A charging system for an unmanned underwater vehicle (UUV) is disposed within a submerged docking station. The charging system includes a battery, one or more generators, and a charge controller. The battery supplies electrical power to an electrical distribution bus in the docking station. The charge controller monitors the charge state of the battery and, when needed, activates one or more of the generators to recharge the battery. The charge controller also activates one or more of the generators when a UUV is docked in the docking station for recharging of its power plant.

A method for generation of gasses contained in a salt solution in accomplished by disposing automated, floating wave power collection vessels in waters distant from shore, the vessels navigating within one or more predetermined geographic zones, having suitable wave conditions for such operation. The wave power devices generating electricity and the gasses are extracted from the salt solution by electrolysis. Automated storage vessels are used as shuttles to deliver the gasses to shore facilities.

Arrangement for providing cooling energy to a cooling medium circuit of a marine vessel having a storage of liquefied gas, the arrangement having a gas feeding system being provided with gas evaporation / heating apparatus. The gas evaporation / heating apparatus is arranged in heat transfer connection with the cooling medium circuit of the vessel through an intermediate flow circuit.

A ventilation system for a watercraft engine includes an improved construction that can inhibit oil in an oil container from flowing into an air induction system even if the watercraft capsizes. The engine includes an engine body and an air induction system that introduces air to combustion chambers. A lubrication system is arranged to lubricate at least a portion of the engine body with lubricant oil. The lubrication system includes an oil tank assembly out of the engine body. A ventilation system is arranged to separate a gaseous component from a liquid component. The ventilation system includes a separator configured to separate the gaseous component from the liquid component. A ventilation passage connects the separator with the air induction system. A return passage couples a bottom portion of the ventilation passage with inside of the engine body.

A marine vessel control system includes a primary marine propulsory mechanism attached to the vessel and an intelligent vessel control system. Also included is an attitude sensor linked with the intelligent vessel control system. An actuating system responding to an output of the intelligent vessel control system is linked with the primary marine propulsory mechanism for adjusting a trust vector of the primary marine propulsory mechanism.

The present invention relates to a cold heat recovery apparatus using an LNG fuel which recovers cold heat from the LNG fuel when an evaporated gas from a liquefied gas is re-liquefied as cargo to reduce costs required for installing and operating a re-liquefying apparatus and reduce energy consumption and environmental pollution materials without consuming additional energy in a re-liquefying process, and to a liquefied gas carrier including the same. According to the present invention, the cold heat recovery apparatus, which uses cold heat from an LNG fuel to treat the evaporated gas generated in a liquefied gas tank, includes a cold heat usage unit that uses the cold heat from an LNG, which is supplied as fuel from the LNG fuel tank, which stores LNG, to an engine, to treat the evaporated gas generated in the liquefied gas tank.

A system and method for orienting first and second reaction turbines relative to an axis of rotation responds to a fluid flow having a flow orientation axis. The fluid flow is received in a casement. The casement has first and second endplates situated parallel and spaced apart along the axis of rotation. A first half of the fluid flow drives the first reaction turbine to rotate with a first spin orientation in a plane perpendicular to the axis of rotation to produce a first torque about the axis of rotation. The second half of the fluid flow drives the second reaction turbine, offset from the casement plane relative to the first reaction turbine, with a second spin orientation opposite the first spin orientation to produce a second torque about the axis of rotation. The casement is oriented about the axis of rotation in response to the first and second torques.

A floating LNG storage and re-gasification unit, which comprises a LNG storage tank (2), a power plant (3), and a vaporizing unit (5), which power plant is arranged to generate heat for the vaporizing unit. The power plant (3) comprises a number of heat sources, which are connected to a single heating circuit (4). In order to increase the overall efficiency of said unit, the single heating circuit is directly or indirectly connected to the vaporizing unit (5).

A device for charging at least one electric battery (1) on board a boat comprises a propeller (2) adapted to immersed in water through the movement of the boat be driven to rotate a axle (3) and an electric direct current machine (8) connected to the axle and adapted to generate voltage to the battery for charging thereof upon rotation of the axle. A DC / DC-converter (7) is arranged to convert the voltage generated by the electric machine through the rotation of the axle to a higher voltage suited for charging the battery. A member (10) is adapted to measure the voltage generated by the electric machine and a micro processor unit (9) is adapted to control the DC / DC-converter on the basis of voltage data delivered by said member.

Disclosed is an improved ventilator apparatus for covers. The apparatus comprises a dome section that is associated with a first ventilator plate on the outside of a vehicle cover. The Dome section extends through the vehicle cover where it is associated with a second ventilator plate. A nut is used to releaseably associate the component pieces together so that a portion of the vehicle cover is clamped between the first ventilator plate and the second ventilator plate. Both the first ventilator plate and second ventilator plate are interchangeable so that either plate may be used on the inside or outside of the cover.

A system that incorporates teachings of the subject disclosure may include, for example, a water vehicle including a deck that accommodates a group of passengers above a waterline and an observation gondola accommodating the group of passengers below the waterline. The access between the observation gondola and the deck is provided by way of an aperture in a top of the observation gondola. The observation gondola includes a transparent floor and walls allowing the group of passengers to enjoy an underwater experience without exposure to the water and while maintaining an unobstructed panoramic view of the underwater environment. The underwater observation gondola can include a substantially open top, which may include a sun screen or weather protective cover. The open top exposes the observation gondola to fresh air, while alleviating any claustrophobic sensations as might otherwise be experienced by passengers during underwater observation. Other embodiments are disclosed.
