Mumbai : Aniruddha Chaki, E&SS-cum-DDG (Tech.) Directorate General of Shipping, India has released a new notice for Implementation of MARPOL Annex VI: Consolidation of all DGS Order for Merchant Shipping on 14 November 2023. This is issued with the approval of the Director General of Shipping & Additional Secretary to the Government of India.

This 97 pages notice includes Circulars, Amendments and Forms with respect to MARPOL Annex VI. Such release of notice of Law is no new that is issued by DG Shipping. The fact that cannot be denied is who really follow it. When it comes to implementation, there is no stringent action taken by the authority like DG Shipping. The reason is lack of auditors. Neither the DG Shipping is having accurate number of vigilance officers nor they are giving contract for third party vigilance.

There are many local, national and international level organisations who have been demanding strict implementation of these Laws. But due to the lack of interest of the department and a said domination of companies on the department has paralyzed the system.

In such a scenario the whole sector is on ‘Ram Bharose’ ( On God’s Will ). India has always been ahead of signing big treatise. And gaining big names of bringing in new international laws.

But in reality when it comes to implementation, the department as well as the political leaders give it a blind eye and a big shake hand to the corporate.

However here are a few points for those who are really interested in knowing , understanding and learning…

A. Regulations :

1. Prevention of Air Pollution from Ships

2. Trials for Ship Emission Reduction and Control Technology Research

3. Emission from Seabed Mineral Activities

4. Unmanned Self-Propelled Barges

B. Certificates :

1. International Air Pollution Prevention Certificate

2. International Energy Efficiency Certificate

C. Major conversion

1.1 For the purpose of this regulation, major conversion means a modification on or after 1 January 2000 of a marine diesel engine that has not already been certified to the standards set forth in paragraph 3, 4, or 5.1.1 of this regulation where:

1. the engine is replaced by a marine diesel engine or an additional marine diesel engine is installed, or

2. any substantial modification, as defined in the revised NOx Technical Code 2008, is made to the engine, or

3. the maximum continuous rating of the engine is increased by more than 10% compared to the maximum continuous rating of the original certification of the engine.

1.2 For a major conversion involving the replacement of a marine diesel engine with a non-identical marine diesel engine, or the installation of an additional marine diesel engine, the standards in this regulation at the time of the replacement or addition of the engine shall apply. In the case of replacement engines only, if it is not possible for such a replacement engine to meet the standards set forth in paragraph 5.1.1 of this regulation (Tier III, as applicable), then that replacement engine shall meet the standards set forth in paragraph 4 of this regulation (Tier II), taking into account the guidelines developed by the Organization. 

1.3 A marine diesel engine referred to in paragraph 2.1.2 or 2.1.3 of this regulation shall meet the following standards:

1. for ships constructed prior to 1 January 2000, the standards set forth in paragraph 3 of this regulation shall apply; and

2. for ships constructed on or after 1 January 2000, the standards in force at

the time the ship was constructed shall apply.

Tier 1

3. Subject to regulation 3 of this Annex, the operation of a marine diesel engine that is

installed on a ship constructed on or after 1 January 2000 and prior to 1 January 2011 is

prohibited, except when the emission of nitrogen oxides (calculated as the total weighted emission of NO₂) from the engine is within the following limits, where n = rated engine speed (crankshaft revolutions per minute):

a. 17.0 g/kWh when n is less than 130 rpm;

b. 45-n(-0.2) g/kWh when n is 130 or more but less than 2,000 rpm;

c. 9.8 g/kWh when n is 2,000 rpm or more.

Tier II

4. Subject to regulation 3 of this Annex, the operation of a marine diesel engine that is installed on a ship constructed on or after 1 January 2011 is prohibited, except when the emission of nitrogen oxides (calculated as the total weighted emission of NO₂) from the engine is within the following limits, where n = rated engine speed (crankshaft revolutions per minute):

a. 14.4 g/kWh when n is less than 130 rpm;

b. 44-n(-0.2) g/kWh when n is 130 or more but less than 2,000 rpm;

c. 7.7 g/kWh when n is 2,000 rpm or more.

Tier III

5.1 Subject to regulation 3 of this Annex, in an emission control area designated for Tier III NOx control under paragraph 6 of this regulation (NOx Tier III emission control area), the operation of a marine diesel engine that is installed on a ship is prohibited:

1. except when the emission of nitrogen oxides (calculated as the total weighted emission of NO₂) from the engine is within the following limits, where n = rated engine speed (crankshaft revolutions per minute):

a. 3.4 g/kWh when n is less than 130 rpm;

b. 9. n(-0.2) g/kWh when n is 130 or more but less than 2,000 rpm;

c. 2.0 g/kWh when n is 2,000 rpm or more;

when

2. that ship is constructed on or after:

a. 1 January 2016 and is operating in the North American Emission Control Area or the United States Caribbean Sea Emission Control Area;

b. 1 January 2021 and is operating in the Baltic Sea Emission Control Area or the North Sea Emission Control Area;

3. that ship is operating in a NOx Tier III emission control area other than an emission control area described in paragraph 5.1.2 of this regulation, and is constructed on or after the date of adoption of such an emission control area, or a later date as may be specified in the amendment designating the NOx Tier III emission control area, whichever is later.
