Requirements for operators around air pollution
Overview of operator requirements to meet air protection rules
Different requirements apply depending on the size, age, and purpose of your ship.
Marine Protection Rules Part 199 is New Zealand’s legal basis for the requirements in Annex VI, Prevention of Air Pollution from Ships, of the International Convention for the Prevention of Pollution from Ships (MARPOL Annex VI).
View this short video to find out about environmental rules for commercial vessels.
For more information see below.
Changes to engine rules
As part of New Zealand’s commitment to MARPOL Annex VI, rules were introduced for engines over 130 kW on boats. These rules apply to New Zealand commercial vessels and recreational boats that do not visit overseas ports.
Guidance to help you comply
Maritime NZ has guidance to help ship operators identify which requirements apply to their ships.
Marine Protection Rules Part 199 Rules Guide
The Marine Protection Rules Part 199 Rules Guide includes:
- background on why New Zealand has signed up to MARPOL Annex VI
- the legal basis for Marine Protection Rules Part 199a description of each compliance requirements, grouped into these themes:
- fuel requirements
- nitrogen oxides (NOx) engine emissions requirements
- controlling other air pollutants
- carbon intensity reduction requirements for ships 400 GT or more
- reporting requirements for ships 5,000 GT or more
- suggested steps to help you achieve and maintain compliance
- instructions about when you must demonstrate each compliance requirement, and who is responsible.
Marine Protection Rules Part 199 Timeline Guide
The Marine Protection Rules Part 199 Timeline Guide is for commercial operators of New Zealand ships. It summarises the requirements from Marine Protection Rules Part 199, Prevention of Air Pollution from Ships, and when you must meet them.
You must read this guide together with the full text of the rules and the Part 199 Rules Guide. The Part 199 Rules Guide provides more detail about all the requirements and explains the terms used in the Part 199 Timeline Guide.
Marine Protection Rules Part 199 tool
You can use an optional questionnaire tool to see which requirements may apply to your ship. The tool provides an indication only. Ship operators are responsible for carefully checking all the requirements in Part 199 and identifying which requirements apply to their ship.
New environmental rules for domestic voyaging commercial vessels under 400 GT
This guide lists all of the requirements that apply to domestic voyaging commercial ships under 400 GT.
Operators of other commercial ships should use the main Part 199 Rules Guide.
Certification for ships 400 GT or more
If your ship voyages internationally, you need the following certificates to comply with MARPOL Annex VI and Marine Protection Rules Part 199. For domestic voyaging ships you can either hold these certificates or hold a MARPOL Annex VI endorsement on your Certificate of Survey.
International Energy Efficiency Certificate (IEE)
Maritime NZ or your recognised organisation issues the IEE. You only need this certificate to be issued once.
- Use the Part 199 vessel certificate application form below if:
- your ship is not in class, and
- you have had your ship surveyed, and
- you now need a certificate issued by Maritime NZ.
International Air Pollution Prevention Certificate (IAPP)
Maritime NZ or your recognised organisation issues the IAPP.
Use the Part 199 vessel certificate application form below if your ship is not in class, you have had your ship surveyed, and you now need a certificate issued by Maritime NZ.
IAPP Exemption Certificate (for unmanned non-self-propelled barges)
This certificate applies only to unmanned non-self-propelled barges. Maritime NZ or your recognised organisation must issue this certificate.
Engine certification
Engine International Air Pollution Prevention Certificate (EIAPP)
Maritime NZ or your recognised organisation must issue an EIAPP for all internationally voyaging ships with engines over 130 kW, or 174 HP.
Use the Part 199 vessel certificate application form below if you need Maritime NZ to issue an EIAPP for your engine. You need a valid EIAPP before you can apply for an IAPP.
For a MARPOL Annex VI endorsement, an EIAPP is one of the options you can use to show your engine complies.
Technical files
A technical file is required before an Engine International Air Pollution Prevention (EIAPP) Certificate can be issued. The technical file can relate to the specific engine, or to the parent engine of the engine family or group.
The NOx Technical Code 2008 (Technical Code)
defines a technical file as a record of all parameters, including components and settings of an engine, that may influence the engine’s NOx emissions.
Section 2.4 of the Technical Code sets minimum requirements for engine documentation to be accepted as a technical file. A technical file must include:
- identification of the components, settings, and operating values of the engine that influence its NOx emissions, including any NOx reducing device or system
- identification of the full range of allowable adjustments or alternatives for engine components
- a full record of the engine’s performance, including the engine’s rated speed and rated power
- a system of onboard NOx verification procedures to show compliance with NOx emission limits during onboard verification surveys in line with chapter 6
- a copy of the relevant parent engine test data, as set out in section 2 of appendix V of the Technical Code
- if relevant, the designation and restrictions for an engine that is part of an engine family or engine group
- specifications of spare parts and components that, when used in the engine in line with those specifications, mean the engine continues to comply with the NOx emission limit.
A technical file you submit with an application to Maritime NZ for an EIAPP must include this information. If the technical file does not include this information, Maritime NZ cannot consider the application and cannot issue an EIAPP for the engine.
Record book of engine parameters
Under Part 199, a record book of engine parameters is required when a technical file for a compliant engine says that the ‘engine parameter check method’ must be used to test compliance with NOx emission limits.
Some technical files include a section that you can use as a record book. If the technical file for your engine does not include this section, or you prefer to use a separate record book, you can use this template. You can amend the fields to reflect your engine’s specific components and settings.
The NOx Technical Code 2008 requires you to keep a record book of engine parameters to record all relevant changes to the engine. This includes like-for-like replacements and adjustments within approved ranges that you make to engine components and settings.
At survey, the surveyor will review the record book and technical file, along with the engine’s maintenance records and an inspection of the engine, to be satisfied that emissions are likely to be within Annex VI limits. See the timeline guide for Marine Protection Rules Part 199 for the dates when the Part 199 engine requirements are included in surveys.
Maritime NZ suggested practice: Even if engines do not need to be surveyed for compliance with Part 199 yet, we recommend that operators start using the record book now.
