Abstract:
The invention relates to an arrangement for improving load response in a marine vessel, which vessel comprises a propulsion system (1) including an internal combustion engine (2), a generator (3), a main switchboard (4), and an electric propulsion unit (5). A power bank (6) is connected to the main switchboard (4), whereby the power bank (6) is arranged to store additional electric energy supplied by the generator (3) by way of the main switchboard (4). The additional energy stored in the power bank (6) is arranged to be used together with the electric energy supplied by the generator (3) in order to increase the load response to the electric propulsion unit (5) at a given time.
Abstract:
A propulsion system for a marine vessel is provided with at least one skeg in its hull and with a first propulsion device provided at the stern area of the vessel for providing propulsion power. A second propulsion device is located in connection with the skeg and comprises a system for changing the direction of its thrust effect.
Abstract:
A marine vessel includes a hull and has at least one load carrying facility defined by at least one loading space with a given height, a given width and a given length, whereby the loading space is provided on a bulkhead deck, and a propulsion arrangement, which includes at least one steerable thruster unit connected by a shaft arrangement to a drive means. In order to provide better access to the bulkhead deck for loading and unloading the marine vessel, the steerable thruster unit is arranged below the bulkhead deck and the drive means is arranged above the loading space. The shaft arrangement comprises a substantially vertical shaft section extending from the drive means above the loading space through the given height of the loading space and to the steerable thruster unit below the bulkhead deck.
Abstract:
A marine vessel has at least two engines installed in separate respective engine compartments that are positioned substantially horizontally adjacent to each other and are separated from each other by a wall structure defining at least one opening provided with a floodgate arrangement. The floodgate arrangement includes a gate device that is movable between a closed position, in which the gate device blocks the opening, and an open position, in which the gate device frees the opening, and a buoyancy assisted movement actuation device for moving the gate device from its closed position to its open position under the influence of rising water level.
Abstract:
A marine vessel power generation system comprising a conventional machinery arrangement, such as an internal combustion engine (2) and a generator (3), a propulsion system, and a main switchboard (6). In order to provide an environmental friendly power generation system, when the marine vessel enters, leaves or is in port, said system is provided with an H2O operated power generation arrangement (8) for generating H2O from seawater in order to produce electrical energy.
Abstract:
The invention relates to a marine vessel comprising a hull and a propulsion arrangement. The marine vessel is further provided with at least one vertically arranged cylinder (6) with a cylindrical shell and with a first vertical axis (7). The vertically arranged cylinder is adapted to rotate around the first vertical axis. In order to provide a flexibly adaptable arrangement suiteable for various operating modes of the marine vessel, the cylindrical shell comprises at least three sections (62, 63, 64) with a curved portion extending between two ends, whereby each of the three sections is arranged to be turnable around a respective second vertical axis (8), which is positioned at the circumference of the cylindrical shell. Each section is arranged to be anchored into a given position.

Abstract:
The invention relates to a marine vessel with at least a first cargo facility at a stern end and at least a second cargo facility at a bow end, and having a deckhouse arranged between the first cargo facility and the second cargo facility. In order to provide for cost-effective propulsion and cargo transport in combination, the propulsion system comprises a first propulsion unit and a second propulsion unit forming a CRP propulsion system. The machinery of the first propulsion unit and the machinery of the second propulsion unit are located on top of each other under the deckhouse.
