Here is the absolutely latest electronic release of the SOLAS Convention. Of all internationally recognized conventions that have been ever developed and released by the International Maritime Organization in connection with the maritime safety, this one is deservedly considered as the most important since the content of the document covers the whole range of the technical and organizational measures and arrangements to improve the shipping safety, protecting the human life at sea.

The very first edition of the convention took place back in 1914, following the famous disaster of the “unsinkable” Titanic which resulted in the tragic loss of more than 1500 human lives. Four editions of the conventions followed since then and the present version of the document was adopted in 1974 and it has been in force since 1980.

The main intention of the present 2020 release was to provide all interested parties with the easier references to all recently introduced requirements that are applicable starting from January 2020. Note that the 1978 and 1988 Protocols have also been included, together with the Unified Interpretations, or UI, to SOLAS regulations. The arrangement of material is traditional for all released of the convention.

There have been so many publications about the carriage of the first cargoes of liquefied natural gas (LNG) onboard the Methane Pioneer in 1959. But what of liquefied petroleum gas (LPG), a gas ship cargo which predates LNG? When were the pioneering LPG cargoes carried and how did this important seaborne trade develop? In this tribute to the first gas carriers, Robin Gray, former SIGTTO General Manager, sheds light on the early days of the less well-known part of the gas shipping industry and on the role played by one particular shipyard in the North East of England.

This paper by Robin Gray, former general manager of SIGTTO, provides some historical background, touching the post-war development, addresses the major conversions of the vessels and famous conversion projects, applicable rules and patterns, liability insurance and cargo familiarity, material used for the construction and insulation of the cargo tanks, integrated gas distribution, propane loading problems, local gas trials, ethylene-related issues, training provided to the officers, fire protection tests, cooldown tanks, welding problems etc. Have a look into this document since the information contained in it is useful and practical.

The present DP induction course by Beier Radio has the following important objectives - the first and maybe most important of them is to provide the trainees enrolled with a good and thorough understanding of the DP principles, while the others include the demonstration of the proper setting-up as well as the operating of the various dynamic positioning equipment plus position measuring equipment, assistance in the recognizing and further responding to the warnings, alarms, and info messages received, examination and analysis of the relationships existing there between the dynamic positioning equipment and the ship systems, and even relating of the dynamic positioning operations to the different environmental conditions expected to be faced by the vessel.

The content of this training program was developed on the basis of the professional principles, specified objectives and important practical elements. Some part of the course is directly concerned with the assessment of the DP operator's competence from the shore-based organizations to the vessel...

Nowadays, most of the vessels sailing the world's oceans are propelled by diesel engines. These engines provide maximum possible effect on a real minimum fuel oil consumption, of course provided they are given good technical care and kept well maintained.

The engineers may easily note that at the moment they are checking the current temperatures of the exhaust gases and cooling water. To make a more detailed further study of this marine diesel engine, let us leave the engineer with his instruments by the engine, and put sight glasses on the marine diesel engine from its top to bottom.

This will first of all reveal the moveable parts of the engine, namely pistons and piston rods, crossheads and crankshaft, connecting rod and many others... This video was prepared by B&W specialists and contains very useful technical information for all people dealing with the marine diesel engines.

The book provides readers with a good insight into the fundamental processes that regulate the marine carbon cycle. The content of the volume is offering a required background in chemical oceanography; in addition to that, it provides readers with the clear description of the way chemical elements contained in  sea water and sediments are actually used as tracers of various processes occurring in the oceans - and these processes are biological, geological, physical and chemical.

The chapters of the book are covering the basics of thermodynamics, carbonate chemistry, they provide the explanation of the influence of life on the chemistry of the ocean and how exactly it evolved in the past. There are some topics in the book that contain essential information for understanding the idea of the carbon cycle, including such important aspects as exchange of gas within the air-sea system, organic geo-chemistry, reaction kinetics, diffusion, and so many of other relevant matters. The title will be really ideal to serve as a textbook for all students in geo-chemistry, oceanography, marine science, environmental science and any other fields. It will also be useful for the professionals and scientists in the field and actually to any persons involved in the relevant researches. 

From the very early times of hieroglyphic writing and up to the modern graphics, people have always understood the need to represent their thoughts and discoveries as well as the inventions in order to keep the other people informed. As the human civilization is becoming increasingly complex, its graphic representation which is paralleling both science and engineering is also becoming more complex.

Graphics is definitely a lifeline for the engineers since is connects their thoughts, inventions and researches with the actualities coming as a result. In order to keep in line with all advances in engineering and sciences, graphics has always been and is still being refined in different ways. In the past, it emphasized the drawings as a communication language. The present textbook is going to promote the traditional conception. The text of the publication has been arranged in three major portions.

The first portion deals with the engineering drawing together with the projection basics and communication, while the second portion addresses the descriptive geometry and solution of the various space problems. In turn, the third and last portion of the book covers the graphical solutions as well as the solutions of math problems presenting the particular interest to the practicing engineers.
