LNG FUEL PROPULSION IN„RMDC” PROJECTS

GDAŃSK 2014

Why LNG?

Reasons:

� increasingly strict environmental regulations� increased pressure to use alternative fuel for transportation (goal of

reducing petroleum consumption); natural gas (NG) is a clear leader, offering benefits for the environment and energy security

� rising bunker oil prices� natural gas is cheaper – a price prognosis published by US Energy

Information Administration (EIA) shows that the disparity of prices between oil and gas fuels will systematically increase in coming 30 years(4,6% annualy); crude oil is predicted to reach a price three times higher than natural gas; it is also easily accessible

� natural gas technology and infrastructure is proven and available today (numerous new terminals are built or planed increases); the number of producing and importing countries has doubled in the past fifteen years, and industry experts anticipate that this growth will continue

Challenges:

�LNG tanks typically require 2 to 3 times more space than a diesel tank�since natural gas must be stored either liquefied or compressed, these storage tanks are also more expensive (the new-build cost of LNG-fulled ships is about 10-20% higher than for equivalent diesel-fulled ships)

Why LNG?

Classification society and Maritime Organizationsrequirements� IMO – Resolution MSC.285 (86) Interim Guidelines on Safety for Natural

Gas-Fuelled Engine Installations in Ships (adopted on 1 June 2009);

� IGF Code – IMO Draft - International Code of Safety for Ships Using Gases or Other Low Flashpoint Fuels;

� IGC Code – IMO – International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk;

� Classification Society Rules for Propulsion and Auxiliary Systems for Gas Fueled Ships;

� MARPOL 73/78 (International Convention on the Prevention of Pollution from Ships) Annex VI requirements

� Ferries and passenger vessels:• Ro-ro ferries• Ro-pax ferries

� Cargo carriers:• LNG/Ethylene/LPG Carrier

� Offshore vessels:• Platform supply vessels• Wind farm service vessels

LNG fuelled ships- LNG fuelled ferries

Vestfjord Project� The design comes in two versions: Inner and Outer. Basic difference is

the underwater body shape and the propulsion configuration.� The first two ferries (Landegode and Vaeroy) are destined basically for

the open sea route between Bodo and Lofoten islands, while the remaining two units (Baroy and Lodingen) are to operate between Tysfjord and Hinnoya island. The ferries are operating in difficult weather conditions beyond the polar circle.

Conclusions:

� LNG is an alternative available to Shipowners as they adept propulsion systems to comply with the strict IMO requirements governing ship emissions being introduced over the coming decade. Using LNG ensures that a ship will meet all planed emission restrictions, including the January 2016 Tier III nitrogen oxides (NOx) provisions, without the need any additional exhaust treatment systems.

� Although there is some resistance from owners due to concerns about fuelling infrastructure, the concept of LNG fuelling has gradually gained acceptance and it is now a question of “When?” rather than “If?”.

Conclusions:

� It is anticipated that within 10 years a considerable share at new ships will have natural gas filling, particularly in short-sea shipping

� It might also be expected that, in the coming years, some ships are retrofitted to run on LNG (converting existing vessels, especially services ships with short sailing distances, from diesel to gas engines).

� Norwegian owners are leading the implementation of gas-fuelled engines, especially for ferries.

� Canadian, German and Danish Shipowners also started to be interested in LNG propulsion.
