Maneuvering in Shallow and Confined Water

Abstract: The maneuvering characteristics are highly affected by the under‐keel clearance. In shallow water, the results of standard maneuvers reveal a decreased maneuverability and an increased straight‐line stability. This modified behavior is mainly to be ascribed to the modified flow around the hull, but also the control forces exerted by rudder and propeller are different compared to the deep‐water case. Besides the effect of vertical limitations, a ship navigating parallel to the horizontal boundaries of navigatio… Show more

“…The environmental data also include the bathymetry/depth profiles (EMODnet Bathymetry - The European Marine Observation And Data Network, 2018) that cover the whole AOI, with a spatial resolution of m in both longitudinal and latitudinal directions. The bathymetric profiles are used to identify the shallow water areas characterised by reduced manoeuverability (Vantorre et al., 2017). The scenario considers a typical multi-role patrol frigate with the properties defined in Table 3.…”

“…The weather routing system also requires knowledge of the bathymetry or depth profile over the AOI to delimit the areas where the navigation is not allowed or difficult (e.g. identification of shallow water areas characterised by reduced manoeuverability (Vantorre et al., 2017) or risk of grounding).…”

“…These METOC variables are used in the proposed system. Finally, the bathymetry or depth profile (d [m]) over the selected AOI is also used in the proposed system to identify the areas where ship navigation and maneuverability are limited or not allowed (due to the shallow water effect [13] or not enough under keel clearance). The availability of high-resolution bathymetry data allows us the estimation of more accurate λ when this is not available from the local or remote provider.…”

“…The proposed framework uses the Hunt's method [14] characterized by an approximation error of the order of 0.1% in the entire range of depth values. Furthermore, the bathymetry represents an important parameter for the identification of the shallow water areas characterized by reduced maneuverability [13].…”
