Technology group Wärtsilä recently outlined four trends and technologies that our experts see affecting the maritime industry in 2026: 

Trend 1 – Lifecycle optimisation

With emissions regulations evolving rapidly and technologies for ships advancing at lightning speed, the days of inflexible vessel designs and short-term thinking are over. What makes financial and operational sense today might not make sense in a year or even six months.

Age is no longer the sole determining factor for vessel owners when making decisions on fleet renewal. Older ships that have been well maintained and incrementally upgraded can outperform younger vessels that have not benefitted from best-practice maintenance approaches and timely investments in upgrades.

A long-term, holistic view

Efficiency improvements can demand significant capital expenditure and will probably need to be staggered over several years. This is why today’s vessel owners and operators are increasingly taking a longer-term, more holistic view of the vessel lifecycle. This helps them to make the right investments at the right time – and preserve the long-term value of their assets.

The trend towards a lifecycle optimisation approach is driven by the need to decarbonise and the need to reduce costs. Lifecycle optimisation is a holistic approach that takes account of environmental impact, operational efficiency and economic viability from the vessel design phase to the end of its operational lifespan. 

A tailored plan for each vessel and business case

In the maritime segment lifecycle optimisation means different things to different businesses. Some, like ferry and offshore operators, are primarily driven by the need to maximise vessel uptime and time between overhauls. Others, for example charterers in the tanker or bulker segment, are driven by the need to minimise fuel costs

For any lifecycle optimisation approach to be successful, it is critical that it is based on a deep understanding of the total cost of ownership. Developing this kind of understanding demands openness and transparency between owners, operators and OEMs. To this end, there is a shift in the industry towards building relationships that are founded on these principles.

When owners, operators and OEMs share their experiences and hard data, they are in a much better position to build a lifecycle optimisation approach that will deliver maximum benefits over the vessel lifecycle. It is an unavoidable reality that the costs associated with carbon taxes, emissions credits and other regulatory instruments are only going to increase. With that in mind, it makes sense to take a long-term view founded on incremental improvements rather than short-term fixes.

Lifecycle services bring clarity

In an increasingly volatile and uncertain environment, vessel owners and operators are placing high value on elements that bring them some degree of certainty – a solid platform to plan for the future and remain competitive in the long term. Lifecycle services and expert advice can make a positive contribution in this regard.

Dynamic maintenance planning can help owners lower lifecycle costs by making smarter decisions on when to carry out engine maintenance and overhauls. On the operational side, digital fleet optimisation solutions and route planning can bring a more holistic overview of vessel performance and fuel consumption, helping to identify areas for improvement.

Predictive maintenance services enhanced by artificial intelligence can improve reliability over the vessel lifecycle. With direct access to a wealth of vessel data, these smart services can prevent minor symptoms from becoming major problems by providing crews with timely corrective maintenance recommendations.

Detailed vessel simulation models can demonstrate how upgrades and other adjustments will impact total cost of ownership over the lifecycle of a vessel. This information supports smarter decision-making, bringing clarity over what to invest in, when to invest and the expected returns on these investments.

Trend 2 – Flexible decarbonisation strategies

Decarbonisation means different things to different businesses. It depends on the vessel type, its operational profile, the availability of alternative fuels and the ability to offload captured carbon, for example. Whatever way businesses respond to the need to decarbonise, all the responses have one thing in common – they have to make commercial sense.

Decarbonisation is an opportunity to be more efficient. To make best use of this opportunity companies need a properly thought out decarbonisation strategy with flexibility at the core. This strategy will be informed by operational factors, but also by business drivers and priorities, available capital and the financial risks associated with waiting to see what happens. All these variables mean that there is no one-size-fits-all decarbonisation strategy, no silver bullet, and that flexible decarbonisations strategies will remain important for the foreseeable future.

There are three main stages to developing an actionable decarbonisation strategy. Firstly, the planning stage, where equipment – from engines to energy saving devices to carbon capture and storage – is selected to achieve the goals of the strategy. Secondly the installation and systems integration phase. And thirdly the monitoring phase, where results are continuously monitored and adjusted to ensure the expected outcomes are being achieved.

Flexibility is key

Not so long ago, when investing in a newbuild vessel we could be pretty sure that, with proper maintenance, the technology on board would be good for 20 years. Today the only thing we can be sure about is that whatever technology we invest in, it will be out of date in 20 years.

This leads to complex choices. How much do we spend on the latest technologies now and how much do we save to upgrade to more relevant technologies in five or ten years? How much space should we reserve for carbon capture and storage solutions, rotor sails or alternative fuel tanks and handling systems in the future?

You don’t want to put the CAPEX there too early, but making effective changes becomes too expensive if you don’t prepare at the start. In the worst case scenario, without a proper plan, a newbuild vessel could become a stranded asset many years before its time.

The only answer to this challenge is built-in flexibility. Start with a fuel roadmap that makes sense for the vessel’s planned operational profile. Fuel-flexible engines are key here so that they can stay relevant throughout your journey from, say, diesel/LNG to bioLNG to methanol.

Integrate a hybrid solution where possible and use data to demonstrate what energy saving technologies can best complement your vessel’s design. Have a plan for what additional technology will be installed later and make sure there is enough space on board to accommodate it.
