THOSE COUNTRIES, ARE REQUIRED TO HAVE AN
INTERNATIONAL AIR POLLUTION PREVENTION CERTIFICATE
(IAPP CERTIFICATE). 
 
THE IAPP CERTIFICATE WILL BE ISSUED FOLLOWING AN INITIAL
SURVEY CARRIED OUT BY THE FLAG ADMINISTRATION OR BY
THE CLASS (E.G. DNV, CLASSNK) ON BEHALF OF THE FLAG
ADMINISTRATION, CONFIRMING COMPLIANCE WITH MARPOL
ANNEX VI. FOR SHIPS WITH THE FLAG OF AN ADMINISTRATION
THAT HAVE NOT YET RATIFIED ANNEX VI, A CERTIFICATE OF
COMPLIANCE WITH ANNEX VI ISSUED BY THE CLASS.

ANNEX VI ALSO REQUIRES DIESEL ENGINES (AS DESCRIBED ABOVE)
TO CARRY INDIVIDUAL CERTIFICATES WITH REGARD TO NOX
EMISSIONS, NAMED ENGINE INTERNATIONAL AIR POLLUTION
PREVENTION (EIAPP) CERTIFICATES.  
ANNEX VI REQUIRES THAT EVERY SHIP OF 400 GROSS TONNAGE OR

REGULATION 14 - SULPHUR OXIDE (SOX) !
!
EMISSIONS FROM SHIPS  
- 19 MAY 2005 ANNEX VI TO MARPOL ENTERED INTO !
!
FORCE.  
- THE REVISED ANNEX VI TO MARPOL WAS ADOPTED BY !
!
IMO ON 10 OCTOBER 2008.  
 
THE SULPHUR OXIDE (SOX) AND PARTICULATE MATTER !
!
EMISSIONS FROM SHIPS WILL IN GENERAL BE CONTROLLED !
!
BY SETTING A LIMIT ON THE SULPHUR CONTENT OF MARINE FUEL !
!
OILS AS FOLLOWS. THE SULPHUR CONTENT OF ANY FUEL OIL USED !
!
ON BOARD SHIPS SHALL NOT EXCEED THE FOLLOWING LIMITS:

Outside an ECA established
to limit SOx and particulate
matter emissions
Inside an ECA established to
limit SOx and particulate
matter emissions
4.50% m/m prior to 1
January 2012
1.50% m/m prior to 1 July
2010
3.50% m/m on and after 1
January 2012
July 2010
January 2020*
January 2015
22

23
❑THE ECA ESTABLISHED ARE: 
❑I. BALTIC SEA AREA – AS DEFINED IN ANNEX I OF MARPOL (SOX
ONLY); 
❑II. NORTH SEA AREA – AS DEFINED IN ANNEX V OF MARPOL
(SOX ONLY); 
❑III. NORTH AMERICAN AREA (ENTERED INTO EFFECT 1 AUGUST
2012) – AS DEFINED IN APPENDIX VII OF ANNEX VI OF MARPOL
(SOX, NOX AND PM); AND 
❑IV. UNITED STATES CARIBBEAN SEA AREA (EXPECTED TO
ENTER INTO EFFECT 1 JANUARY 2014) – AS DEFINED IN
APPENDIX VII OF ANNEX VI OF MARPOL (SOX, NOX AND PM).

24

25
MOST SHIPS WHICH OPERATE BOTH OUTSIDE AND INSIDE THESE
ECA WILL THEREFORE OPERATE ON DIFFERENT FUEL OILS IN ORDER TO
COMPLY WITH THE RESPECTIVE LIMITS. !
!
IN SUCH CASES, PRIOR TO ENTRY INTO THE ECA, IT IS
REQUIRED TO HAVE FULLY CHANGED-OVER TO USING THE ECA
COMPLIANT FUEL OIL, REGULATION 14.6, AND TO HAVE ONBOARD
IMPLEMENTED WRITTEN PROCEDURES AS TO HOW THIS IS TO BE
UNDERTAKEN. !
!
SIMILARLY CHANGE-OVER FROM USING THE ECA COMPLIANT
FUEL OIL IS NOT TO COMMENCE UNTIL AFTER EXITING THE ECA. AT EACH
CHANGE-OVER IT IS REQUIRED THAT THE QUANTITIES OF THE ECA
COMPLIANT FUEL OILS ONBOARD ARE RECORDED, TOGETHER WITH THE
DATE, TIME AND POSITION OF THE SHIP WHEN EITHER COMPLETING THE
CHANGE-OVER PRIOR TO ENTRY OR COMMENCING CHANGE-OVER
AFTER EXIT FROM SUCH AREAS. !
!
THESE RECORDS ARE TO BE MADE IN A LOGBOOK AS
PRESCRIBED BY THE SHIP’S FLAG STATE, IN THE ABSENCE OF ANY
SPECIFIC REQUIREMENT IN THIS REGARD THE RECORD COULD BE
MADE, FOR EXAMPLE, IN THE SHIP’S ANNEX I OIL RECORD BOOK.

26
SOX CONTROL:  
- ARRANGEMENTS FOR LSFO & HSFO: 2 0R !
!
MORE DIFFERENT TYPES OF FUELS. 
- AVAILABILITY –BUNKING STRATEGIES 
 
- SWITCH-OVER(12 TO 24 HRS) WILL NEED TO !
!
BE CHANGED OVER THE FUEL FOR THE SECA !
!
PASSAGES. 
 
- HANDLING OF CYLINDER OILS –2 QUALITIES MAY !
!
BE REQUIRED. 
 
- MORE STRICT FOLLOW UP THROUGH SAMPLE !
!
REQUIREMENTS, AND CONTROL OF DOCUMENTATION !
!
AND PROCEDURE TO LOG DOWN.

27

28
OTHER METHODS FOR CONTROLLING OF NOX AND SOX: 
- EXHAUST GAS CLEANING SYSTEM OR OTHER EQUIVALENT SYSTEM: MAY BE USED
(ABATEMENT TECHNOLOGIES). THE EMISSION CRITERIA FOR SUCH SYSTEMS ARE 6 G SOX/
KWH. 
- RELIFIQUATION PLANTS FOR LNG/LPG CARRIERS: REDUCTION OF NOX, SOX & COST
SAVING THROUGH BOILED OFF GAS REUSE. 
- ALFA LUBRICATOR SYSTEM: REDUCTION IN CYLINDER OIL CONSUMPTION. REDUCTION IN
PARTICULATE EMISSION. 
- ELECTRONIC CONTROL ENGINE : PROGRAMMED FUEL INJECTION AND EXHAUST VALVE.
REDUCE FUEL & REDUCTION OF EMISSION.  
- TURBO GENERATOR PLANT: USE OF HIGH EFFICIENCY AIR FLOW FOR POWER TAKE OFF.
REDUCE FUEL & REDUCTION OF EMISSION. 
- SYSTEM INTEGRATION: HUMID AIR MOTOR (HAM)- ENGINE INTAKE AIR OPERATING WITH
WATER & EXHAUST GAS RECIRCULATION (EGR). 50% REDUCTION OF EMISSION. 
- HFO SULFUR CONTENT – USE OF LOW SULFUR OIL AND MODIFY THE EQUIPMENTS TO
BURN LSFO. 
- DUAL FUEL OPTION FOR LOW SULPHUR RESTRICTED AREAS: NEED FOR ADDITIONAL TANKS
AND DUAL FUEL ENGINES.
