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

CLEAN and CLEAN DESIGN

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.

CLEAN and CLEAN DESIGN

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.

CLEAN and CLEAN DESIGN

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
