Reduction of LNG Carrier Methane Emissions/Сокращение выбросов метана газовозами СПГ

Издание на английском языке
This guide focuses on reducing methane emissions—the main component of liquefied natural gas (LNG)—from cargo ships. It describes the main sources of methane leaks and methods for minimizing them during design and operation. It focuses on technologies used on large vessels and provides recommendations applicable to various types of LNG vessels. The guide helps shipowners and operators improve the environmental performance of LNG transportation by focusing exclusively on methane emissions, ignoring other greenhouse gases.
