More than 5,000 maritime organisations screened down to 150. Thetius' latest research puts shipowners at the centre of two transformations that have often been treated separately: digitalisation and decarbonisation.

The connection is becoming increasingly operational. Data has to move from the bridge to the office and into the decisions that determine how vessels are routed, operated and ultimately how much fuel and carbon they consume.

The next phase will depend less on the availability of technology and more on an owner's ability to turn digital capability into measurable vessel performance.

The 2026 Thetius Top 150 is not a ranking, and the report says so on its first page of substance. Organisations appear alphabetically within four categories, selected on the strength of what they actually did between June 2025 and June 2026. Contract wins and MoUs count for little. A signal only qualifies if it shows a company doing something new or doing something better. That discipline is what makes the funnel from 5,000 organisations to 150 worth taking seriously, and it is why the list reads less like a marketing exercise and more like an audit of where maritime technology has genuinely moved.

The three forewords tell a consistent story from three very different vantage points. Lloyd's Register's Mark Warner opens by dismissing the framing that has dominated the past decade: the maritime digital problem, he writes, is not a technology problem. The barriers are organisational. Trusted data, governance, a ready workforce and a clear strategy decide outcomes, and LR's own Digital Maturity Index, now benchmarking more than 70 companies, exists precisely because so many owners cannot say where they stand. Kaleris quotes a customer at one of its workshops: "We don't lack data. We lack agreement on what's actually happening." And the SME foreword paints the sharpest picture of all, a chief officer awake at 03:00 not because the sea demands it but because a spreadsheet does, defending good work with the wrong tools when SIRE 2.0 and TMSA come calling.

That is the state of the industry in one image. Ships now generate more data than ever, connectivity is no longer scarce, and AI budgets are growing. Yet the value is trapped between systems that were bought separately and never taught to speak to each other. Digitalisation and decarbonisation suffer from the same fault, because they depend on the same feeds about speed, routing, fuel and port time. A performance platform that cannot inform an emissions calculation is half a tool.

What makes this year's list encouraging is that shipowners are no longer waiting for suppliers to solve it. Lomar, with more than 80 vessels, has used lomarlabs to put AI-assisted pilotage on a tanker, predictive behavioural analytics into its operations and a methane removal system aboard a supramax within a single year. GTT Marine's 17,000 installed units show the supply side converging on the same integrated approach.

The report's closing thought belongs to LR: the next phase will be defined by confidence in data and in the decisions built on it. Owners who earn that confidence will meet tightening regulation and demanding charterers on their own terms. The rest will keep adding technology and wondering why nothing changes.

SMM special discount: Digital Ship Summit tickets for just £295

On 15 October, 150 senior maritime IT leaders will come together in Athens for the Digital Ship Summit.

Built by and for shipowners and ship managers, the one-day, single-track programme brings CIOs, CTOs and Heads of IT into the same room to discuss the decisions shaping the next decade of maritime IT — from data and infrastructure to cyber resilience, connectivity, AI and automation.

If you're attending SMM, there's a limited-time opportunity to join us for £295.

Early-bird tickets are currently £295 until 7 September, before rising to the standard £695 rate. That's £400 off the standard ticket price.
