In order to continue meeting and supporting the market in its growing demand for cleaner fuels and versatile LNG applications, DNV GL has updated its RP for Development and operation of LNG bunkering facilities (DNVGL-RP-G105). The RP now includes a section dedicated to determining LNG quantity and its properties. The objective is to assist operators in addressing the large spread in properties, density and the calorific value among the available LNG sources globally.  

The RP focuses on four main elements: 

  • Safe design and operation
  • Safety management systems
  • Risk assessments 
  • Gas quality and quantity metering. 

The RP is in accordance with, but further elaborates on the ISO/TS 18683 Guidelines for systems and installations for supply of LNG as fuel to ships, with focus on bridging the gap between the rules for the receiving ship and the bunker supplier, such as national or port regulations and rules for LNG bunker vessels.
