MARPOL Annex V
Summary
Seafarers in the past unknowingly harmed the environment by throwing garbage overboard, which led to contamination of seas, harm to wildlife, and beach littering. Marpol Annex 5, enacted in 1988, aims to regulate the disposal of plastics at sea and promote sustainable waste management practices. Ships are now required to keep all garbage on board, follow strict disposal guidelines, and maintain a detailed garbage management plan to minimize waste and ensure compliance with regulations to protect the marine environment.
Introduction to Ocean Pollution
Seafarers in the past used to believe that throwing garbage overboard caused no harm, but the reality is that it contaminates the seas, harms wildlife and plants, and litters beaches. Various substances like painted wood and plastic take many years to biodegrade, with some types of plastic estimated to last for centuries. Millions of tons of plastic enter the oceans annually, impacting marine organisms and the food chain. Marine debris not only affects the environment but also has economic repercussions, costing billions of dollars each year in the Asia-Pacific region alone.
History of Marpol Annex 5
Marpol Annex 5, entered into force in 1988, regulates the prevention and banning of disposal of plastic at sea. The regulations were amended in 1998 to focus more on sustainable waste management and record-keeping. Further revisions in 2011 completely restricted the discharge of all forms of garbage at sea, except for specific exceptions like food waste, animal carcasses, non-harmful cargo residues, and cleaning agents. Ships are now required to keep all garbage on board, including plastics and harmful cargo residues, and follow strict disposal guidelines.
Garbage Management Strategies
Ships of 100 gross tons upwards and those certified to carry 15 or more persons must have a garbage management plan based on IMO guidelines. The plan should detail procedures for garbage handling, crew responsibilities, and best practices for shipboard garbage management. The key focus is on minimizing garbage by avoiding disposable items, using reusable or recyclable packaging, and employing efficient storage and handling methods. The plan must be implemented by designated personnel, such as environmental control officers, and training is critical for ensuring compliance.
Garbage Collection and Processing
Proper garbage collection involves separating different types of waste and maintaining a garbage record book. The book categorizes garbage items such as plastics, food waste, incinerator ashes, and operational wastes. Food waste and hazardous materials should be stored securely to prevent risks. Garbage processing methods like compaction, grinding, and incineration help reduce volume and facilitate discharge in port. Following manufacturer instructions is crucial for safe and effective processing.
Discharge Regulations and Special Areas
Strict discharge regulations apply, with restrictions on the types of garbage that can be discharged into the sea, especially in special areas like the Mediterranean Sea, Baltic Sea, and polar waters. Ships must adhere to specified distances from land for discharge and follow guidelines for different types of waste. Offshore platforms and ships near these platforms also face restrictions on garbage disposal. The discharge of harmful substances and solid bulk cargo residues into the sea is prohibited in special areas.
Garbage Record Keeping and Compliance
Ships covered by Marpol Annex 5 must maintain a garbage record book with detailed entries on garbage disposal activities, incineration, and accidental losses. Officers responsible for entries should be trained in record-keeping procedures. Compliance with garbage disposal regulations is crucial, as violations can lead to fines and legal actions. The revised Annex 5 emphasizes the proper management of shipboard garbage and the importance of minimizing waste for environmental protection.
