Abstract
A modular hydraulic thruster system for vessel. At least one thruster is hydraulically connected to a power pack and electrically connected to an instrument panel. The instrument panel has a thrust angle indicator, tube gear clamp status indicator, extension indicator, tilt angle indicator, and tachometer, all pertaining to each thruster. The thruster includes a tube rotating and reciprocating through a housing, which is rotatably attached to a bracket. A swivel union is attached to one end of the tube; a hydraulic motor drives a propeller to an opposite end of the tube. Some instrumentation electrical and hydraulic lines are routed through the swivel union and into the tube; others are further routed out of the tube through a tube aperture and through a flexible spiral conduit to accommodate tube reciprocation within the housing. Means is disclosed to prevent a swivel union stationary section from rotating relative to the housing.
