无人船是一个有趣的提议，它可以实现慢速航行并节省燃料，同时避免船员必须留在船上进行很长的深海航行。为了保持效率和安全，必须实现船舶自主运行，而不需要 SCC 持续控制船舶。因此，船舶和岸上控制中心（SCC）之间的通信对于无人船至关重要，需要采取适当的安全预防措施，包括足够的冗余和备份解决方案。通信系统应能够提供至少 4 兆比特/秒的速率，以便从 SCC 进行完全远程控制，但减少操作后可维持在低至 125 千比特/秒。在自主模式下，所需的通信带宽将非常低。对于自主船舶，从船到岸的带宽要求更高，这与普通船舶的情况相反。通信的成本和可用性是一个问题。技术和功能指标的使用将使 SCC 能够在操作员和通信系统的最小负载下监控船舶的状态。信息传输的安全性和完整性至关重要，必须采取适当的手段来确保系统的容错和故障安全特性。
Unmanned ships is an interesting proposal to implement slow steaming and saving fuel while avoiding that the crew has to stay on board for very long deep-sea passages. To maintain efficiency and safety, autonomy has to be implemented to enable the ship to operate without requiring the SCC to continuously control the ship. Communication between ship and a shore control center (SCC) is therefore critical for the unmanned ship and proper safety and security precautions are required, including sufficient redundancy and backup solutions. Communication systems should be able to supply at least 4 Megabits/second for full remote control from SCC, but reduced operation can be maintained at down to 125 kilobits/second. In autonomous mode, the required communication bandwidth will be very low. For an autonomous ship the higher bandwidth requirements are from ship to shore which is the opposite of the situation for normal ships. Cost and availability of communication is an issue. The use of technical and functional indexes will enable the SCC to monitor the status of the ship at minimum load on operators and on the communication systems. The security and integrity of information transfers is crucial and appropriate means must be taken to ensure failure tolerance and fail to safe properties of the system.
