White paper: Could AI and data help reduce downtime? The best answers from real vessels

Downtime is expensive – and schedule-based maintenance can still miss what’s developing between inspections. Learn what changes when real-time data, AI diagnostics, and human expertise work together in ship maintenance – and how operators have reduced unscheduled maintenance by 25% on average.

Three proven ways to cut downtime – backed by six real vessel examples

Unscheduled downtime doesn’t just disrupt operations – it can quickly turn into lost revenue, missed commitments, penalties, and urgent repair costs. Maintenance based only on fixed schedules can also lead to over-maintenance or hidden issues developing between inspections.

If you want fewer surprises and more control over cost and risk, you need evidence of what works in real vessel operations – and that’s exactly what this paper delivers. In real operations, 90% of issues are resolved remotely and 80% within 24 hours, helping crews restore normal operation faster and avoid downtime.

Could AI and data help reduce downtime cover whitepaper

Can AI really reduce unscheduled maintenance – and what results are realistic?

Downtime often starts as a small deviation that’s easy to miss until it becomes a real operational problem. This paper explains how AI and rule-based diagnostics can detect weak signals early – and how experts filter and validate what matters so crews aren’t flooded with noise. If you’re accountable for uptime, you’ll want to see what this looks like in real vessels, not theory. The hard part is balancing reliability with cost: you want engines in good condition, but you also want to avoid unnecessary maintenance and disruption. The paper shows how data-driven planning can safely extend maintenance intervals based on actual engine condition.

You will get:

Practical insight: Learn how predictive maintenance detects early deviations and helps crews act before issues turn into costly downtime.
Proven results: See how real vessels use AI-enabled maintenance in day-to-day operations – and what that means in practice when it comes to avoided failures, faster resolution, and reduced downtime.
Smarter planning: Discover how to extend maintenance intervals safely using data-driven planning based on actual engine condition.
Greater confidence: Learn how engine data, inspections and expert validation can reduce unnecessary maintenance while maintaining safety and compliance.

If you’re considering how to reduce downtime without increasing operational risk, you need more than promises – you need proof, decision logic, and practical examples. This paper helps you see what’s proven to work , what the trade-offs are, and where AI and data make the biggest difference.

Predictive maintenance that pays off: what offshore and LNG cases reveal

Stay ahead of downtime

AI and rule-based diagnostics can spot early deviations that humans can’t reliably see in time. Real-life examples in this paper show how those signals are filtered and validated, so crews can act early – before a small anomaly becomes downtime.

Make maintenance decisions with confidence

Fixed schedules don’t reflect real wear. The paper proves how data-driven maintenance planning helps you extend intervals safely and with minimal disruption.

Resolve issues faster with expert support

When an issue happens, speed matters. The paper includes real examples of remote troubleshooting and notes that many issues are solved over a remote connection – 90% remotely and 80% within 24 hours in real operations.

Frequently asked questions

Who is this white paper for?

Ship owners and operators who want to improve the reliability of their vessel operations.will find this Wärtsilä white paper interesting.

How does AI reduce vessel downtime in practice?

AI and data help reduce vessel downtime in several practical ways. Predictive maintenance can detect small deviations early and flag them for expert validation, helping crews act before issues turn into failures. Data-driven maintenance planning enables safer decisions on when maintenance is truly needed, reducing unnecessary work and avoiding disruptions. Remote expert support helps resolve issues quickly when they occur, often without the need for an onboard visit.

This white paper shares six real vessel examples that show how these approaches work together in practice to reduce downtime and costs.

What results are realistic from predictive maintenance on ships?

Results depend on vessel type and operating profile, but the paper includes real cases with quantified outcomes – including examples where unplanned costs were avoided by resolving validated issues before escalation. It also states that, on average, unscheduled maintenance was reduced by 25% on an average across monitored operations.

Can maintenance intervals be extended safely – and still meet compliance expectations?

The paper describes data-driven maintenance planning that uses engine condition data and inspections to show when maintenance is truly needed, enabling intervals to be extended safely where appropriate. It also explains how an OEM statement can be used to demonstrate to classification societies that the vessel remains compliant and safe to operate.

What about cyber security when using connected, AI-enabled maintenance services?

The paper highlights cyber security as a key factor and notes that connected ships must protect safety, continuity, compliance, and reputation – not just IT systems. It lists examples of relevant frameworks/requirements referenced in the paper (e.g., IACS UR E27, ISO/IEC 27001:2022, GDPR, CRA) and mentions ongoing alignment with newer EU legislation such as the Data Act and AI Act.
