The notation also indicates that the gas-fuelled machinery has been constructed, arranged, installed and tested in accordance with the relevant requirements of Chapter 16 of LR’s Rules for Ships for Liquefied Gases, or is equivalent thereto. The low flashpoint fuel (or fuels) that the ship is designed to operate on is (are) indicated in the notation using a two letter identifier:
