Windfarms

Fouling causes increased drag underwater. It is common that without treatment against fouling, the pilar will contain an extra 20 cm of marine growth and thus extra increase of drag and more forces on the column. Today, these forces are calculated when constructing the pillar by overengineering and using extra metal.

By using Thorn-D®, overengineering is no longer necessary and costs can be saved

Most of the traditional antifouling products are toxic. Depending on the concentration of copper the antifouling effect will last maximum 3-5 years. With respect to the offshore application area this effect is too short as infrastructural objects (e.g. locks, floating docks, bridges, platforms, etc.) and oil platforms need to be functional for an undefined period (>20 years). During this the full life span, the objects will be continuously subjected to biofouling. Guarantee of the safety of the objects is difficult without regular maintenance. Thorn-D® will significantly reduce the maintenance costs for these static objects and in addition provide it with a protective layer.

Oil platforms

Oil drilling platforms are extremely expensive structures which require a great deal of inspection and maintenance if they are to remain in a safe condition. Initially it was not thought that fouling would be a great problem and few precautions were taken against it. However, two problems have become apparent...
