Unmanned Surface Vessels (USVs) are perhaps the most visible smart shipping applications to date in the Netherlands. Several developers of USVs and USV technology are commercially successful in the Netherlands, and various dredging and offshore instruction companies in the Netherlands are already starting to use USVs in their daily operation.
In the context of this roadmap, we define USVs as small vessels (<20 m for inland vessels, <24 m for seagoing vessels). Unmanned Surface Vessels are, as the name implies, not equipped for the carriage of people, so small autonomous ferries are not meant in this sense. Ferries have their own challenges and different market drivers, which are described in the inland ferry use case.
Although a lot of USV technology is developed and used in a military context, this roadmap focuses on civilian applications of USVs.

Functional requirements of communication systems
To enable remote monitoring and especially remote control of vessels, the functionality, reliability and cybersecurity of the vessel-shore communication systems need to be substantially improved. This begins with clear functional requirements to these systems, which are dependent upon the functional requirements set for the navigation, control and remote control systems.
Performance standards for communication and cybersecurity systems have been written by class societies, but current standards for position and ship information are inadequate for autonomous navigation or remote control, and requirements for reliability and redundancy of these communications need to be re-evaluated.
Development and testing of such standards is essential for the development of new regulatory instruments, both in IMO and for national legislation, and needs to be done in conjunction with the other system developments.
Furthermore, connectivity standards will significantly vary for inland and offshore operation, as inland operation faces specific challenges like connectivity under bridges or at country borders depending on the type of operation.
Ship position information systems
To facilitate safe autonomous or remote navigation, the digital position and navigational information of ships needs to be improved beyond current standards in reliability, accuracy and frequency of reporting. The dependence upon accurate ship position information is much greater, calling for a higher standard of reliability. Due to the specific issues in the operation of USVs, like the poor visibility of the vessels in seagoing conditions, non-availability of crew for VHF communication additional emphasis on standardized external data which can be used by other vessel traffic is important for navigational safety.
Standards for positioning systems and exchange of navigational information can only be developed internationally. Developments of these standards can be accelerated from the Netherlands by sound technical proposals but are ultimately dependent upon international co-operation in IMO or as a minimum between European flag and coastal authorities.
Autonomous shipping would benefit most if these digital information systems were made mandatory for all ships (like AIS), but the timeframe for implementation of such global standards will be too slow to allow implementation of the required autonomy before 2030, and therefore such standards cannot be relied upon for development of autonomous/remote operation systems in the timeframe before 2030.
Ship-ship and ship-shore communication protocols
As with reliable and accurate ship position information systems, digitalised ship-ship and ship-shore communications are required to efficiently integrate autonomously navigating ships into vessel traffic systems. Communication protocols need to be standardised internationally, requiring significant international co-operation.
Cybersecurity needs to be addressed from the perspective of system communications. Currently developed standards are adequate for partial system connectivity, but integration into a wider system of ship-shore communication is untested.
Connectivity for smart shipping on the North Sea
Depending on the requirements set forth in the functional and technical requirements for ship-ship and ship-shore connectivity, the connectivity for both sea and coastal areas will need to be improved. This is especially important for congested areas such as harbour approaches and crossings in the shipping lanes, where remote access to camera and other telemetry data is usually required for shore operators. Without the development of the technical requirements, it is however not yet possible to determine exactly what connectivity is required, hence implementation cannot start before such requirements are clear.
Although it is technically possible through satellite communication to provide the required connectivity, the main challenge is to do so in a cost-effe ctive manner in which other solutions can become an alternative.
Alternative solutions (4G/5G) may be extended to key areas, but it is not clear who should take the initiative or how costs for such infrastructure is to be distributed.
Furthermore, even when these standards have been established, the implementation of these connectivity solutions will depend on the willingness of coastal states and/or telecom providers to invest in such infrastructure. However, the cost recovery model is not clear, which is especially important where commercial operators are relied upon.
