Guidance Manual for Tanker Structures, 2024 Consolidated Edition/Руководство по конструкциям танкеров, сборник 2024 года

Книга на английском языке
This publication is based on the experience and methods used by members of the Tanker Structure Co-operative Forum (TSCF), which includes shipowners, operators and classification societies. The 300-page book compiles the information needed to evaluate ballast and cargo tanker designs and covers survey preparation and execution guidelines, maintenance guidelines, and survey data analysis.
