At present, we operate a Central Monitoring and Control System (CMCS), which is centrally monitored 24/7 by our Operations and Planning Centre based in Harwich. This system enables the monitoring and remote operation of marine Aids to Navigation (AtoN) across the waters of England, Wales, the Channel Islands, and Gibraltar. Each monitored site is equipped with out-station telemetry units, which facilitate both the remote control of fixed navigational aids and the observation of their performance and reliability. To ensure a thorough understanding of the existing system and our future requirements, Trinity House is hosting an Open Day. This event is intended for all interested parties to: - View the current CMCS in operation - Gain a clear understanding of both current capabilities and future needs - Discuss potential solutions and innovations with our technical team We welcome suppliers, developers, and other relevant stakeholders to attend and engage with us as we explore potential options. This open day will be held to provide a high level explanation of the existing systems and will take place in Harwich on Tuesday 2nd of September 2025. This will be strictly appointment only and an Non Disclosure Agreement (NDA) will be signed. Interested suppliers should email to request an appointment and a copy of the Trinity House CM12 Request for Information (if not already provided).
