1. How will the regulation work? How to follow up the regulation?
International Maritime Organisation MARPOL 73/78 Annex VI REGULATION FOR THE PREVENTION OF AIR POLLUTION FROM SHIPS
What will be regulated?
How will the regulation work?
How to follow up the regulation?

2. What will be regulated? OZONE DEPLETING SUBSTANCES
Emissions of ozone depleting substances are prohibited Deliberate emissions of new installations with ozone depleting substances are prohibited after entry into force. Exemptions is made for new installations containing HCFC, which are permitted until 1 January 2020
NITROGEN OXIDES
Diesel engines with power output or more than 130 kW shall comply with the NOx-code when installed in a vessel on or after 1 January 2000

3. SULPHUR-OXIDES
The sulphur content of any fuel oil shall not exceed 4.5% - possibility for limited emissions for vessels operating in a SOx Emission Control Area
VOLATILE ORGANIC COMPOUNDS
Procedures on how to regulate Volatile Organic Compounds (VOC) emissions in port- and terminal areas

4. Requirements to fuel oil quality
INCINERATORS
Incinerators installed after 1 January 2000 shall meet the requirements of the revised resolution MEPC.59(33)
RECEPTION FACILITIES
The liabilities in connection with establishment of onshore reception facilities for ozone depleting substances and exhaust gas cleaning residues from ships will be concretised
FUEL OIL QUALITY
Requirements to fuel oil quality
The requirements will also apply to fixed and floating platforms and drilling rigs

5. How will the regulation work?
Emission Requirement for Nitrogen Oxides (NOx)
The permissible emission is a function of the engines rpm and varies from 17.0 g/kWh when the rated engine speed is less than 130 rpm, to 9.8 g/kWh when the engine speed is equal to or above 2000 rpm.

6. Emission Requirement for Nitrogen Oxides (NOx) (Cont.)
Permissible emission levels are given as weighted average values for specific emissions over the engine load range
Allowable emission levels are calculated and how actual levels are to be controlled for an engine is specified in “Technical Code in Control of Emission of Nitrogen Oxides from Marine Diesel Engine
This code is mandatory

7. Emission Requirement for Sulphur Oxides (SOX)
A bunker delivery note and a representative sample from each bunkering will be mandatory upon entry into force of the Protocol
For Baltic Sea area and any other sea area designated by the Organisation in accordance with criteria and, procedures for designation of SOx Emission Control Areas, the sulphur content in oil used on board ships shall not exceed 1.5% or 6.0 g SOx/kWh

8. How to follow up the regulation?
Certificates
Ships of 400 gross tonnage and above and rigs engaged in voyages in international waters are required to document compliance with this Annex by having an International Air Pollution Prevention (IAPP) Certificate approved by the flag state
Engines complying with the NOx Code will be issued an Engine International Air Pollution Prevention (EIAPP) Certificate

9. To ensure follow-up of regulation:
Type approval of engines on test-bed
Inspections and surveys (for ships of 400 gross tonnes and above and rigs and platforms)
IAPP-Certificate
“Initial Survey” before operating (and issue of certificate)
“Periodical Surveys” (at least every 5 years, according to regulations of the authorities)
At least one “Intermediate Survey” within a 5 year period
The regulations will give specific guidelines to type approval, how to conduct surveys, and how to react upon any non-compliance

10. ENTRY INTO FORCE
ANNEX VI is now ready to be ratified by the individual States who have membership in IMO
ANNEX VI shall enter into force twelve months after the date on which not less than fifteen States, the combined merchant fleets of which constitute not less than 50 per cent of the gross tonne of the world’s merchant shipping, have become Parties to it in accordance with article 5 of the present protocol
If ANNEX VI is not given required support within the end of year 2000, IMO is obligated to re-evaluate the ratification process for the regulation
