Embodiment Construction

[0043] A propulsion system for a ship may include first and second thrust devices, each configured to generate forward or reverse thrust. The thrust devices can be operated independently such that they generate different thrusts. For example, a first thrust device may generate forward thrust, while a second thrust device may generate rearward thrust.

[0044] Water (eg thrust generated by a thrust device) may be directed laterally by guides such as rudders or nozzles. The first guide may direct thrust from a first device, and the second guide may direct thrust from a second device. The guides can be operated independently. For example, the leading edge of one director may be oriented towards starboard, while the leading edge of the other director may be oriented towards port.

[0045] The thrust from the thrusters and the angle of the lateral direction from the guides can be adjusted independently to achieve the desired combination of lateral thrust independent of longitudi...

Abstract

Various aspects provide for a propulsion system (200) for a ship (100) comprising at least first and second thrusters (205, 206) and first and second directors (220, 720), wherein a computing platform(300) is coupled to the thrusters and directors being configured to receive desired longitudinal and lateral headings (750, 760) and determine a configuration of the propulsion system that is expected to propel the ship in the desired longitudinal and lateral headings.

Description

technical field [0001] This invention relates generally to marine navigation and more particularly to ship propulsion systems capable of complex maneuvers. Background technique [0002] Boat propulsion systems typically have a propeller, screw or similar blade arrangement driven by an engine or electric motor to generate forward or aft thrust to propel the boat forward or aft. Steering and sailing requires lateral thrust usually at the stern. Rudders or nozzles can redirect water flowing longitudinally to a lateral direction, thereby changing the course of the boat. [0003] Some propulsion systems have separate components to apply longitudinal and lateral forces. A typical large boat has a fixed shaft propeller directly connected to the engine (for forward / backward thrust) and a rudder behind the propeller to generate lateral thrust. Some propulsion systems combine lateral thrust with longitudinal thrust. For example, an azimuth thruster (such as a pod-based propeller) ...
