8 Rules and regulations for transportation of gases and low flashpoint liquids International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk. The IGC Code International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk. The IBC Code

9 Existing Rules & regulations for low flash point fuels. IMO Res MSC.285(86). INTERIM GUIDELINES ON SAFETY FOR NATURAL GAS-FUELLED ENGINE INSTALLATIONS IN SHIPS. The IGF-Code. Adresses only natural gas as fuel. LR. Rules and Regulations for the Classification of Natural Gas Fuelled Ships. Adresses natural gas and natural gas in combination with oil. DNV. Gas Fuelled Ship Installations. Adresses natural gas as fuel and gives opening for other fuels after special consideration. Other Class Societies Rules.

10 The DRAFT INTERNATIONAL CODE OF SAFETY FOR SHIPS USING GASES OR OTHER LOW FLASH POINT FUELS (IGF CODE). Under development. Intended fuels: Natural Gas (LNG) CH4 IGF Code Part A-1 Propane C3H8 Butane (i and n) C4H10 Propane/Butane mixtures Ethyl alcohol C2H5OH IGF Code Part A-2 Methyl alcohol CH3OH IGF Code Part A-2 Hydrogen H2 Dimethyl-ether CH3OCH3

14 LNG Fuelled vessels. Newbuildings. LNG-carriers. Long and excellent experience. Glutra. Jan Now Around 100 existing ships and confirmed orders.

15 Conversion from HFO to LNG. BIT VIKING. 2 x 500 m3 cryogenic tanks on deck

16 VIKING GRACE LR Rules Gas storage tanks are to be located on the open deck or, where not practicable, in enclosed or semi-enclosed spaces.

23 LNG Feeder Tanker for Liquefied Gas

24 LNG Bunkering barge. Tanker for Liquefied gas

25 Methanol can be stored in tanks similar to tanks for petroleum products.

26 Methanol tank at Perstorp ton per year

27 Tanker for Oil and Chemicals

28 Bunker vessel oil & methanol Tanker for Oil and Chemicals

29 Ships other than chemical carriers - transporting methanol DNV Pt 5 Sec 8 B 102. Where not bound by bottom shell plating or pump room, the tanks shall be surrounded by cofferdams.

30 Double walled High pressure fuel pipes Ballast tank converted to methanol fuel tank High pressure pump room Transfer pump room

31 Methanol in integral tanks and service tank on deck

32 Fuel storage onboard and ashore. LNG storage require complex and expensive fuel containment systems. Methyl alcohol is far less complicated to store.

40 Summary Methanol is a clean low flash point fuel fullfilling upcoming requirements. The methanol fuel containment system onbord and the infra structure ashore are considerably less expensive than for LNG Rules and regulations exist to a large extent and are under further development. In many parts similar requirements as for LNG. There is no doubt we can handle safety issues re methanol onbord used for fuel The existing methanol industry can coop with an increase in demand of 20 mill ton.
