To improve the knowledge within CCAMLR of vessels operating inside the Convention Area and recognising the need to control transhipment operations, CCAMLR requires Members to provide the details of vessel transhipments to the CCAMLR Secretariat at least 72 hours before transhipment is to occur. A vessel may also provide these details directly to the CCAMLR Secretariat. The required details include vessel information, the proposed time and position of transhipment and products to be transhipped. A List of transhipments is made available to Contracting Parties.
