Underwater hull cleaning & propeller polishing

What are the benefits of Underwater Hull Cleaning?

Well, very simple, it saves you a lot of money. But not only that! You deal with the environment in a more sustainable way. We list the benefits for you:

Benefit 1 - Save significantly on your fuel costs

Fuel costs make up about 50% of a ship's total operating costs. Calculate what a saving of 50% means to your company.

Ships often lie still, allowing bio fouling to attach itself to the hull. This marine growth means extra resistance and more consumption. This cost will certainly weigh up on long distances. By regularly having the hull cleaned and choosing underwater hull cleaning you limit the resistance and therefore the costs. The advantage? Travel longer distances and use less fuel.

Benefit 2 - Treat the environment responsibly

The more fuel is needed, the worse for the environment. The fouling on the hull therefore indirectly results in more CO2, NOx and SOx. By having your hull cleaned regularly, you will work more ecologically conscious.

We also give you that at SRN Group we have an EcoFriendly recognition for underwater hull cleaning and propeller polishing in European waters. This license has been issued in the Netherlands and the United Kingdom.


Every day and at every location we are committed to an incident-free workplace. We minimize the environmental impact of our activities with the following core values:
