Drydocks are the only time in the service life of a ship when maintenance can be done on the paint coat of the underwater part of the ship.
This process consists of a couple of steps, captured in the pictures below:
When the ship comes out of the water, we usually find some marine growth on the hull, such as the green algae you see in the picture above. In a worse state you might also find barnacles on the hull. First step is the removal of all this growth using pressure washers.
When the ship is pressure washed, it is clear that especially the front part of the ship has almost no paint left.
To ensure that the new paint will stick properly to the hull, it is now extreme high pressure washed to remove the remaining paint.
A full coat of primer is applied.
After the first coat of primer, a second layer is applied. This is special paint that is needed for the application of the silicone paint that will be applied next.
Silicone paint has an extremely low friction with the water, so the Veendam moves through with less resistance and burns less fuel.
This pink coat is a bonding layer for the final silicone paint. As soon as this layer is applied, we have only four to 10 hours to apply the silicone. The two layers merge
and form the final smooth layer.
