Introduction

Autonomous sailing refers to vessels in which navigation functions are partly or fully performed by automated systems or remote operators. The level of human involvement varies by vessel, route and operational context. Fully autonomous operation remains limited to specific use cases and controlled conditions. Autonomous docking and mooring are covered in a separate factsheet

Value proposition

  • Workforce flexibility and safer task allocation:

    Selected monitoring and navigation tasks can move from the vessel to shore, reducing exposure to hazardous onboard work. Qualified operators remain essential for supervision and exceptional situations. Benefits: helps address crew shortages and creates shore-based roles. Condition: training, system reliability and clear responsibilities.

  • Operational reliability

    Automated navigation can combine voyage plans with real-time traffic, weather and waterway information. This may improve arrival predictability, energy use and schedule reliability. Benefits are use-case dependent; conventional vessels can achieve part of these gains through existing decision-support services.

  • Smarter port calls

    Connection with port-call and traffic-management systems can improve arrival information, berth planning and coordination. Full benefits also depend on compatible docking, mooring and terminal processes.

Port applicability

All ports are likely to encounter increasingly automated vessels, but the mix of conventional, assisted, remotely operated and autonomous vessels will differ. Early port-facing applications are most likely on repeatable routes and within defined operational areas. Vessel renewal is gradual, so mixed traffic will remain normal for decades. Ports should prepare for safe interaction between vessels with different automation levels rather than assume rapid fleet-wide autonomy.

Groups of innovations

  • Navigation assistance and partial automation

    Systems support route keeping, collision avoidance and manoeuvring while a qualified person remains responsible. Timing: available and scaling; Pros: incremental introduction; Cons: performance depends on sensors, context and human-system interaction.

  • Remote vessel operation

    Remote operators monitor or control vessels from a Remote Operations Centre using sensor data, video and secure communications. Timing: commercially applied in selected inland-waterway operations; Pros: workforce flexibility; Cons: connectivity, certification and fallback are critical.

  • Higher autonomy in defined domains

    The vessel performs navigation functions within specified routes, weather limits and traffic conditions. Timing: pilots and selected applications; Pros: repeatable operation; Cons: small craft, debris, locks, bridges, changing water levels and incomplete AIS data remain challenging.

  • VTS and port-system interaction

    Ports and vessels exchange identity, position, route intentions, operational status and alerts. Timing: short to medium term; Pros: improves coordination; Cons: interoperable standards and governance are still developing.

Port characteristics

Implementation depends on the automation level, vessels calling at the port and local waterway conditions. Modern VTS, reliable communications and digital port-call systems support early deployment, but autonomous vessels must also operate safely where port digitalisation is limited. Ports serving repeatable routes or newer fleets may face the transition earlier. Mixed traffic, locks, bridges, changing water levels, small craft, floating debris and incomplete AIS data require particular attention.

Barriers and enablers

Enablers

  • DirectionalityEnabler

    Crew shortages, pilots and regulatory progress support selected applications.

  • TechnologyEnabler

    Sensors and decision-support systemsare progressing, but performance remains operational-domain dependent.

Barriers

  • Stakeholder interactionBarrier

    Cooperation is essential; unclear responsibilities can quickly become a barrier.

  • EconomicBarrier

    High vessel-side costs and an uncertain short-term business case limit uptake.

  • RegulationBarrier

    The MASS Code provides a framework, but mandatory rules, local approvals and liability continue to develop.

  • KnowledgeBarrier

    Limited operational evidence and competence can slow approval and acceptance.

How to implement?

  1. Step 1

    Select suitable vessels, routes and port operations

  2. Step 2

    Review VTS, connectivity, cybersecurity, sensors and digital systems

  3. Step 3

    Define responsibilities, data exchange, approavals and fallback procedures

  4. Step 4

    Simulate and test normal operations, communication loss and emergencies

  5. Step 5

    Connect approved vessels with VTS, port-call systems and terminal planning

  6. Step 6

    Expand to more vessels and revies procedures as standards develop

* Technical Readiness Level

What should a port do in the next 3 years?

Ports should identify one realistic use case and assess local readiness. They should enable controlled pilots, agree responsibilities and fallback procedures, and train VTS, harbourmaster and emergency-response staff. Low-regret investments in connectivity, cybersecurity and system interfaces should precede major infrastructure commitments.

Investment overview

CAPEX: Potential investments include secure communications, VTS and port-system interfaces, cybersecurity, local sensors and test infrastructure. Remote Operations Centres and onboard autonomy are normally funded by vessel operators or technology providers. Major port investments should follow a use-case-specific readiness assessment. OPEX: Recurring costs include maintenance, connectivity, software, cybersecurity, monitoring, training and emergency exercises. Additional capacity may initially be needed for authorisation and supervision. Potential savings should be validated in pilots.

Stakeholder overview

Below is an overview of the required involved stakeholders. Port authorities, harbour masters and VTS organisations coordinate local access, traffic and emergency procedures within their mandates. Shipowners, operators and technology providers define vessel capabilities and operational limits. Flag states, classification societies, insurers and national authorities support certification, liability and approval. For inland navigation, waterway authorities, national regulators and river commissions such as the CCNR are also relevant. Terminal operators, pilots, emergency services, training institutes and workforce representatives should be involved where their operations are affected.
