THE WAVE GENERATED BY A FINE SHIP BOW

WebA suitable bulbous bow can improve the flow field and reduce the bow bilge vortex, thus decreasing the resistance (Lu et al., 2024). Deep-water seismic survey vessels generally use a small bulbous bow to improve the bow wave. Due to the limitations of water depth, shallow-water seismic survey vessels differ from deep-water seismic survey vessels.
