Evergreen has placed strict controls on shipboard operations to reduce pollution to the sea, air and land. Ships' waste, discharge and emissions are closely monitored by shore-based staffs and standard operational procedures (S.O.P) are in place for SOx emission control, NOx emission control, ballast management, sewage management, garbage management, oil pollution prevention and leakage prevention of refrigerant (Freon).
In addition, we have installed state-of-the-art computer-based a weather routeing system developed by a professional weather consultant on our vessels to optimize our voyage plan in a timely manner and reduce CO2 emission. Every Evergreen Line vessel is equipped with the class-approved computer-based cargo loading system to adjust the trim, draft and hull strength, ensuring the ship's energy efficiency and safety at all times.
Shipboard data, such as oil consumption rate, voyage condition, tank condition and loading condition and other data can be transferred through satellite communications to the office for analysis on a daily basis.
We also have reduced our vessel speed and carry minimum ballast water onboard to reduce the fuel consumption and improve energy efficiency.
CO2 Emission Control
Evergreen is reducing CO2 emission by rationalizing our port rotation to enable vessels sailing with lower engine output and reduced fuel consumption. We are also starting the slow steaming project that will shut down one turbo charger to reduce the main engine output by 33%. According to the engine maker's calculation, reducing this output will also significantly cut the CO2 emission rate on the same trade routes. Each vessel, including chartered vessels in Evergreen Line's fleet, now have installed computer-based weather routing system provided by our weather news consultant. This allows the captain to select the most efficient and shortest distance to avoid bad weather at sea. Our vessels are also turning off unnecessary electric power in lighting and pumps to minimize the number of generators running onboard in an effort to reduce CO2 emission.
SOx Emission Control
- Evergreen is using MGO which contains less than 0.1% m/m sulphur at berth in EU port on JAN/01/2010.
- The sulphur content of any fuel oil used on board ships shall not exceed 3.5% m/m (by weight). Date of entering into force: JAN/01/2012.
- Evergreen is using MGO which contains less than 0.1％ m/m sulphur within 24 nautical miles from closest California shoreline on Jan/01/2014.
- The SECA (North Sea, English Channel, Baltic and North American) 1.0% m/m limit that would take effect from Jan/01/2015.
- Evergreen is using marine fuel which contains less than 0.5％ m/m sulphur at berth in Hong Kong port on Jul/01/2015.
- Evergreen is using Light（distillate）fuel when transiting Panama Canal on Apr/19/2017.
- On January 1, 2019, emission control areas in the China's territorial waters and the international commercial port area of the Republic of China(Taiwan) were mandated to using fuel oil with sulfur content < 0.5% m / m.
- Navigate with economic speed as practicable
- Carry minimum ballast water on board
- Keep proper trim
NOx Emission Control
- For new buildings, Evergreen will install a main engine with a lower NOx emission main engine.
- If any adjustments, parts/components replacements and modifications are carried out that influence NOx emission, these shall be verified to comply with the shipboard Technical File. They shall also be recorded chronologically in an engine's record book of engine parameters for on-board verification for control of NOx emission or equivalent record-keeping. The engine's record book is used for parameters check of on-board NOx verification and this record may be checked by Government Officials.
- Ordering spare parts must be done with the ID-number that was specified on the shipboard Technical File.
- The correct ID-number must be checked when parts are to be received onboard ship.
- Record the substitute parts information in the engine's record book of engine parameters for onboard verification to ensure control of NOx emission or equivalent record that included component specifications (ID-number), date of replacement, cylinder number (if necessary) and signed by the Chief Engineer.
- Navigate with the most efficient and economical speed as practicable
- Carry minimum ballast water onboard
- Keep proper trim
Ballast Water Exchange Practices
- Evergreen has established a "Ballast Water Management Plan" that is applied to all vessels in our fleet for conducting ballast water exchange onboard. or
- Using Ballast Water Treatment Plant Evergreen L-Type vessel will install the ballast water treatment plant which is fully apply the IMO guideline to ensure the ballast water exchange during ship operation not to cause such problem and lower the environment impact.
