SMART-TUG · For tug owners and port operatorsAI · Real-time · ESG-ready

Right tug.
Right vessel.
Right time.

Smart-Tug turns tug scheduling from reactive guesswork into proactive orchestration.

Tugs are up to 50% of a port's marine fuel consumption. Berthing delays cost $25,000+ a day. And IMO 2030 is closing in. Smart-Tug rebuilds the 6-hour schedule whenever inputs change — vessel ETAs, pilot availability, weather, tug breakdowns — and keeps the port moving.

Why this is universal

Tugs move every ship in the port.
Manual scheduling now costs more than it ever did.

50%

Of a port's marine fuel

Tugs account for up to half of a port's marine fuel consumption — per a Port of Rotterdam study. Scheduling efficiency translates directly into emissions and cost.

$25K+

Daily berthing delay cost

Industry average — larger and busier ports carry significantly greater exposure when tug scheduling falls behind vessel arrivals.

IMO 2030

Carbon intensity deadline

Global emissions targets are tightening. Tug operations are now squarely in scope for ESG reporting and regulatory compliance.

What this means for your port

Fuel burn down

Smarter pairings and fewer repositioning runs — the optimization model puts fuel front and centre, then routes accordingly.

Berth delays down

Vessels meet their tugs on time; berth-window slip stops compounding into next-shift problems.

Tug utilization up

Idle time shrinks. Tug capacity aligns with the job mix instead of standing by on guesswork.

ESG line, sorted

IMO 2030 baked into the planner. Emissions tracked per job and per tug. Carbon-tax forecasts modelled before they hit.

What's broken today

Tug ops still run on spreadsheets and gut feel.

Four problems compound at every port without intelligent scheduling — each one quietly draining margin while emissions and delay costs climb.

Scheduling without predictive intelligence

Manual rosters built on experience and reactive planning. Pilot availability, vessel class, draft and engine condition all juggled by hand — and assumptions drift from real-time conditions.

High fuel costs from excessive repositioning

Tugs ping-pong between berths because no system optimizes where they should idle, refuel and stage for the next job. Fuel burn compounds across every wasted manoeuvre.

Lack of real-time adaptability

Vessels arrive early. Vessels arrive late. Tugs break down. Pilots get reassigned. Static schedules can't react in minutes — rebuilds happen on whiteboards, hours after the disruption.

Underutilized assets, operational blind spots

Idle tug time is frequent, yet utilization stays stubbornly suboptimal. Compliance with port safety rules — tugs-required by vessel class, draft and engine condition — gets inconsistent.

How Smart-Tug works

Four pillars. One scheduling engine.

AI scheduling

Predictive, not reactive.

AI-powered scheduling engine assigns tugs by job type, berth timing, vessel class and real-time availability. The plan is generated, not improvised.

Optimal tugs · optimal jobs

The right tug, every time.

Right tug at the right vessel at the right time. Cost and delay minimized across every assignment in the 6-hour planning window.

Continuous optimization

Live re-runs, not next-day fixes.

Live optimization, maximized utilization, smarter repositioning. When inputs change — vessel ETAs, breakdowns, weather — the schedule rebuilds on demand.

Operator-friendly

Built for the dispatcher.

Interactive UI for on-demand reruns and job adjustments. Operator-controlled delay buffers, partial job execution, smart rerun logic for updated inputs.

The 6-hour rolling window

Five tugs. Six hours.
Every job assigned, every vessel met.

The scheduling window updates in real time as vessel ETAs shift, pilots get reassigned and tugs come on or off station. Operators rerun the plan on demand and the schedule rebuilds in seconds.

Plan refresh time

Seconds

Operator hits rerun · revised schedule returned · before the dispatcher hangs up the call.

Platform features

Built for the dispatcher's desk.

6-hour rolling schedule window

Planning horizon updates live as vessel arrivals, departures and shifts move.

Operator-controlled delay buffers

Configurable thresholds for how much slip the schedule absorbs before re-optimizing.

Partial job execution support

Tugs released mid-job re-enter the dispatch pool without disrupting the plan.

Smart rerun logic

When inputs change, the engine re-optimizes only what needs to move.

High-value job prioritization

Larger vessels, tight windows and premium contracts surface first in the queue.

Built-in port safety rules

Tugs-required by vessel class, draft and engine condition enforced automatically.
