Comprehensive Ship Maintenance Cuts Emissions, Boosts Efficiency

In the world of maritime transport, the quest for greener operations is never-ending. A recent study published in the Journal of Marine Science and Engineering, titled “Reducing Ship Emissions Through Specialized Maintenance: A Case Study Based on Real Data,” sheds light on a often-overlooked aspect of ship management: maintenance. The lead author, Sonia Zaragoza from the Ferrol Engineering Polytechnic University College at the University of A Coruña in Spain, has been digging into how maintenance can be a game-changer in reducing emissions and improving energy efficiency.

Zaragoza and her team took a close look at two liquefied natural gas (LNG) carriers, analyzing their performance before and after maintenance operations. The results are pretty striking. Comprehensive maintenance, like a complete hull and propeller cleaning, can slash fuel consumption by over 30% and cut CO2 emissions by more than 15%. Plus, it can boost propulsive efficiency by a whopping 18% to 34%. That’s not just good for the environment; it’s great for the bottom line.

But here’s the kicker: not all maintenance is created equal. Minor interventions, like underwater propeller cleaning, only offer limited benefits. They might save some fuel at certain speeds, but they don’t make a significant dent in emissions or shaft power. So, it’s not just about maintaining your ship; it’s about doing it right.

Zaragoza points out that a single comprehensive maintenance operation can even change a ship’s Carbon Intensity Indicator (CII) rating from category E to D. That’s a big deal in today’s maritime landscape, where emissions regulations are getting stricter by the day. “Maintenance is not just about keeping the ship running; it’s a strategic tool for decarbonization and revaluation of maritime transport,” Zaragoza emphasizes.

So, what does this mean for the maritime industry? Well, it’s a wake-up call. Shipowners and operators need to start seeing maintenance as more than just a necessary evil. It’s an opportunity to cut costs, reduce emissions, and stay ahead of the regulatory curve. And with the right approach, it can be a powerful tool in the fight against climate change.

In the words of Zaragoza, “The results show that comprehensive actions such as complete hull and propeller cleaning can reduce fuel consumption by more than 30% and CO2 emissions by more than 15%.” That’s a pretty compelling argument for investing in comprehensive maintenance, isn’t it?

As the maritime industry continues to grapple with the challenges of decarbonization, studies like this one are more important than ever. They provide a roadmap for shipowners and operators, showing them how to navigate the complex waters of emissions regulations and energy efficiency. And with the right approach to maintenance, they can make a real difference in the fight against climate change.

So, let’s raise a glass to Sonia Zaragoza and her team. They’ve given us a powerful tool in the fight against climate change. Now, it’s up to the maritime industry to use it wisely.
