摘要： The present invention seeks to reduce the frictional resistance of a vessel through enhanced air lubrication by creating and sustaining a superaerophilic surface underneath the vessel. Air is supplied by two different means: through vents near the bow of the vessel and through the perforated superaerophilic surface underneath the vessel. The air delivered through the perforations in the superaerophilic surface prohibits wetting of microscopic structures on the surface, maintaining the superaerophilic properties of it. Since the superaerophilic surface attracts air close to the hull surface, this invention greatly increases the ratio of air from the bow vents within the boundary layer, improving the efficiency and effectiveness of the air lubrication system. Aerophilic effects are enhanced by carbon, which is captured, filtered, and mixed in with the air supplied to the plastron.

摘要： A computer implemented method of monitoring the cleanliness of an underwater surface of a stationary object. The method is performed on a computing device and comprises: retrieving environmental data from memory of the computing device, the environmental data associated with environment conditions of the stationary object; determining a fouling value indicative of a level of fouling that the surface is exposed to based on at least the environmental data; determining a fouling protection value defining a tolerance to fouling associated with a surface of the stationary object; and identifying a level of risk of fouling on the surface of the stationary object by determining a fouling risk value using the fouling protection value and the fouling value.

摘要： A movement device is for progressive movement on the surface of a body around which a fluid passes, such as a hull, a rotor blade, a rudder, a tubular body or the like. The movement device has a retaining system for adhesion of the movement device on the surface, a traction system for providing a course for the movement device on the surface, and a drive system for driving the movement of the movement device on the surface. The drive system has at least one flow element, around which flow can pass, for interaction with the fluid, such that, for the progressive movement of the movement device on the surface of the body around which the fluid passes, flow energy can be extracted from the fluid passing around it and can be used for driving the movement.

摘要： The invention discloses a method for preparing an anticorrosive surface layer of a metal material in a marine environment by laser, which belongs to the technical field of laser processing. First, the laser cladding method is used to prepare a cladding surface layer on the surface of the metal material that is not easy to undergo chemical substitution reaction with the chlorides (NaCl, MgCl2 , CaCl2 etc.) in the seawater. Then, on the surface of the cladding surface layer, ultrafast laser processing is used to form a surface layer with a wetting angle (and water) greater than 90 degrees and with hydrophobic characteristics.

摘要： The method and system uses ultrasound (US) transducers in contact with an inboard surface underwater portions of marine vessels or structures. By first digitally generating disruptive, multi-frequency, interfering US waveform signals (complex waveforms, typically replicating a Bessel function) and then converting the signals into analog, the transducers generate disruptive, multi-frequency, interfering US waveforms through the underwater portions of the marine vessels and structures which waveforms disrupt unwanted marine growth on the water-side of the vessel or structure. The digital signals, and also the analog signals, are complex waveform signals, typically produced with a Bessel function. The US transducers are either circular membrane transducers or surface transducers. A computer processor coupled to a memory, generates the complex waveform signals fed to the US transducers.

摘要： An antifouling layer stack comprising a first layer element, a silicone layer, and a second layer element. The silicone layer is a light guide for UV radiation, and may include embedded UV light sources. The first layer element is situated on a first surface of the silicone layer, and the second layer element is situated on a second surface of the silicone layer. The first and second layer elements differ in composition from the silicone layer. The first layer element facilitates transmission of the UV radiation from the silicone layer to an external medium, and may provide protection and improve the structural integrity of the stack. The second layer element may also provide protection and structural integrity. The second layer element may be reflective, and may provide an adhesive surface for attaching the stack to a vessel.
