Abstract

In this research the hydrodynamic stability of a ballast filled mattress under waves is investigated. There is checked if this can be applied as scour protection around a suction bucket jacket: an offshore wind turbine foundation that uses a vacuum to suck itself in position. A ballast filled mattress is a mattress made from polyester with so called spacer threads that take up tensile forces when the mattress is trying to deform. The combination of stiffness and combined weight make the ballast filled mattress a possible new scour protection.
