and its quantity as well as of the ambient conditions.
Moreover, we have to take into account the sensitivity of the organisms and their habitats affected by the spills. This document was released to describe all the effects f the vessel-source marine oil spills and of the subsequent clean-up activities on the marine flora/fauna. The authors have paid particular attention to the discussion on the complex interactions between the bio-systems and the oil.
The marine oil spills are often referred to by the media as the environmental disasters having extremely negative consequences for the flora and fauna of the sea. The impacts of the spills have been seriously and closely studies by the scientists and the results of the studies are now presented in the numerous technical and scientific publications available today. It means that now we understand all consequences of the oil pollution and the duration and scale of the damage involved...
This is another classic publication on marine navigation. The book was first published in early twentieth century, namely back in 1902, and today it is deservedly treated as a very valuable historical work. The present book is intended to be used exclusively by the sailors and its content was compiled on the basis of the author's experience of sailing and ship navigation.
One of the recognized navigation experts of his times, the author managed to collect all information on the ship navigation, process it and present in a form of the textbook providing readily available instructions and tips. The volume is covering absolutely all areas and this makes it very useful and practical even to the navigators and students of today.
Of course, one shall understand the difference in the techniques and especially navigational equipment and systems available at those times and today, but we do understand that theoretical fundamentals of ship navigation have not significantly changed since then. The text part of the treatise is accompanied with the numerous data diagrams and tables. An absolutely recommended and must-have publication for every professional and future ship navigator.
