Abstract
The present disclosure provides a disk for reducing scour around a pile, such as a monopole, installed in the seabed. The disk has a pile opening through which the pile protrudes. The disk includes a peripheral skirt for embedding into the seabed below the portion of the disk installed above the seabed. The disk can include partitions for segmenting chambers of the disk. The disk can include mesh on the top, bottom, or both surfaces with one or more fill bags installed in the chambers. The disk can include chambers that can be filled with fluidized fill material, such as grout or concrete. The fill material can be inserted into the fill bags through conduits with valves that can be remotely operated with an ROV. The fill material can also be injected below the disk using the conduits for support on the seabed.
