Monitoring of regulations.
Implementation of 6 of the following 9 best practices on all company ships:
2.1. Ensure performance of each oily water separator (OWS) by:
2.2. Periodically test oil content alarm prior to operating the oily water separator and in any case at least once a month if the equipment is not used.
2.3. Use seals or locks on all overboard discharge valves.
2.4. Post signs in the vicinity to clearly indicate who is responsible for opening any of the OWS overboard discharge valves, for operating oily water separation equipment and for oil transfer procedures.
2.5. Lock out or seal the oil content meter so that the calibration cannot be tampered with.
2.6. Maintain proper coordination with the navigation bridge when opening the overboard discharge valve so a designated officer can also record the activity and the vessel’s position.
2.7. When feasible, only operate the oily water separator during the daytime.
2.8. Regularly clean the applicable bilges and remove any solid material that may reduce the performance of the OWS.
2.9. Reduce as much as possible the use of emulsifying cleaners and agents that can degrade the performance of the OWS.

Implementation of 5 of the following 9 best practices on all company’s ships:
2.10. Regularly inspect and perform preventative maintenance of equipment using oil (an engine, burners, pumps, heaters, filters, etc.) or water (condensers, boilers, pumps, etc.) to prevent leaks.
Note: Inspections should be done at least in line with manufacturers recommendations.
2.11. Regularly inspect and maintain stern tube seals and bearings to prevent water from entering.
Note: Inspections should be done at least annually.
2.12. Stop leaks of oil or water in the engine room as soon as possible.
2.13. Clean up oil and water spills as soon as possible after maintenance and repair operations.

Note: inspections should be done at least annually.
2.15. Regularly clean bilges and remove any solid material.
Note: Inspections should be done at least annually.
2.16. Post signs in the vicinity to clearly indicate who is responsible for bilge water transfer procedures.
2.17. Give staff proper training on bilge water transfer procedures.
2.18. Keep available on board oil absorption pads to intervene in case of minor oil spills.
3.1. Adopt an Oily Water Management plan that formally incorporates all the best practices itemized in level 2.
Note: See Annex 4-A.
3.2. Complete an inventory of treated bilge water and sludge.
Note: See Annex 4-B.
3.3. Develop and adhere to environmental procurement guideline for cleaning products to be used within the engine room, considering third party certifications* and product content**
*Such as Centre for Environment, Fisheries and Aquaculture Science (Cefas).
**Chlorine, phosphate free, minimally toxic, etc.
3.1. Adopt an Oily Water Management plan that formally incorporates all the best practices itemized in level 2.
Note: See Annex 4-A.
3.2. Complete an annual inventory of bilge water (produced, treated, discharged to sea, and off-loaded to shore, as applicable) and of oil residue (sludge) on a vessel by vessel basis and for the fleet as a whole.
Note: See Annex 4-B.
3.3. Develop and adhere to environmental procurement guideline for cleaning products to be used within the engine room, considering third party certifications* and product content**
*Such as Centre for Environment, Fisheries and Aquaculture Science (Cefas).
**Chlorine, phosphate free, minimally toxic, etc.
4.1. Adopt a modernization policy for oily water separators and all related control and verification equipment. Systematic application of this policy on all new buildings and all ships undergoing major modifications.
Note: See Annex 4-C.
Implementation on at least one ship in the company’s fleet:
Vessels built after January 1st, 2011:
4.2. Implement of an integrated bilge treatment system such as that defined in the IMO’s revised guidelines (MEPC.1/Circ.642, 12 November 2008).
OR
Vessels built before 2011:
4.3. Demonstrate of an integrated bilge treatment system approach by respecting the requirements defined in Annex 4-D.
Note: See Annex 4-D.
4.1. Set reduction targets (for the fleet as a whole or by vessel category) for bilge water produced.
4.2. Implement effective measures to reduce the quantity of bilge water and sludge produced on 50 % of the company’s vessels targeted for reduction.
Examples: Separate drainage systems for water and oil drains, installation of drip trays or coamings under equipment, use less water for maintenance and cleaning, replacement and repair of stern tube seals, etc.).
