2 What I ll try to (briefly) tell you... Pubblicity: my Company! Why am I speaking of LNG (that) matters...? Our feasibility study (just a brief reference) Rules: what we used, where they are going Consequences of Rules changes not just for our designs! Building an LNG vessel: what about safety during construction phases?

11 What we used for the feasibility design: Some of the IACS Class Notations considered for the design: ABS : GUIDE FOR PROPULSION & AUXILIARY SYSTEMS FOR GAS FUELLED SHIPS BV : SAFETY RULES FOR GAS FUELLED INSTALLATIONS IN SHIPS DNV : GAS FUELLED ENGINE INSTALLATIONS GL : GUIDELINES FOR THE USE OF GAS AS FUEL FOR SHIPS LR : METHANE GAS FUELLED SHIPS RINA : GAS FUELLED SHIPS used for the design All of these Class Rules were (substantially) based onto the Resolution MSC.285(86): Interim Guidelines on Safety for Natural Gas-Fuelled Engine Installations in Ships

12 Rules requires distances of the LNG tanks from «ship s contour» Minimum distances of LNG tank from bottom and sides were required in the Interim Guidelines. These requirements are aimed to reduce risks of LNG spillage/release as a consequence of collisions

14 Consequences of introduction of this possible Rule Since 2000, between 40 and 50 LNG vessels were delivered, and a similar number of LNG newbuildings is presently under construction/on order. Hereunder is a brief summary about the consequences of this draft Rule for LNG tank length constraints. A large number of the delivered vessels/designs, particularly PSVs and Tugs (and some ferries, too), would be severly impaired by such a Rule.

15 Viking Energy Eidesvik: 2003 Loa = 95 m LNG -> 1 x 209 m3 Ltank = abt. 19 m (outer) L tank ~ 20% L ship

16 Bergensfjord Fjord 1: 2007 Loa = 130 m LNG -> 2 x 125 m3 Ltank = abt. 12 m (outer) L tank ~ 9% L ship

17 VIKING Grace VIKING LINES: 2013 Loa = 218 m LNG -> 2 x 200 m3 Ltank = abt. 19 m (outer) L tank ~ 9% L ship

18 Borgoy BUBE: 2014 Vertical Installation! Loa = 35 m LNG -> 1 x 86 m3 Dtank = abt. 3,5 4,5 m (outer) D tank ~ % L ship?

19 VS 4411 DF Siem Offshore Currently under construction, to be delivered within 2014 Loa = 90 m LNG -> 1 x 230 m3 Ltank = abt. 23 m (outer) L tank ~ 25% L ship

20 Gauthier Société des traversiers Québec Currently under construction, to be delivered within 2014 Loa = 133 m LNG -> 2 x 280 m3 Ltank = abt. 21 m (outer) L tank ~ 15% L ship

21 SV 310 DF Harvey Gulf Currently under construction, to be delivered within 2014 Loa = 92 m L tank ~ 23% L ship 1 week range! LNG -> 1 x 256 m3 Ltank = abt. 21 m (outer)

22 LNG Ferry Rosetti Marino Feasibility study Loa = 97 m LNG -> 2 x 50 m3 Ltank = abt. 6,2 m (outer) L tank ~ 6 % L ship

23 LNG Tug Rosetti Marino Feasibility study Loa = 35 m LNG -> 1 x 35 m3 Ltank = abt. 6,7 m (outer) L tank ~ 19 % L ship

24 42 LNG fuelled ships in operations 12 ships

25 39 Confirmed LNG fuelled Newbuilds 13 ships

26 Some consideration about this possible «tank length Rule» 1. Abt.30% of LNG fuelled vessels built until mid last year were PSVs 2. 30% of the ordered LNG fuelled newbuildings are PSVs/tugs 3. Large parte of the expected LNG fuelled newbuildings of the near future will be «short sea» ships; several of these are small size vessels 4. The proposed Rule, based onto results of collision risk evaluations among tankers and containerships, will severely impair range capability and feasibility of new (small) LNG fuelled vessels 5. If a tank length restriction has to be considered, it seems reasonable that an evaluation of the energetic content (i.e.: total amount of LNG content inside tank) could mitigate the Rule effect onto small size vessels

27 Safety during LNG newbuilding: some brainstorming/1 1. Risk Analysis to evaluate correct procedures for sequence of operations and shipbuilding completion 2. Dual Fuel or Single Fuel installation: different times are needed between engine start-up with NG and sea trials PRE-CHAMBER LINE MAIN LINE

28 Safety during LNG newbuilding: some brainstorming/2 3. First bunkering: to be planned as close as possible to sea trials. Safety procedures (e.g.: no use of cellular phones, only Safe Apparatus allowed, etc) within dangerous area 4. Safety survey on board after first bunkering (permanent watch) 5. Ship s Transfer inside Ravenna s Habour Area (3.5 miles) to be agreed with Local Port Authorities

29 Safety during LNG newbuilding: some brainstorming/3 6. After sea trials, LNG tanks to be emptied and filled with inert gas for ship s completion: facility service for receipt of unused LNG (e.g.: POLARGAS) availability of adequate quantity of N2 on call (useful also in case of emergency) 7. Final bunkering and final sea trial at ship s delivery 8. Procedures for emergency situations at quay or at sea (fire fighting procedures, specific equipment/training/qualifications) Our shipyard has the knowledge and is steadily preparing procedures to build LNG ships!
