Floating Offshore Liquefied Gas Terminals/Плавучие морские терминалы сжиженного газа

Издание на английском языке
The document outlines the ABS Requirements for Building and Classing Floating Offshore Liquefied Gas Terminals, based on extensive experience with LNG carriers and floating production storage and offloading units (FPSOs). It provides criteria for classifying the hull and tank structures of floating gas terminals equipped with membrane or independent prismatic tanks. The guidelines apply to both ship-shaped and barge-shaped hull forms with specific cargo tank arrangements and emphasize the importance of industry collaboration in adapting to advancements in offshore gas terminal technology.
The document presents alternative hull strength criteria compared to existing ABS Marine Vessel Rules, allowing owners to choose between this new document and the prior regulations, but not to mix criteria within the same design. Recent editions have introduced notations for fatigue life in mooring systems, applied to converted terminals, and provided requirements for topside module structures, with the latest version transitioning from a guide to a requirements document, thus establishing mandatory classification criteria. Users are encouraged to verify they are using the most current version available on the ABS website.
