A mobile waterborne energy platform systems and methods comprising a purpose built marine vessel, a pre fabricated building structure, a plurality of fuel cells or generators, a plurality of fuel tanks, a plurality of mechanical equipment, a plurality of electrical equipment and a method to transmit electrical power to shore or to another marine vessel. The mobile waterborne energy platform systems and methods described may be employed to quickly provide utility grade electrical power to remote austere locations. The electrical power may be produced by a plurality of fuel cells or generators configured on a mobile waterborne vessel that may be transported to remote areas to provide an on site electrical power source for critical infrastructure, communications, emergency or medical facilities. The systems and methods are ideal for military purposes where troops may be deployed in remote locations without readily available utility grade electrical power.

A situation display device is provided. The device includes: an observation data acquiring module configured to acquire observation data, and information of observed locations of the observation data; a data selecting module configured to select the observation data within a predetermined range from a course of the device; and a display unit configured to display a location of the device on a bottom side of a display screen, and display the course linearly such that its traveling direction extends upward from the bottom side. The display unit displays, a predetermined area in an upward tapering shape, and displays the selected observation data at a position that indicates a relation between the course and the observed location, the displayed position of the device in the perpendicular direction being corresponding to an offset of the location of the device from the course.

Systems and methods for dockside regasification of liquefied natural gas (LNG) are described herein. The methods include providing LNG from a LNG carrier to a regasification vessel. The LNG may be regasified on the regasification vessel. The regasified natural gas may be discharged with a high pressure arm to a dock and delivered onshore. The regasification vessel may be moored to the dock. The LNG carrier may be moored to the regasification vessel or the dock.

An ultrasonic system for treating a submerged surface of a target structure, the system including: an ultrasonic generator for generating electrical energy to drive first and second ultrasonic transducers, the electrical energy including at least two different frequencies including a first and second operation frequency; first ultrasonic transducers configured to be mounted as a first array to the target structure, and connectable to the ultrasonic generator and operable to generate a first ultrasound signal from the first operation frequency; and second ultrasonic transducers configured to be mounted as a second array to the target structure, and connectable to the ultrasonic generator and operable to generate a second ultrasound signal from the second operation frequency, wherein the first and second ultrasonic transducers are spaceable from one another to produce guided ultrasonic waveforms through the target structure including heterodyned frequencies from the first ultrasound signal and the second ultrasound signal.

A sea water intake riser system for a floating production unit, including a caisson having a through-opening in a bottom side and being connectable to an upper end of a riser pipe; a lift pump inside the caisson and having an inlet at a vertical distance with a predetermined minimum submergence for pumping cold water from the caisson up to the floating production unit for use as cooling medium, wherein the sea water intake riser system includes at least two caissons, having a height substantially equal to a vertical height of a hull of the floating production unit and including an open top side; each caisson extending from a predetermined minimum distance from the bottom side of the hull up to at least the water-line during use and wherein a sump tank is located between the bottom side of the hull and the at least two caissons.

A marine vessel advisory system may be configured to calculate and provide operational information that show fuel consumption savings based on adjustment of vessel speed and/or heading. In an embodiment, the advisory system may operate real-time to collect operational and/or environmental conditions information to be used to calculate alternative operational performance of the marine vessel that will save fuel and reduce emissions. The calculations may include a simulation, machine learning, and/or artificial intelligence to determine a speed and/or heading of the marine vessel that will reduce fuel consumption. The advisory system may display the computed information for the operator, and the operator may elect to switch to the alternative operating parameters (e.g., slower speed). In an embodiment, the advisory system may interact directly with a marine vessel system and automatically cause the marine vessel system to adjust operating parameters based on computed operating parameters that saves fuel and reduces emissions.

An apparatus and method of measuring, monitoring, recording and verifying the uptake and discharge of ballast water on marine vessels to ensure that they comply with the ballast water discharge standards set by international bodies, the apparatus includes an arrangement of small sampling pipes, valves, sampling pump, flow meter, Ballast Water Monitor, Ballast Water Sensors Module and Controller. The method comprises measuring the concentration of the bacteria and pathogens in the sampled ballast water during ballasting and de-ballasting by the Ballast Water Monitor and compared against the regulatory standards and historical data of similar ship data and ballast water data. The method also identifies and isolates specific ballast water tank that holds non-compliant ballast water so that when compliant water is available, the non-complaint ballast water shall be flushed out from the identified specific ballast water tank with the compliant water. All information are saved in a secure, tamper-proof and encrypted format so that they are verifiable and traceable to ensure that no non-compliance ballast water has been discharged overboard at ports at all times.

A system and a method are for heat treatment of water of a vessel outside a fixed installation of the vessel. The water includes ballast water of the vessel and/or waste water from hull cleaning of the vessel. The system includes a system inlet; a system outlet; a heat application section; and a heat treatment piping system. A heat recovering section includes two parts for exchanging heat. The heat treatment piping system couples the system inlet to the system outlet via: one of the parts of the heat recovering section, the heat application section and the other part of the heat recovering section. The system does not form part of a fixed installation of the vessel.

A system includes an unmanned underwater vehicle (UUV), a reaction structure configured to deploy from a body of the UUV, and one or more tendons connecting the reaction structure to the body of the UUV, wherein the reaction structure deploys at a depth below the body of the UUV.
