Air emissions - SOX & PM

Monitoring of regulations

2.1 Implement a systematic control policy for documenting fuel (e.g., bunker delivery notes or any other proof of the control policy in place).

Note: Bunker notes must be conserved, and annual consumption notes must be kept for each ship.

2.2 Use climatology and weather forecasting to take advantage of tidal currents and avoid storms. Plan voyages to reduce running hours and idling time.

2.3 Optimize trim for fuel efficiency when loading ships and barges.

2.4 Follow voluntary slow speed measures in specific zones, as identified by port or governmental authority.

Note: the identified zones are Particularly Sensitive Sea Areas (PSSA): http://www.imo.org/en/OurWork/Environment/PSSAs/Pages/Default.aspx

2.5 Implement specific training for the relevant staff to maximize the benefits.

2.6 Identify optimal conditions of use and maintenance of the engines (including electronic injection, optimum speed, etc.) to minimize as much as possible SOx and PM emissions, as far as relevant engine information is available. On this basis, inform crew and ensure awareness of engine use and maintenance in these optimal conditions as far as possible.

2.7. Implement a replacement program for LED or other energy efficiency light upgrades.

Pilot boats and Tugs Only:

2.8. Reduce tug idling with dispatch scheduling and/or provide tie-up locations where awaiting tow or escort.

AND, fulfill one of the following 2 criteria:

4.2 Reduce SOx and PM emissions at berth by reducing emissions at each port of call by at least 95% when compared with the use of a fuel oil sulphured at 0.5%. These measures should be implemented on at least 25% of the fleet (representing 15% or more of the tonnage).

Note: For wet EGCS, the open loop system/mode must not be used.

OR

4.3 Reduce SOx and PM emissions at berth by using at each port of call, for powering at least all energy needs based on electricity on board, very low or zero-emission technologies or fuels, alternative fuel(s) or energies/energy vectors having low SOX and PM emissions, or certified EGCS or filtering technologies.  These measures should be implemented on at least 25% of the fleet (representing 15% or more of the tonnage).

Note: For wet EGCS, the open loop system/mode must not be used.

AND, fulfill one of the following 2 criteria:

4.4 Sample PM emissions for one of the fleet's main engine types (slow-speed, medium-speed, high-speed, gas or steam turbine).
Note: Sampling must be repeated every five (5) years. The sampling test plan must be consistent within the fleet, comparable with prior tests, and a recognized methodology, such as ISO 8178 or 40 CFR 51 Appendix M and 40 CFR 60 Appendix A.

4.5 Actively participate in research and development on reducing the impact of SOx and PM emissions, for example – improving inventory tools, developing hybrid or blended fuels, or conducting a pilot project on emission reduction technologies.

Note: Active participation is defined as the provision of support by the company, whether through financial means, human resources or equipment and can include an experimental shipboard trial.

5.1 The average sulphur content by mass of the total amount of fuel consumed annually by all of the company’s vessels is less than 0.2%.

3. using wind propulsion, or by;
4. using other energy-solutions that result in low SOx & PM emissions.

5.6 Each newbuild ship ordered by the company as of year 2024 or as of one year after the company’s initial certification, whichever comes first, permanently achieves the requirements for PM emissions (both in PM and PN) of Stage V limits for inland waterway vessels as provided by Regulation EU 2016/1628 on requirements for gaseous and particulate pollutant emission limits and type-approval for internal combustion engines for non-road mobile machinery, by applying an adapted technology such as diesel particulate filters (DPF), diesel oxidation catalysts (DOCs), electrostatic precipitators, etc. (a non-exhaustive list). Such a reduction must be certified in accordance with Regulation EU 2016/1628 and supported by relevant documentation.

Note: Class notations for ships already recognize compliance with the requirements of Stage V PM emission limits of Regulation EU 2016/1628, such as the ULEV notation by Bureau Veritas, or similar notation from any other IACS class society.
