1. A tuned mass damper (TMD) system in combination with a floating offshore wind turbine (FOWT) platform comprising:
a barge FOWT platform having a hull configured to have a wind turbine tower mounted thereon; and
a TMD system mounted in the hull, the TMD system having:
a first TMD configured to operate at a first frequency; and
a second TMD configured to operate at a second frequency different than the first frequency;
wherein the first TMD includes a first water ballast chamber that defines a mass of the first TMD, and wherein the second TMD includes a second water ballast chamber that defines a mass of the second TMD.
