The function of the Regional Coordination of Operations Centre (RCOC) in Seychelles includes several key responsibilities aimed at enhancing maritime security in the Western Indian Ocean. These responsibilities are aligned with the objectives of the Maritime Security in Eastern & Southern Africa & Indian Ocean (MASE) programme. The specific mandates of the RCOC are as follows:

1. Conducting Joint Maritime Operations: The primary function of the RCOC is to coordinate and conduct joint maritime operations among the signatory countries to ensure a cohesive and effective response to maritime security threats.
2. Coordination with RMIFC: The RCOC works closely with the Regional Maritime Information Fusion Centre (RMIFC) based in Madagascar. The RMIFC is responsible for gathering and disseminating maritime information, and the RCOC acts on this information to address abnormal or suspicious activities at sea.
3. Collaboration with National Centres: The RCOC maintains continuous communication and coordination with our National Information Sharing Coordination Centre (NISCC) and national maritime security centres in the seven signatory countries (Comoros, Djibouti, France/Réunion, Kenya, Madagascar, Mauritius, and Seychelles). This collaboration ensures a unified approach to maritime security across the region.
4. International Liaison Officers: The RCOC hosts International Liaison Officers (ILOs) nominated by each of the signatory states. These officers facilitate international cooperation, information sharing, and operational coordination.
5. Operational and Administrative Support: The RCOC benefits from the operational and administrative support of the Seychelles government, specifically under the Ministry of Internal Affairs. This support includes resources and logistical backing necessary for the centre's effective functioning.
6. Implementation of MASE Agreements: The RCOC is responsible for implementing the provisions of the two MASE agreements related to the exchange and sharing of maritime information and the coordination of joint actions at sea. These agreements were established to enhance regional maritime security and cooperation.

Through these functions, the RCOC plays a critical role in ensuring maritime safety and security in the Western Indian Ocean, fostering regional cooperation, and responding effectively to maritime threats and incidents.
