5. Conclusion

International and European regulations on the reduction of atmospheric emissions and greenhouse gases are leading to the use of LNG as a fuel to replace heavy fuel oil and diesel in maritime and inland waterway transport.

This transformation will extend over more than 20 years, and will require very high levels of investment to renew or adapt fleets, and to set up LNG supply networks in ports.

The availability of quality marine fuel oils meeting the sulphur content requirements of 0.10 and 0.50%m/m in 2020 remains problematic. LNG could therefore be the fuel for the energy transformation of maritime transport, subject to the resolution of a number of outstanding issues.

The use of LNG as a fuel significantly reduces emissions of SO _x , NO _x...
