This document provides guidance to assist the gas shipping industry in its efforts to reduce methane emissions from LNG carriers. Methane is a greenhouse gas (GHG), and it is vital to minimise the environmental impact from the transportation of liquefied gas. This is the first document in a series that plans to address this issue. As a first step, this document provides guidance on the detection and reporting of fugitive methane emissions.
The main purpose of this document is to recommend that a structured system is set up to identify, detect, measure and quantify fugitive emissions of methane from LNG carriers. This is an important primary step that may also support a more comprehensive leak detection and repair (LDAR) system that is intended to reduce emissions through maintenance and design improvements.
