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 member
Ballast 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 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
CLEAN and CLEAN DESIGN
Covers 3 main areas of
environmental concern
пѓЁ
Air, operational emissions
пѓЁ
Sea, operational discharges
пѓЁ
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
Systems
NOx and SOx
Power
Generation
NOx and SOx
Cargo
Evaporation
Fire Fighting
Refrigerants
CLEAN and CLEAN DESIGN
Emissions to AIR:
Propulsion and
Power

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)
CLEAN and CLEAN DESIGN
Emissions to AIR:
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
CLEAN and CLEAN DESIGN
Emissions to AIR:
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)
CLEAN and CLEAN DESIGN
Discharges to SEA cover the following systems
and pollutants:
Ballast Water

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
Ballast Water
Antifouling
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:
