How ventilation can facilitate the maritime green shift

While climate has become a top priority in most industry sectors, the maritime green shift has been a slow-starter. However, with rising fuel costs there is a growing need to reduce energy waste. Installing high quality air-tight ventilation systems on ferries and cruise ships is one central measure to lower the use of energy in the maritime sector while at the same time reducing emissions and saving money.

High demand for energy efficiency improvements

Maritime is inevitably the most energy efficient way to transport goods and people. To reach the climate targets set by the EU, transport volumes will increasingly have to be transferred to sea-based alternatives. At the same time, as the cost of fossil fuel keep rising there is also an increasing need for the maritime sector to adopt new techniques, alternative fuels and work to increase energy efficiency.

The need for innovation is driven by economic logic, but increasingly by political pressure too. The Norwegian parliament for example recently passed a resolution to halt emissions from cruise ships and ferries in the Norwegian fjords as soon as technically possible and no later than 2026. Similar decisions will probably follow in other parts of the world in the years to come.

Better ventilation is key to lowering fuel consumption

That is why innovation needs to become a priority in the maritime sector. Finding viable alternatives to fossil fuel is important, but measures aimed at improving energy efficiency will also become critical. Among the measures that are being discussed are recycling engine heat, installing solar panels and optimising the ventilation ducts. You might be surprised to hear this, but on some cruise ships the ventilation system uses as much as a third of the ship’s total fuel consumption.

Lindab has delivered ventilation solutions to the maritime sector including navy, cargo, offshore, ferries and cruise ships for more than three decades. By understanding the demanding conditions that ships are exposed to in the form of wind and water and developing solutions of the highest quality, we have managed to become one of the leading companies on the market. For example, of the 16 large cruise ships set to be completed this year, Lindab is the main supplier of ventilation solutions on six.

A new standard for marine ventilation solutions

Looking ahead it is clear that reducing fuel consumption will remain one of the largest challenges for the maritime sector. The fact that Lindab is one of few manufacturers on the market that offer duct systems certified in the highest Eurovent category gives us an edge in competition with others.

With the new generation of our ISOL solution, Lindab also sets a new standard for effective, high-performance marine air ducting systems. Thanks to a new stop bead there is less need for adjustment. The edges of the ducts are now also folded over to minimise sharp surfaces and reduce the risk of installer injury. The result? A fully-optimised solution that is faster and easier to install and that will increase energy efficiency.

That is great news for the climate, but also something that makes economic sense for the ship builders. We call it Good thinking!
