Marine Engineering

As it is implied by the title, this publication prepared and distributed by the professionals of the world popular and famous Marine Insight community, is mainly dedicated to the piping found on board ships and other floating structures. In fact, it is a brilliant compilation of series of interesting articles on this subject prepared written by one of the contributors of the website.

The marine engineer is responsible for all operations taking place in the engine room of the vessel and of the proper watchkeeping. As a rule, marine engineer shall have a very good technical knowledge of all piping and fittings installed on his ship - this applies to both new construction and repair works. Sometimes it makes difficulty for the people to distinguish between tubes and pipes. It shall be noted that, though the meanings are quite similar, these terms are not synonyms.

The difference is based on the fundamental rules of pipes and tubes nomenclature. In short, this publication will be of great interest to people involved in the new construction of the ships, maintenance and necessary repair of the ship's pipeworks. The book has been divided into five major chapters addressing basics of the pipes, pipe bends and elbows, types of nipple, adapters and tees, and miscellaneous pipe fittings.

This training booklet is devoted to the powered watertight doors installed on board ships; subject doors are deservedly considered critically important for the safety of the vessel. They are usually very powerful and heavy - should they be used incorrectly, these doors can easily harm and even kill people.

That is why every single person on board the ship must have thorough understanding of the risks that are associated with them; all crew members shall also clearly know how these doors shall be operated to avoid such risks. The powered watertight doors of sliding type are normally fitted in watertight bulkheads subdividing the hull of the passenger, Ro-Ro and other vessels in watertight compartments. They are installed to allow ship crew to move from one such compartment to another and, what is very important, to prevent spreading of the water through the hull in case of flooding.

Should the water ingress in one watertight compartment, the closed door contains it in within that compartment and does not allow to flood further. Long story short, these doors play the critically important role in provision of the watertight integrity of the ship's hull and, consequently, provision of the safety of all people on board. You may use this training video with the booklet.

The book offers all readers (including the industry professionals, researchers and students) a good and practical guidance, thanks to the technically oriented approach that has been applied by the author, and inclusion of the many innovative findings as well as observations. All the explanations provided in this volume are presented in quite understandable language and the well-thought layout of the book makes it reader-friendly, that is why it has gained popularity in the industry.

Nowadays, the heat pipes are deservedly considered one of the best technical solutions available for the passive thermal control, note they are also very friendly to the environment. The present publication comprises a work by the industry expert Bahman Zohuri, who did his best to provide readers with the useful practical study of heat pipe engineering including a very valuable discussion on how the application of the heat pipes could be further optimized and made more efficient.

The book provides a general introduction to the design and operational principles and explores the practical applications of heat pipes. The volume offers the readers a good tech review of mass and heat transfer theory related to the performance and covers the common technical issues that might theoretically affect the successful operation of the heat pipes. Subject matters would generally include balancing of the loads, compatibility of the construction materials, applicable power limitations, thermal resistance issues, rage of the operating temperature, and operating orientation.

The author has also compared the results of the calculations with the experimental data obtained from numerous sources. He has also provided the explanation to the readers of where and how exactly they could access the computer codes and relevant PC programs to the design and prediction of the performance.

The present pump handbook was specifically prepared and officially released by Alfa Laval professionals with the intention to provide all required support the users of the pumps at all levels and to provide them with the very valuable reference tool.

This publication is covering all relevant technical aspects and includes all info considered necessary for the proper selection as well as further application of the "Alfa Laval" ranges of the three basic types of pumps - namely the centrifugal pumps, the liquid ring pumps, and the rotary lobe pumps. This handbook has been arranged in fifteen main chapters - the first chapter of the book will give some very basic intro to above stated types of pumps, while the second chapter supplements that information with some theory and terminology.

The remaining sections of the handbook address the selection of pumps, description of the pumps together with their working principles and nomenclature of the parts, materials that pumps are constructed of, sizing of the pumps, specification options, pump motors, some cleaning guidelines, tips to ensure compliance with the recognized international guidelines and standards, installation and troubleshooting guides and relevant technical data; in addition to the information listed above, the handbook contains a good glossary of terms.​

The present volume has been specifically designed in a form of the reference source intended to assist the process designers and personnel using the decanters. It shall aim to eliminate the existing info gap in the subject field - the gap that is there between academic theory being promoted in the relevant student textbooks and data provided within the numerous case studies in manufacturers documents.

The publication contains valuable technical information directly related not only to the design but also to the specification that will prepare readers to select the equipment and size it correctly. The users would also be provided with the full facts before they commence the ordering process and communicating with the vendors, thus enabling them to have a full picture. The book will also allow readers to track suppliers of the associated equipment and get a basis on which they can find new relevant companies for the parts or services to be ordered.

Moreover, this publication is also covering all relevant process operating issues, for example instrumentation/control, use of flocculent and others. Definitely recommended to all people dealing with the above mentioned activities and required to possess a proper understanding of all related matters.

This publication is for anyone who are working with boilers, for example the power plant managers and maintenance technicians, boiler operators and utilities managers plus other involved personnel. The information presented in the volume is primarily dealing with the boilers of "water-tube" type with both induced and forced draft fans as well as the boilers with only forced draft fan.

It should be noted, however, that this volume can also be applicable to any steam generator that requires the fuel firing. The author of the book has addressed the major issues that must be considered as necessary in order to define the measurement transmitters and preparing the specification. The final control elements have been reviewed according to the sizing and characteristics.

The book also covers the engineering details of the boiler control systems and the procedure for setting-up of the control functions; the text is supplemented with numerous specific examples of boiler control, tuning and configuration. Moreover, the publication also provides interested people with the primary requirements to a BMS (i.e. burner management system) of the boilers. Needless to say, this is a remarkably handy reference tool for all persons involved in any way in the operation/maintenance of the boilers.

This is an official reference document that was worked out by the professionals of Wilhelmsen and released by the company in order to provide the best technical description of the available methods for testing the fuel oil and lubricating. It also provides some basic theoretical information, explaining what exactly the TBN, i.e. the Total Base

Number is and how it shall be determined - this can be achieved by means of taking measurements of the pressure build-up occurring in the cell at the time when some pre-determined quantity of oil sample is being added to a special reagent. Then, the amount of sample required by the cell measurement processor is to be determined; and  this amount bases on the expected Total Base Number.

When this instrument is used for the very first time, please take into account that it is absolutely necessary to calibrate it for each of the measured oil grades. The cell is able to hold the calibration information for up to seven different grades of oil. It is recommended to use the name of the oil grade the "Name" in the process of setting-up the cell. Note that you will have to re-calibrate the cell every half a year.

The calibration could be checked by using new oil in the Total Base Number test procedure, in place of the one used. The'test'TBN should be close to the new oil TBN.
