Anchors of bull kelp protect it from torque by being flexible.

BIOMIMICRY TAXONOMY
Summary
"Kelp’s survival depends on flexibility and extensibility. Each alga can grow up to 20 to 45 m (22 to 49 yd) long and consists of a holdfast, stipe, float, and fronds. The holdfast uses a flexible network of root-like haptera or anchors to attach the kelp to the ocean floor. By being flexible, the haptera allow the kelp’s base to rotate slightly, thus providing some protection from the high torque created by waves." (Biomimicry Guild unpublished report)

Much could be learned by comparing this biomimicry strategy, point-by-point to the vastly different, but highly developed, technologies used to stabilized off-shore oil drilling structures.
