Abstract: Disclosed is a vessel with a semi automatic or automatic vessel mooring system and a method of mooring with such a system. The vessel includes a hull, a mooring line winch unit, at least one mooring line extending from said winch unit, and a weight at an end of the at least one mooring line. A mooring line guide boom with at least one mooring line guide on a mooring line guide portion is movable between a retracted position aligned with the hull, and an extended position. In the extended position the mooring line guide boom allows the winch unit to lower the weight at the end of the mooring line extending through the mooring line guide and onto a quay.

Abstract: The invention relates to a tug for maneuvering a vessel, comprising at least one proximity sensor in a contact area, the proximity sensor being configured to detect a distance between the contact area and the vessel, and a tug controller unit controlling an approach of the tug towards the vessel based on the detected distance between the contact area and the vessel.

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 suitable 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 (1) comprising a hull (2) and a propulsion arrangement including an internal combustion engine (3), an exhaust gas arrangement (4), and a propulsion unit (5). The marine vessel (1) further is provided with at least one vertically arranged cylinder (6) with a vertical axis, which vertically arranged cylinder (6) is adapted to rotate around its vertical axis. To avoid any substantial increase of windage area, the vertically arranged cylinder (6) is arranged around a part of the exhaust gas arrangement (4) of the marine vessel (1).

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).

Abstract: The invention relates to a barge arrangement comprising a barge unit with a first end (11) and a second end (12) and a tug unit provided with a propulsion unit, which barge unit is adapted to receive the tug unit at one end. In order to achieve an efficient vessel combination for loading, transport and unloading of cargo the barge unit (102) is adapted to receive a first tug unit (2) at its second end (12) in order to be pushed by the first tug unit (2) with the first end (11) of the barge unit (1) in a forward direction (F) of motion. Further, the barge unit (101) is adapted to receive a second tug unit (3) at its second end (12) in order to be pulled by the second tug unit (3) with the second end (12) of the barge unit (1) in the forward direction (F) of motion.

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.
