Fuel Ready

For owners who want to prepare their newbuilding for a potential later conversion to alternative fuels: LNG, LPG, Methanol or Ammonia. The additional class notation Fuel Ready has supplementary levels and corresponding requirements. The minimum mandatory levels include:

• Verification of compliance with Fuel Ready rules for the selected fuel. More than one fuels can be selected.
  
• The main tank(s) installed can be converted to gas or dual fuel operation (or are of dual fuel type from newbuilding stage).
  

In addition, optional levels may be included, i.e. it can be chosen to include different preparations of the ship for a later conversion and include certification and installation of parts of the alternative fuel systems in the newbuilding phase.
