A method is provided for a condition related to the activity of a protease through the administration of a -defensin, analog, or derivative is described. Suitable proteases include metalloproteases and cysteine proteases such as Cathepsin-C. The -defensin, analog, or derivative can be effectively administered parenterally, topically, or orally.

This disclosure provides wave-powered vessels equipped for fish stock management. The vessels have observational sensors for monitoring fish, a positional sensor to determine the geographical location of the vessel, and a transmitter for sending data to a central control unit. The observational sensors may be deployed on a tow body pulled behind the vessel, or the tow body may relay information from sensors located on a separate unit on the bottom or at a defined depth. The control unit communicates with each of the monitor vessels to direct navigation and obtain data from the sensors. Substance distribution vessels in the fleet are equipped to distribute fish food in target area for the purpose of fish farming.

An outboard motor includes an engine, a power generator including a rotor and a stator, a convertor, and an engine cover configured to cover the engine and the power generator. The rotor includes a permanent magnet.

A system for controlling and providing power to at least one electric motor in a vessel, such as a motor in a thruster or a winch. The system includes an electric energy storage, a power controller device connected to the electric energy storage, at least one motor controller device, a first combined power and communication line interconnecting the power controller device and the at least one motor controller device, an electric motor connected to the motor controller device, and at least one operating device connected to the power controller device. The system may further include a second combined power and communication line that interconnects the power controller device and the at least one operating device. The first combined power and communication line operates with a DC voltage level which is at least twice the operational DC voltage level of the second power and communication line.

A system for controlling a watercraft includes a data communication module, a device system, an electric power supply, and a controller. The data communication module is operable to perform wireless communication with an external computer. The device system includes at least one electric device. The electric power supply provides electric power to the data communication module and the device system. The controller is configured or programmed to switch between a first mode and a second mode. In the first mode, the controller provides electric power to the data communication module by the electric power supply during both activation and deactivation of the device system. In the second mode, the controller provides electric power to the data communication module by the electric power supply during the activation of the device system, but stops providing electric power to the data communication module by the electric power supply during the deactivation of the device system.

Example systems and methods are provided herein for providing for a controlled shutdown of a marine electronic device. Such marine electronic devices include a main unit, a power input in connection with the main unit, and a secondary unit configured to store energy for processing sonar data. The power input is configured to provide energy to the main unit, and the secondary unit is connectable to the main unit to provide stored energy to the main unit. Also included is a processor configured to determine whether the power input is providing energy within a predetermined threshold to the main unit and then, in response to a determination that the power input is not providing energy within the predetermined threshold to the main unit, cause the secondary unit to provide the stored energy to the main unit.

A vessel hybrid combined cycle power and propulsion system includes a steam turbine, a gas turbine, an auxiliary generator, an electric propulsion drive system, and an energy storage system, each connected to an AC bus. The system further includes a source of steam for the steam turbine, a control system for controlling operation of the steam turbine, gas turbine, auxiliary generators, electric drive propulsion system and energy storage system. The primary source of steam for the steam turbine is exhaust gas from the gas turbine. The primary source of gas for the gas turbine is boil off gas from the cargo hold. The AC bus includes a plurality of sections of AC bus coupled together by bus ties closed in normal operation forming a closed ring AC bus. The electric propulsion drive system includes a variable speed drive, driving an electric motor coupled through a drive shaft to a propeller.

An outboard motor includes an engine, a power generator including a rotor and a stator, a convertor, and an engine cover configured to cover the engine and the power generator. The rotor includes a permanent magnet.

A fault protection system for a power system of a dynamically positioned vessel is provided. The power system is separated into two or more power system sections, each including a bus section of a power distribution bus. The bus sections are connected by bus ties in a ring configuration. Each bus section includes a connection to a generator and a connection to a thruster drive of the dynamically positioned vessel. The fault protection system includes a fault isolation system which includes for each power system section a bus tie circuit breaker for breaking the connection provided by the bus tie.

An electrical system for a marine vessel. The electrical system includes a power supply that produces an output. A powered device is electrically coupled to the power supply, where the powered device receives an incoming power from the power supply. An analysis module determines a difference between the output of the power supply and the incoming power received by the powered device. The analysis module compares the determined difference to a first threshold and generates a first signal when the determined difference exceeds the first threshold.
