Will AI Replace Marine Traffic Controllers? Radar Sees More, But Humans Still Call the Shots

68% of vessel traffic monitoring on radar and AIS displays can now be handled by AI. If you''re a marine traffic controller watching ships crawl across your screen right now, you''ve probably already noticed — the system highlights the conflicts before you do, predicts the crossing situations you used to calculate mentally, and tracks more targets simultaneously than any human could.

But try telling an AI to talk a panicking captain through a near-collision in a fog bank. Try asking it to coordinate a search-and-rescue across three jurisdictions when satellite comms are flickering and survivors have eight minutes before hypothermia. That''s where the numbers tell a very different story.

The Automation Split

Marine traffic controllers face 56% overall AI exposure with a 35% automation risk as of 2025. [Fact] That places this role in the high-exposure category — significantly above most maritime operations jobs. But the risk is concentrated unevenly across tasks, and understanding that uneven distribution is the difference between panicking about your career and planning it.

Monitoring vessel positions and traffic patterns on radar and AIS displays leads at 68% automation. [Fact] This is the bread and butter of vessel traffic services, and AI is genuinely good at it. Pattern recognition algorithms can track hundreds of vessels simultaneously, predict course conflicts minutes before they develop, calculate Closest Point of Approach values continuously across the entire traffic picture, and flag unusual movements that might indicate a vessel in distress, a non-compliant operator, or a target straying from its assigned traffic separation scheme. Systems like Wartsila''s Smart Marine ecosystem and Saab''s V3000 VTS suite have moved well beyond simple radar plotting into genuine decision support.

Communicating navigation advisories and clearances to vessel operators sits at 35%. [Fact] Routine clearances and standard advisories are increasingly automated — think of automated weather broadcasts, pre-programmed VHF messages for pilot boarding instructions, and standardized port entry communications. But anything non-standard requires human judgment about how to phrase an advisory, when to be direct versus diplomatic, and how to read the tone of a vessel operator who might be confused, non-native English speaking, exhausted after a thirty-hour bridge watch, or experiencing equipment problems they have not yet admitted to.

Coordinating emergency response for maritime incidents and distress calls drops to just 15% automation. [Fact] When a vessel sends a Mayday, the response requires instant coordination across coast guard units, nearby commercial vessels who can divert under SOLAS obligations, helicopter SAR services, port authorities, salvage tugs, and increasingly environmental response teams from multiple jurisdictions. It demands judgment calls about search patterns, survivor probability, resource allocation, and political sensitivities that change by the minute. No AI system currently deployed in maritime operations can manage that complexity, and no regulator is anywhere close to certifying one.

A Growing Field Despite AI

Here is something that might surprise you: BLS projects +2% growth for this occupation through 2034. [Fact] With about 5,100 workers currently earning a median salary of $58,340, [Fact] the field is stable and modestly expanding. Global shipping volumes continue to increase, ports are handling larger vessels with tighter margins, and waterway traffic in congested areas like the Strait of Malacca, the English Channel, the approaches to Singapore, the Houston Ship Channel, and Rotterdam keeps growing. Ultra-Large Container Vessels carrying 24,000 TEU need pilots with vessel traffic support that can manage their margins of less than a meter on each side in confined waters.

More traffic means more need for oversight, even if AI handles much of the routine monitoring. The controller''s role is shifting from watching screens to managing the AI systems that watch screens — and stepping in when those systems encounter situations outside their training data. That''s an upgrade in cognitive demand, not a downgrade. The pay scale tells the story: experienced VTS operators in major port complexes routinely earn well above the median, especially in jurisdictions where regulatory frameworks recognize the role as safety-critical infrastructure.

The Air Traffic Control Parallel

Marine traffic control is following a trajectory similar to air traffic control, but about a decade behind. Aviation introduced automated conflict detection and resolution advisory systems years ago — TCAS, ASDE-X, and the various conflict probing tools used in Terminal Radar Approach Control facilities. The result wasn''t fewer controllers. It was controllers handling more traffic with higher safety margins, and a profession that retained its essential human core despite massive technology adoption.

The same pattern is emerging in maritime traffic management. The IMO''s e-Navigation Strategy, the European Union''s Common Information Sharing Environment, and individual port digitalization initiatives are bringing AI-augmented tools into VTS centers worldwide. None of these initiatives propose removing the human controller from the loop. They propose making the human controller more effective at handling complex traffic, fatigue management, and exception cases.

