Liquefied Gases Handling


The known and researched world gas reserves exceed those of oil. However, for so many years the gas has not attracted too much interest. It was rather considered a sort of hindrance by the people engaged in the oil recovery. The associated gas used to be flared. The wells containing no oil but a plenty of gas used to be totally ignored. The first practical attempts for gas production were made at the beginning of the last century.

People had finally recognized the potential of gas reserves to change the way of their living. The development of gas reserves has eventually led to the need for its transportation which, noting its flammable nature, should be carried out in a safest way. The present publication provides a good review of the marine LNG transportation as well as of the conditions that prevail today.

Without going too deep into technical details of the transportation, the author gives a nice overview of all important aspects including the characteristics of the vessels engaged in transportation, current regulations and rules governing it, gas storage ashore and of course safety considerations. The readers will find valuable information about everything associated with marine transportation of gas from both safety, technical and commercial perspectives.

An excellent publication released by the world respected SIGTTO organization. As it is clear from the title, the content of the volume is intended to provide necessary information and instructions on the fire hazard management on board ships transporting liquefied gases. The authors have managed to bring together, in one informative volume, the main principles of preventing and fighting the fires associated with liquefied gas.

The volume is mainly aimed at the operational staff including ship officers and plant supervisors since they are directly engaged in the handling of the liquefied gases that are very flammable. However, we would highly recommend it to the fire officers as well as to the emergency planners - they will be provided with a good professional insight into both technical design and practical operation of the liquefied gas installations together with all equipment considered fundamental for safe and efficient operation of those installations.

Numerous real life case histories make the content of the publication even more readable. In short, we can say that the authors have managed to cover absolutely all important aspects of the topic, and this approach has gained worldwide popularity to their work which is deservedly treated as one of the best books on the subject. The analysis of the famous incidents, such as the propylene fire on board Val Rosandra and attack on Gas Fountain, and others.

This publication developed by the professionals of the SIGTTO organization was intended to advise the people engaged in the works on board gas carriers on the proper procedures relating to the technical maintenance of the PRVs, standing for the pressure relief valves, address various operation problems, possible faults and emergency closure.

The idea of the authors was to provide some general guidance to the crew members of the vessels - note that the volume is not expected to replace any of the instructions or manuals provided by the manufacturers of the equipment in question.

Opening with some introduction, the content of the volume covers the general requirements that are applicable to the PRVs including requirements to their design and installation on board. The types of the PRVs are addressed in detail, covering both spring operated and pilot operated pressure relief valves. The emergency closure of the PRVs is considered particularly important and is therefore dealt with in a separate chapter.

The publication also covers the in-service testing of the valves. Five appendices provide additional information including extracts from the IMO IGC Code, pressure levels, terminology and definitions used etc.

The content of the present handbook is providing the result of the cooperative work of the group of experts. Their intention was to create a book that would facilitate better understanding to be shared between the government officials and the companies of the various economic, commercial and technical aspects.

Note that the authors of the volume did not intend to deal with promotion of any particular business model; their idea was rather help stakeholders better understand their aims in developing the LNG projects and opening future LNG trade markets. The volume provides a good framework for evaluation of the LNG projects considered important, and this is applicable to both importers and exporters of the natural gas.

The authors hope that the information provided in this volume together with any following dialogues that this volume engenders, will eventually improve the existing flow of information and help erect the human capacity accelerating the development of the natural gas, make the generation of the power cleaner, and promote energy security and further economic growth. The publication will be interesting to the people involved in the development of the natural gas and any related projects.

This officially released SIGTTO publication is intended to provide required guidance to the cargo strainer installations on board tankers carrying LPG cargoes. For many years, these strainers have not been in use since until now they have not been considered necessary equipment.

The reason for that was that the LNG cargo used to be treated as the "clean" one with the filtration commonly limited to the strainers fitted in the loading line at the time of the new construction, i.e. at the shipyard. The contamination on board the vessel was provided by good housekeeping combined with the regular visual checks during the installation and commissioning of the line, together with the post-delivery inspections at regular intervals.

However, the installation of the strainers is now a requirement to be complied with, noting the significant role they can play in preventing the pollution and maintaining the clean transfer of cargo - this is one of the most important parts of the process that is a key element in preventing damage to the terminal equipment as well as any serious contamination.

This document will provide readers with the recommendations that have been developed on the basis of the practical experience related to the different types of strainers, their location and performance..
