CLEAN and CLEAN DESIGN
Voluntary Class Notations for Ships which are Designed, Built and
Operated in a way that Gives Additional Protection to the Environment
CLEAN and CLEAN DESIGN
CLEAN: Voluntary Class Notation for Deep Sea Transport Vessels which are Designed, Built and Operated in a way that Gives Additional Protection to the Environment
CLEAN and CLEAN DESIGN
CLEAN DESIGN: Voluntary Class Notation for Coastal and Passenger Vessels which are Designed, Built and Operated in a way that Gives Additional Protection to the Environment
CLEAN and CLEAN DESIGN
Typically CLEAN and CLEAN DESIGN cover: 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
CLEAN and CLEAN DESIGN
Common requirements
CLEAN and CLEAN DESIGN
ISM - To be implemented
ERS - Vessel included in ERS scheme by IACS memberBallast water management plan - To be implemented
Fuel oil management plan - To be implemented
Garbage management plan - To be implemented
CLEAN and CLEAN DESIGN
Common requirements
CLEAN and CLEAN DESIGNE0/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
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)
CLEAN and CLEAN DESIGN
Emissions to AIR cover the following systems and pollutants:
Incinerators
Propulsion SystemsNOx and SOx
Power Generation NOx and SOx
Cargo Evaporation
Fire Fighting
Refrigerants
CLEAN and CLEAN DESIGN
Emissions to AIR:
CLEAN and CLEAN DESIGN
Propulsion and Power Generation Systems
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)
NOx (Diesel engines):
CLEAN: Acc. to IMO NOx curve
CLEAN DESIGN: Acc. to IMO NOx curve, less 40%
CLEAN and CLEAN DESIGN
Emissions to AIR:
Incinerators
Refrigerants
All incinerators to be type approved in acc. with IMO MEPC.76(40). CLEAN DESIGN: Incinerator shall be installed
CLEAN: Ozone depleting not permitted, e.g.: CFC. (HCFC permitted until 2020.01.01)HFC and Natural refrigerants
CLEAN DESIGN: Natural refrigerants, only
CLEAN and CLEAN DESIGN
Emissions to AIR:
Fire Fighting
Cargo Evaporation
Vapour Emission Control (Tankers) according to IMO Standards for Vapour Emission Control Systems (MSC/Circ.585)
Limit on Global Warming Potential (GWP), more strict requirements for CLEAN DESIGN
CLEAN and CLEAN DESIGN
Discharges to SEA cover the following systems and pollutants:
Sewage System AntifoulingWaste and Garbage Management
Ballast Water
Bilge Water
Cargo and Cargo Residues
Fuel / Bunker 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

Discharges to SEA
Fuel/Bunker Oil
Cargo Oil

Discharges to SEA
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.

Discharges to SEASewage System
Waste and Garbage Management
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.
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.

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