Gas as a fuel

LNG contributes to reduce GHG emissions and cost of ship fuel

Under the latest more stringent requirements about the control of NOx, SOx, CO2 and particulate matter emissions from ships’ exhaust gas, the use of LNG as fuel for propulsion and auxiliary systems on board, instead of the conventional fuel oil, is one of the solutions to be taken in due consideration.

Service details

From the environmental impact point of view, that is air quality and global warming, LNG:

  • eliminates the SOx emissions
  • reduces the NOx emissions by almost 90%
  • reduces CO2 emissions significantly (by some 20% to 25%).

From the fuel cost impact, the use of LNG reduces the costs, in respect of Low Sulphur MGO.
Being an international regulatory framework not yet in place, a comprehensive set of technical rules from RINA is a good starting point for designers, owners and Flag Administrations.


The additional Class Notation is assigned upon participation in the development of the project, analysis of the layout and validation of the solutions adopted, approval of the equipment, systems, arrangement and procedures.


In the field of the LNG technology, we have followed the design of big regasification units, approved, surveyed during construction and classified the first off-shore FSRU.
Furthermore, we are actually involved in the classification of LNG fuelled ships and coordinate and/or partner in the development of various international research studies on the use of LNG as marine fuel
We are even acting as R/O in the process of acceptance of this not yet regulated fuel with flag Administrations.
