5. CLEAN and CLEAN DESIGN Typically CLEAN and CLEAN DESIGNcover: CLEAN - Marpol Compliance with limited number of additional requirements CLEAN DESIGN -As for CLEAN, but with additional requirements, including design requirements for avoiding and limiting consequence of accidents

6. CLEAN and CLEAN DESIGN Common requirements CLEAN and CLEAN DESIGN ISM -To be implemented ERS -Vessel included in ERS scheme by IACS member Ballast water management plan - To be implemented Fuel oil management plan -To be implemented Garbage management plan -To be implemented

7. CLEAN and CLEAN DESIGN Common requirements CLEAN and CLEAN DESIGN E0/ECO - Technical requirements to be fulfilled Fuel oil - Added substances or chemical waste not permitted Antifouling -Limitation in use of TBT Double skin tankers -All tankers for oil to be arranged acc. to MARPOL 73/78, Annex I, reg. 13F

8. CLEAN and CLEAN DESIGN • Covers 3 main areas of • environmental concern • Air, operational emissions • Sea, operational discharges • Defensive Design, accident prevention and consequence limitation (Clean Design only)

9. CLEAN and CLEAN DESIGN Emissions toAIR cover the following systems and pollutants: Incinerators Cargo Evaporation Propulsion Systems NOx and SOx Fire Fighting Refrigerants Power Generation NOx and SOx

10. CLEAN and CLEAN DESIGN CLEAN and CLEAN DESIGN Emissions toAIR: Propulsion and Power Generation Systems NOx (Diesel engines): CLEAN: Acc. to IMO NOx curve CLEAN DESIGN: Acc. to IMO NOx curve, less 40% SOx (Diesel engines and boilers): General: CLEAN and CLEAN DESIGN: Max. sulphur in fuel oil onboard 3% (or 12.0 g SOx/kWh) In port and special areas: CLEAN: Max. sulphur in fuel oil 1.5% (or 6.0 g SOx/kWh) CLEAN DESIGN: Max. sulphur in fuel oil 0.5% (or 2.0 g SOx/kWh)

11. CLEAN and CLEAN DESIGN Emissions toAIR: Incinerators All incinerators to be type approved in acc. with IMO MEPC.76(40). CLEAN DESIGN: Incinerator shall be installed Refrigerants CLEAN: Ozone depleting not permitted, e.g.: CFC. (HCFC permitted until 2020.01.01)HFC and Natural refrigerants CLEAN DESIGN: Natural refrigerants, only

12. CLEAN and CLEAN DESIGN Emissions toAIR: Fire Fighting Limit on Global Warming Potential (GWP), more strict requirements for CLEAN DESIGN Cargo Evaporation Vapour Emission Control (Tankers) according to IMO Standards for Vapour Emission Control Systems (MSC/Circ.585)

13. CLEAN and CLEAN DESIGN Discharges toSEA cover the following systems and pollutants: Ballast Water Fuel / Bunker Oil Cargo and Cargo Residues Bilge Water Waste and Garbage Management Sewage System Antifouling

14. CLEAN and CLEAN DESIGN Discharges toSEA Fuel/Bunker Oil Cargo Oil General: CLEAN and CLEAN DESIGN:Drip/spill trays to be arranged with arrangements for draining. Requirement for spill tray applies also at vent. heads, etc. Minimum dimensions specified. CLEAN DESIGN:Drain from spill tray to be of closed type

15. CLEAN and CLEAN DESIGN Discharges toSEA Bilge Water CLEAN: 15 ppm alarm and automatic stopping device according to MARPOL 73/78, Annex I, reg. 16(2)(5) CLEAN DESIGN: As for CLEAN. In addition holding tank with facilities for delivery to shore.

16. CLEAN and CLEAN DESIGN Discharges toSEA Sewage System General:CLEAN and CLEAN DESIGN: Sewage treatment by comminuting/grinding and holding tank (MARPOL 73/78 Annex IV). CLEAN DESIGN: Grey water holding tank also for greywater on passenger ships and ferries. Waste and Garbage Management General:CLEAN and CLEAN DESIGN: Garbage management plan to be prepared and implemented. CLEAN DESIGN: Shall be equipped and arranged for sorting, minimising and storing garbage prior to incineration or delivery to shore.

17. CLEAN and CLEAN DESIGN Discharges toSEA Ballast Water Ballast water management to be implemented according to IMO res. A.868(20), Guidelines for the Control and Management of Ship’s Ballast Water to Minimise the Transfer of Harmful Organisms and Pathogens. Antifouling CLEAN: Non-TBT antifouling on ship’s flat bottom. Max. TBT leaching rate from antifouling on ship’s side : 4 μg TBT/cm2/day. No TBT after Jan. 1, 2003. CLEAN DESIGN: No TBT

18. CLEAN and CLEAN DESIGN Discharges toSEA Cargo residues CLEAN: Tanker for Oil: COW requirements Tanker for Chemicals: Max. remaining pollution cat. B: 0.1 m3 Max. remaining pollution cat. C: 0.3 m3 CLEAN DESIGN: Tanker for Oil: Stricter COW requirements Tanker for Chemicals: Max. remaining pollution cat. B and C: 0.05 m3

19. CLEAN and CLEAN DESIGN CLEAN DESIGN covers systems for accident prevention and consequence limitation such as: Nautical Equipment Redundancy Level Hull Subdivision Fuel Tank Arrgt.

20. CLEAN and CLEAN DESIGN CLEAN DESIGN Nautical Equipment Bridge design and layout complying to DNV Class Notation W1 Hull Subdivision Double skin giving protective location of all tanks with liquid cargo and fuel oil. Redundancy Level Alternate means for emergency propulsion “take me home device”
