Offshore wind energy infrastructures require effective and sustainable scour protection to ensure monopile stability and minimize environmental impact. Traditional systems, though hydraulically stable, lack ecological integration. Nature-Inclusive Scour Protection Systems (NISPS) address this gap by combining structural integrity with biodiversity promotion. This study evaluates the performance of a specific NISPS from ECOncrete, called Droplock, through physical modelling at a Froude scale of 1:30. Experimental testing was conducted at the Coastal & Ocean Basin (COB) in Belgium and in a first stage at ECOREL in Spain. Tests included cumulative and non-cumulative wave loading on soft and hard seabed, with configurations with 0%, 30%, and 50% of the units being alternatively sized, mixed with normal-sized Droplock units. Results demonstrate the feasibility of application of the tested NISPS around a monopile.