By 2028, overall exposure is projected to reach 70% with automation risk at 48%. [Estimate] The theoretical ceiling is 86%. [Estimate] These are high numbers, but the gap between theoretical (76% in 2025) and observed exposure (35%) shows that actual deployment in vessel traffic services lags far behind what''s technically possible. [Fact] Maritime regulatory bodies move slowly, and for good reason — the consequences of a system failure in a busy waterway are measured in environmental disasters, port closures that ripple through global supply chains, and human lives. The Ever Given grounding in the Suez Canal in 2021 cost the global economy an estimated $9.6 billion per day. Nobody is rushing to hand that kind of risk to an AI system without exhaustive validation.

What the Day-to-Day Looks Like in 2028

Picture a vessel traffic services operator in 2028 working a shift in a major port complex. The radar display has integrated AIS, satellite positioning, and predicted track data for every vessel in the area. AI agents continuously calculate conflict probabilities and propose advisories. A bulk carrier and a passenger ferry are on converging tracks — the system flags the conflict eight minutes out and suggests a one-point course adjustment for the bulk carrier.

The operator reviews the suggestion in two seconds. They notice something the algorithm missed: the passenger ferry is the regular morning service, and the operator knows from experience that this specific ferry captain prefers to maintain his published schedule even at the cost of slightly tighter clearances. The operator overrides the system''s suggestion, instead calling the bulk carrier directly to ask for a small speed reduction. The bulk carrier complies. The ferry passes clean. The published schedule is maintained. No incident occurs.

That two-second decision — combining algorithmic input, local knowledge, and human judgment about another human''s habits — is precisely what the 15% floor on emergency coordination automation captures. It is also what makes this profession AI-resilient.

Now scale that scenario across an eight-hour shift handling 200-plus vessel movements in a Tier-1 port like Rotterdam or Singapore. The operator is not doing less work because of AI assistance. They are doing different work — higher cognitive load, more exception handling, more decisions per hour, but also more decisions that actually require human judgment rather than rote pattern matching.

The Regulatory Reality Few Acknowledge

Maritime regulation is fundamentally different from technology development, and this gap explains why observed automation in VTS lags so far behind theoretical capability. The IMO operates by consensus among 175 member states. The IALA publishes guidelines that national authorities choose whether to adopt. Even when a port authority wants to deploy more aggressive AI automation, it must navigate flag state requirements, classification society approvals, insurance industry expectations, and the powerful conservative culture of mariners themselves.

That conservatism is rational. A maritime incident involving an automated system that fails will not just hurt the individuals involved. It will set back the entire regulatory framework for AI in maritime operations by years. Every stakeholder — from the IMO secretariat to the deck officer on a 400-meter container ship — understands this. The result is a deployment pattern that emphasizes augmentation over autonomy, advisory systems over decision-making systems, and human-in-the-loop architectures over end-to-end automation.

For the marine traffic controller, this regulatory inertia is career insurance. The technology to automate more of your job exists today. The institutional willingness to deploy it without you supervising it does not exist, and will not exist for at least another decade — likely two.

How to Position Yourself Now

The career advice splits into three tracks depending on where you are in your career. New entrants should pursue VTS operator certification, then layer on emergency response training and ideally a second language relevant to your operating area — Mandarin for Pacific ports, Arabic for the Gulf, Spanish for Latin American operations. Mid-career controllers should focus on supervisor certifications, incident command training, and developing expertise in the specific AI tools your VTS center is deploying so you can become the person who validates, calibrates, and trains others on those systems.

Senior controllers approaching the back half of their careers have the most distinctive opportunity: become the institutional memory that bridges the pre-AI and post-AI eras of vessel traffic management. The decisions about how to deploy AI tools, what override authority operators should retain, and how to structure training programs for the next generation are being made now. Senior controllers who can speak authoritatively about both the operational realities of vessel traffic services and the capabilities and limitations of modern AI systems are the people whose input shapes those decisions.

What This Means for Your Career

If you''re in this field or considering it, the trajectory is clear: the monitoring portion of your job will become increasingly AI-assisted, freeing you to focus on the high-judgment tasks that define the profession''s real value. Communication skills, emergency management experience, multi-language fluency, and the ability to coordinate multi-agency responses are the capabilities that will differentiate controllers as AI takes over routine traffic surveillance.

Invest in emergency response certifications. Build experience with the latest VTS software platforms. Pursue IALA''s Vessel Traffic Service operator and supervisor certifications. Develop expertise in incident command systems that integrate with land-based emergency management agencies. And recognize that the 15% automation rate on emergency coordination isn''t a ceiling on your career — it''s a floor under your job security.

The ships keep coming. The waterways keep getting more crowded. The need for a human watching the watchers is not going away.
