📄 Abstract（原文）
Marine hydrokinetic (MHK) energy is a renewable energy source to support decarbonization and has potential resources in deep water environments, such as in the case of the Gulf Stream current. This has created a need for efficient and cost-effective anchoring solutions in deepwater, with torpedo anchors emerging as a promising option due to their simple deployment in deepwater through free-fall installation. Torpedo anchors have recently gained attention in the industry, but limited research has been dedicated towards identifying characteristics associated with improved performance in sandy seabeds. This study investigates the influence of geometric parameters including slenderness ratio (L/D) and fin length, and mass, on the penetration depth and pull-out resistance of torpedo anchors. Numerical simulations reveal that, despite their increased mass, anchors with lower L/D ratios exhibit reduced penetration due to increased frictional resistance on larger surface areas and fin-induced drag. Pull-out capacity, however, peaks at moderate L/D values, indicating an optimal balance between embedment depth and pull-out resistance. Fin length affects performance: shorter fins enhance penetration, while moderate fin lengths yield maximum pull-out. The equivalent plastic strain distribution confirms significant soil deformation near the tip and shaft. These findings provide guidance for optimizing torpedo anchors in sandy seabeds.
