The case
A pipe on the seabed does not move “a little more” as the waves grow. It stays put until the hydrodynamic force reaches the friction the seabed can offer. In this section model (30 in flooded pipe, 4 m of water), a 1.0 m wave uses 43 % of the available grip; a 2.0 m wave makes it walk about 0.44 m with every wave.