To comply with the International Convention on the Control of Harmful Anti-fouling Systems on Ships, Evergreen started utilizing "Tin-free" paint for ship's hull coating in June 1999. As of the end of 2002 all our vessels were using "Tin-free" paint for ship's hull coatings.
Evergreen also commenced testing trials of using "Silicon-based" paint for ship's hull coatings in March 2007.
A "Garbage Management Plan" in compliance with Annex V of MARPOL 73/78 for the Evergreen Line fleet was instituted to deal with all types of garbage generated on board including hazardous and solid waste.
Garbage management is divided into five processes: Collection, Processing, Storage, Disposal and Record.
Garbage collection points on board are set up in specific locations including the ship's gangway station, upper deck, galley, mess room, engine room, wheelhouse, accommodation spaces and central reception areas.
All garbage is classified into five categories:
- Plastics and plastics mixed with non-plastic garbage;
- Food waste;
- Oil contaminated and flammable garbage;
- Hazardous and solid wastes including medical waste, chemical drum, paint drum, used batteries and fluorescent lamps;
Policy for handling categories of garbage:
Plastics and plastics mixed with non-plastic garbage
Disposal at sea is prohibited. Plastic garbage must be retained on board the ship for discharge at port receptacle facilities. A receipt or certificate specifying the estimated amount of garbage transferred must be obtained from the operator of the port facilities or from the master of the ship transferring the garbage. The receipt or certificates must be kept on board the ship with the Garbage Record Book for three years.
Food waste can only be disposed at sea in the area outside of 25 nautical miles off shore. This waste shall be retained onboard inside a refrigerator for food waste when the vessel is within the 25 nautical miles off shore and while in port.
Oil contaminated and flammable garbage
Oily and/ or contaminated rags must be kept onboard and discharged to port receptacle facilities or incinerated.
Hazardous solid wastes
Such waste should be kept separate from other garbage and preferably treated as recycling materials and retained for disposal in port.
- Other garbage can be disposed of at sea only when the vessel is 25 nautical miles off shore.
All Evergreen Line vessels are equipped with a garbage compressor to reduce the volume.
Although Annex V of MARPOL 73/78 permits some categories of garbage to be disposed at sea, Evergreen encourages its ships to discharge garbage to qualified shore facilities.
Sludge is residue of the fuel oil. All sludge produced by our fleet is carefully collected, measured, monitored and discharged at port facilities. A receipt or certificate specifying the amount of sludge transferred must be obtained from the operator of the port facilities or from the master of the ship transferring the sludge. The receipt or certificates must be kept on board the ship with the Oil Record Book for three years.
In general, the use of shipboard garbage incinerators in ports or near urban areas should be discouraged as their use will add to possible air pollution in these areas. In order to reduce air pollution, the entire Evergreen Line fleet has been directed to minimize usage of the shipboard incinerator. This helps reducing production of incinerated ashes and also CO2. Ashes produced by the shipboard incinerator should only be discharged to the port reception facilities. Plastic garbage must be retained on board for discharge at port facilities unless reduced to ashes without toxic or heavy metal residues by a type-approval incinerator.
Safe Ship Operations
Our safety management system is based on ISM code and is part of Evergreen's SQE management system. The safety measurement indicators used to evaluate safety performance of our fleet include frequency of collision, grounding and containers fallen overboard and LTAF (Lost Time Accident Frequency).
For achievement of safety goals and prevention of incident recurrence, our crews take the following countermeasures:
- Enhance on board inspection conducted by managers of marine department and maintain consistent internal audit.
Heat insulation of new reefer containers will be reinforced. The Evergreen Line fleet is also enhancing the cleaning of heat-exchangers for existing reefer containers.
Container waste generated onboard, particularly dangerous cargo waste, are collected in a salvage drum and discharged to shore qualified facilities.
