Abstract: According to an embodiment of the disclosure, a vessel includes a hull structure, a foundation, a plurality of springs, and plurality of hydraulic jacks. The hull structure is configured to float on water. The foundation is mounted on top of the hull structure and has significant mass. The foundation is configured to support a turbine structure and to absorb at least a portion of the forces or kinetic energy from the turbine structure. The plurality of springs are positioned between the hull structure and the foundation. The plurality of springs are configured to isolate the foundation from the effects of deflections in the hull structure, to absorb at least a portion of the forces or kinetic energy transferred from the turbine structure, and to transfer at least another portion of the forces or kinetic energy from the turbine structure to the hull structure.
