Guide for Vessels Intended To Carry Compressed Natural Gases In Bulk/Руководство по транспортировке морем сжиженного природного газа

Книга на английском языке.
This Guide provides requirements for design, construction and periodic surveys required for maintenance of classification that would be applicable to CNG carriers, where it is intended to obtain ABS class for the vessels. These requirements may also serve to satisfy Port State and Flag State Regulations as they develop. As these projects are still at the concept stage and various scenarios are being considered at this time, the objective will be to establish an overall philosophy or approach to provide a framework of reference material and cite precedence, where applicable, as to what methodologies followed by designers in similar projects have proven successful in the past.
