Silicon paints

What is your view on silicon paints for hull? Worth the investment?

Hi @Philip.Argyropoulos,

In the first stage, silicon paints might sound like an expensive choice.

Case studies of converting existing vessels from a biocidal antifouling to a premium, biocide-free advanced hull coating prove to reduce fuel consumption and CO2 emissions.

On average, an evaluation of 16 vessels achieved savings of just over 1,250 tons of fuel and 4,000 tons of CO2 per year.

If you are evaluating whether silicone paints are worth investing in existing vessels, I recommend you to check the Gold Standard Foundation.

Working with Gold Standard, you can implement a marine-based methodology for generating carbon credits within the shipping industry.

For the above example/case study, the efficiency improvement was translated to 126,785 credits.

Once the carbon credits are issued they can be:

  1. sold at market price and the revenue shared amonth the involved parties (paint provider/shipowner)
  2. can be passed on to important stakeholders to offset their emissions or
  3. can be used to voluntarily offset other sources of CO2 emissions.

Another advantage is that the generation of carbon credits demonstrates sustainability leadership and can enhance the reputation of ship owners/operators.

There are two sides to every coin :wink:


Hi @Stela.Spiraj ,

Thank you for your input. Is there any additional considerations and precautions during underwater when the hull is silicon coated?
