The present invention generally provides an anchor cap or a motor cap for mounting a monopod. The cap includes a navigation light power port typical of a marine vessel, such as a bass boat or speed boat. The cap would connect to the top of an anchor affixed to the marine vessel. The monopod can then provide power for mobile accessories, such as cameras and smart phones. The monopod may be fitted with extendable, bendable arms for mounting additional cameras or other electronic devices or for providing additional accessories. The box could also include other power outlets, including universal serial bus (USB) or standard power outlet ports.

Disclosed is a system and method for regenerating and distributing energy, such as employed on a vessel or floating offshore installation, the system including a first power distribution system, a second power distribution system electrically isolated from the first power distribution system, and a flywheel mechanically connected to both the first and second power distribution systems. Each of the first and second power distribution systems may include a motor/generator mechanically connected to the flywheel and a drive module electrically connected to its respective motor/generator. The flywheel drive modules may be connected to a common flywheel control module that includes a control algorithm for operating the system.

A device for establishing an electrical connection between a multiphase distribution grid of a ship and a multiphase supply grid on the land, having an electrical plug unit arranged on the ship and an electrical coupling unit arranged on the land for making electrical contact with the electrical plug unit of the ship, wherein the electrical coupling unit arranged on the land is designed to be able to be moved along at least a partial region of the ship. To create a device for establishing a land power connection of a ship that allows rapid and flexible establishment of electrical contact, it is proposed according to the invention for the electrical coupling unit on the land to be designed to be able to be moved in a manner guided by rails, wherein the electrical coupling unit on the land has a reception and guidance device for the wired plug of the electrical plug unit of the ship.

A navigation method for a ship which includes: a plurality of main generators that feed power to navigation equipment used in normal navigation and appliances for the living quarters provided within a ship body; and an emergency generator that feeds power to emergency equipment in case of fire or flood. The navigation method includes: an emergency power feeding step for feeding power to the emergency equipment using the emergency generator when at least one of the plurality of main generators is disabled due to fire or flood; and a return-to-port power feeding step for feeding power to return-to-port equipment, required for navigation for returning to port, using the main generators and the emergency generator after the fire or flood has subsided.

A marine vessel, system, and process provides for reducing or eliminating fuel consumption and emissions of marine vessels. System and method for charging an electricity storage element of an energy storage system of a floating marine vessel may include applying a power source from a marine platform to an electrical power bus of the floating vessel to charge the electricity storage element. A power generator of the marine vessel configured to supply electrical power to the power bus may be configured from an ON state to an OFF state.

An apparatus for supporting a flywheel on a floating vessel includes a support for the flywheel; and a tilt sensor for measuring an angle of slope relative to the Earth, the tilt sensor being arranged to detect a change of an angle of slope of the floating vessel relative to the Earth. The apparatus further includes a driver for manoeuvring the support relative to the floating vessel, based on the measured angle of slope from the tilt sensor, wherein the driver is operable to manoeuvre the support so as to counteract a change of an angle of slope of the flywheel relative to the Earth due to the detected change of an angle of slope of the floating vessel.
