The use of liquefied natural gas (LNG) as fuel for propulsion of commercial ships can lead to both the significant reduction of the ship engines exhaust gas emissions (CO2, NOx, SOx, PM), and the lower operational cost due to the substantial lower price of LNG (compared to the Diesel fuels). Thus, LNG fueled ships are expected to dominate in medium to long-term due to the rising of fuel prices, the tightening of legislation concerning the ship energy indices (EEDI, EEOI) and gaseous emissions and the discovery and extraction of new gas sources worldwide.
The present project deals with the conversion of existing shuttle ferries and containerships in order for their diesel propulsion plants to operate on either LNG fuel, Diesel fuel or combined LNG-Diesel fuel. The study will include the modifications on the ship propulsion installation, the auxiliary systems and machinery required for the storage and use of liquefied natural gas as fuel for ships, the additional requirements for the ship safety systems, the regulations required at national and international level for the operation of ships with fuel LNG, the land based installations and the means for LNG bunkering and cost-environmental impact assessment of the proposed conversion.
Open type ferries are extensively used for short distance routes throughout the Greek territory, and especially close to urban areas, so the use of LNG as fuel will have multiple benefits for the maritime companies, the natural environment conservation and the Greek economy. On the other hand, the Chinese side partners, due to their involvement in the shipbuilding activities, are interested in gaining experience in the design of LNG fueled containerships.
