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).
Claims9
A marine vessel for sea operations, comprising:
- a hull;
- a propulsion arrangement including:
- an internal combustion engine;
- an exhaust gas arrangement;
- a propulsion unit;
- and
- at least one vertically arranged cylinder with a vertical axis, said at least one vertically arranged cylinder extending generally to a same height as a vertical height of a vertical utility structure of the marine vessel, said at least one vertically arranged cylinder being adapted to rotate around its vertical axis, the at least one vertically arranged cylinder being arranged to engage with a side wind, which engages the at least one vertically arranged cylinder, which is rotated around its vertical axis by a motor in a direction of rotation, whereby a Magnus effect generates an increased pressure on one side of the at least one vertically arranged cylinder and a decreased pressure of suction on an opposite side of the at least one vertically arranged cylinder, which results in a forward trust that moves the marine vessel forward in a direction of movement of the marine vessel,
- wherein the at least one vertically arranged cylinder is arranged around a part of the exhaust gas arrangement of the marine vessel, and
- wherein the part of the exhaust gas arrangement is an exhaust pipe, and the at least one vertically arranged cylinder is arranged around the exhaust pipe, the at least one vertically arranged. cylinder provides a funnel means for the exhaust pipe, the at least one vertically arranged cylinder generates an increased pressure on one side and a decreased pressure on the opposite side of the at least one vertically arranged cylinder when the side wind engages the cylinders.
