A system for marine electricity generation and solid carbon production includes an offshore marine platform on which is mounted a regassification system for regassification of liquid methane; a methane splitting system producing solid carbon and gaseous hydrogen; and a power generation system producing electricity and exhaust heat. A first marine vessel is moored adjacent the marine platform for delivery of the liquid methane, and a second marine vessel is moored adjacent the marine platform for removal of the solid carbon produced by the methane splitting system. The hydrogen produced from the methane splitting system is used in a fuel stream for the power generation system. The exhaust heat from the power generation system is utilized in the methane splitting process. Also mounted on the marine platform is a solid carbon handling system disposed to manage the large amount of solid carbon resulting from the methane splitting process.

An autonomous body of water navigation system and method uses the current of the body of water. The body of water navigation method may be asymmetric since cargo may be transported along with the current of the body of water and the navigation system can be easily transported back up the body of water.

The present invention relates to a high voltage shore connection (HVSC) system (1) for connection of a vessel (1004) in port to electrical supply from the shore-side. The system (1) comprises a first intake (5004) comprising at least one first connecting element (3) and a second intake (5004) comprising at least one second connecting element (3), the second intake (5004) being in electrical connection with the first intake (5004). The least one first connecting element (3) and the at least one second connecting element (3) are connectable to a power supply element (4) for supplying onshore electricity. The system (1) further comprises a safety circuit element being in electrical connection with the first intake (5004) and the second intake (5004). The system (1) further comprises at least one protecting element (7) being connectable to the at least one first connecting element (3) or the at least one second connecting element (3), whichever connecting element (3, 3) not being connected to the power supply element (4). The at least one protecting element (7) comprises a safety loop being electrically connectable to the safety circuit element.

An electrical connection assembly between a movable object and a fixed installation, the assembly including the following elements of substantially cylindrical shape, centered around a vertical axis and going downwards: a windlass using a chain to move a rod along the axis; an outlet receiving a plurality of connections and provided with a hawse pipe in which the rod can engage with small clearance; a connector provided with a top endplate receiving, facing the connections of the outlet, the complementary connections; a turnable lid protecting the connections; a guide and locking system for guiding and locking the rod; and having its bottom portion of conical shape; a rod passing downwards in succession through the hawse pipe of the outlet, then the lid, in order to reach a locking system for locking with the connector; and a basket of funnel-shape, with its large opening upwards, its shape being complementary to the bottom portion of the connector, and centering the connector on the axis.

An engine device executes the control of the opening degree of a main throttle valve when engine load is in a low load area. In contrast, when the engine load is in a medium-to-high load area, the engine device sets the main throttle valve to a predetermined opening degree and executes the control of the opening degree of an air supply bypass valve.

The invention pertains to a Pacific prao-type amphidromic multihull vessel (100), comprising a hull (101) and a float (102) parallel to the hull, the float and the hull being linked by a beam (130) the hull carrying a Flettner-type rotary rigging (111, 112) capable of producing a thrust perpendicular to both its spinning axis (110) and a wind direction (180), that in absence of wind is heeled by an angle ? toward the float. The invention also pertains to a system implementing such a vessel for collecting windpower into a storage battery housed in the float as well as a method for boarding and disembarking such a battery.
