Beyond the Inspection

When people think about shipyards, they often picture welders, cranes, steel, and months of hard work returning a vessel to service. What they don't always see is the planning that makes every successful maintenance period possible.

Long before a wrench is turned, vessel owners, engineers, fabricators, and shipyard teams are making hundreds of decisions about what needs to be repaired, what can wait, and how to complete the work safely and efficiently. Those decisions are only as good as the information available. That's where we believe the future of maritime maintenance is changing.

Recently, Tiamat Maritime partnered with Cooper Curtis and the incredible team at Highmark Marine Group in Kodiak, Alaska, to demonstrate what that future could look like. And we did this, not by replacing the expertise already found in the shipyard, but by giving experienced professionals better information before work begins.

Together, we launched a pilot focused on building a digital foundation for smarter vessel maintenance.

Building the Digital Baseline

The project centered on the M/V Stellar Wind, an 85-foot icebreaker tugboat undergoing a scheduled maintenance period.

Rather than conducting another point-in-time inspection, our objective was to create something that would continue delivering value long after the vessel returned to service.

Using high-resolution drone imagery and LiDAR, our team created the first-stage digital twin of the vessel's interior and exterior.

The result was the beginning of a persistent digital record and baseline that can be updated during every future maintenance period rather than relying on disconnected photographs, handwritten notes, and memory.

Human Judgment & Machine Precision

One of the most valuable discoveries came during the review of the spatial model. The digital scan identified four hull indents that met the U.S. Coast Guard patch criteria but had not been identified during traditional visual inspection.

Those findings were documented as part of the vessel's new digital baseline, providing the owner with a more complete understanding of the hull's condition and allowing those areas to be tracked and evaluated during future maintenance periods. Rather than relying on memory or disconnected inspection photos, the vessel now has a consistent digital record that can inform maintenance planning for years to come.

This is a powerful example of how the best outcomes are achieved when human judgment and machine precision work together. Machines excel at capturing exhaustive, repeatable, and highly accurate information. Experienced operators contribute something technology can’t do alone with context, judgment, and decades of hard-earned maritime expertise.

At Tiamat Maritime, we believe technology is most valuable when it helps experienced professionals make better decisions. By combining machine precision with human judgment, we provide vessel owners and maintenance teams with the

information they need to plan proactively, reduce uncertainty, and better manage assets throughout their lifecycle.

The Power Is in the Planning

Following the project, the vessel owner estimated that having a complete spatial model before the maintenance period could have reduced repair costs by 10–15% on a maintenance project valued at approximately $500,000 through better planning, work sequencing, and preparation.

The most expensive part of any maintenance period is often discovery. When unexpected issues are found after a vessel has already been hauled out, schedules shift, fabrication changes, materials must be reordered, and labor waits.

Better information before maintenance begins changes that equation.

With a comprehensive digital model, owners and shipyards can scope repairs more accurately, coordinate resources earlier, stage fabrication, and make informed decisions before valuable time out of the water is lost.

More importantly, the digital model becomes a repeatable inspection framework. Rather than beginning each maintenance period from scratch, technicians and inspectors can return to the exact same locations every time. They have access to dimensions and access requirements for confined spaces, equipment locations, valve models, serial numbers, safety equipment, and other critical asset information. Then all of this information is organized within a consistent digital environment.

Every inspection builds on the last instead of starting over, and that's where time, money, and operational efficiency are truly gained.

Building the Future of Vessel Maintenance

The future of maritime maintenance will be built on the combination of experienced professionals, reliable data, and technologies that provide greater visibility before work begins.

Imagine entering a maintenance period with a searchable digital model of the vessel instead of relying on scattered photographs and handwritten notes.

Imagine comparing today's inspection with every previous inspection to understand exactly how an asset has changed over time.

Imagine vessel owners, engineers, surveyors, and fabricators working from the same digital understanding of the same asset both above and below the waterline.

Instead of collecting another folder of still images that gradually lose context, each inspection builds upon the last, creating a consistent digital record that becomes more valuable throughout the vessel's lifecycle. That's the inspections of the future.

Collaboration in Action

The most meaningful advances in the maritime industry are built through collaboration between organizations that bring different expertise to the table.

We're grateful to Cooper Curtis and his entire team for embracing that mindset. Their willingness to collaborate and challenge conventional approaches made this pilot possible.

Highmark brought decades of shipyard knowledge, fabrication expertise, and an understanding of what truly matters during maintenance availability. Tiamat brought aerial capture, spatial mapping, digital twin technology, and a vision for creating persistent maritime intelligence.

Together, we're demonstrating that the future of vessel maintenance isn't built by software alone or by shipyards alone.

Looking Ahead

The Stellar Wind now has something it has never had before: a digital baseline.

Every future inspection can build upon that foundation, allowing owners to compare conditions over time, improve maintenance planning, and make more informed lifecycle decisions.

For us, success looks like helping owners, engineers, and shipyards make better decisions because they have better information.

This is only the beginning.
