<p>The increasing threat of tsunamis to coastal populations and strategic naval infrastructure highlights the need for enhanced coastal protection measures. In parallel, offshore floating platforms, deployed for oil and gas exploration are also being focused as potential sources of wave and wind energy harvest. The current study integrates the functional objective of coastal protection with energy harvesting in the design of a multi-functional, bio-inspired floating offshore platform, TSUSUCA-DOLPHIN^Patented. The geometric design is to serve as a tsunami barrier when provided in parallel units while the primary function is to serve as a wave energy converter. In addition, the bio-inspired geometry enhances its appeal as a tourist attraction, enabling its use as a training center for sea sickness under normal sea conditions. The conceptual design and working mechanism of TSUSUCA-DOLPHIN^Patented are discussed in the paper, and its dynamic response is evaluated through numerical simulations. The platform's response to heave and pitch modes is analyzed to demonstrate its dual functionality in energy harvesting and coastal protection. This study provides a preliminary framework for developing multi-purpose offshore platforms that offer energy extraction, coastal defense, and recreational opportunities.</p>
