    摘要： A watercraft with improved safety and stability is provided. The watercraft includes a shell defining a plurality of raceways for receiving water during certain maneuvers of the watercraft, thereby exerting force upon the watercraft in a first direction. The shell is configured so as to prevent or otherwise inhibit the water from exerting an opposed second force upon the watercraft. An intermediate panel of the shell provides increased flexibility, thereby serving as a shock absorber for the watercraft.

    摘要： The disclosure relates to a method of applying a coating to an external surface of a man-made object to be at least partly immersed in water (e.g. a vessel or an offshore drilling station) for a time period wherein there is relative movement between the immersed object and the water. The applied coating has a minimal resistance rating for a set of coatings. The method comprises a computer-implemented coating selection process, which comprises a first steps of obtaining, for each coating in the set of coatings, a total roughness value of the external surface based on a fouling roughness value, a macro roughness value and a micro roughness value associated with each coating. The coating selection process comprises in a second step selecting a coating from the set of coatings, wherein the selected coating has a minimal resistance rating associated with the obtained total roughness value for the time period. The method further comprises applying the selected coating to the external surface of the man-made object.

    摘要： The invention relates to a system (2) for ascertaining prediction data. The system (2) has a floating unit (4) and a remote base unit (6). The floating unit (4) has a coupling unit (8), a floating hose (10) and a detection system (12). A first end (14) of the floating hose (10) is connected to the coupling unit (8). The detection system (12) is designed to detect, as actual arrangement, a present geometric arrangement of the floating hose (10) relative to the monitoring unit. In addition, the detection system (12) is configured to detect and/or ascertain, as actual location, a present geographical location of the floating unit (4). The detection system (12) is additionally designed to ascertain actual location data which represent the actual location and the actual arrangement. The floating unit (4) is designed to transmit the actual location data via a signal link (18) to the base unit (6). The base unit (6) is designed to receive, as actual weather data, present weather data which represent the present wind strength, the present wind direction, a prediction of the wind strength and/or a prediction of the wind direction in each case of the wind at the actual location. The base unit (6) is additionally designed to receive, as actual sea data, present sea data which represent the present current strength, the present current direction, a prediction of the current strength and/or a prediction of the current direction in each case of the water at the actual location.

    摘要： A viscous-drag-reducing cladding for a ship's hull whereby the wetted area of the hull is reduced by interspersing air between the hull surface and the water. A substantial portion of the submerged area of the ship's hull comprises densely packed air pockets. The dimension of the air pocket is less than twice the capillary length of water. Each air pocket is supplied with pressurised gas by means of a restrictor. The pressurised air is supplied to each air pocket by means of a network of corrugated channels.

    摘要： The invention relates to a method for managing maintenance for a ship comprising a sealed and thermally insulating tank for transporting liquefied gas. The method comprises the steps consisting in determining 310 a current filling level of the tank, determining 320 a current state of movement of the ship, determining 330 a current sloshing index IBi from the current filling level of the tank and the current state of movement of the ship, taking into account the position and the geometry of the tank, integrating 340 the determined current sloshing index IBi into a wear index IUi that takes into account a history of the sloshing indices. The wear index is then compared to a threshold in order to indicate if the tank needs to be inspected, depending on the result of the comparison.
