What is Marine Propulsion ?
Hydro Armor’s hydraulic propulsion units combine manoeuvrability and propulsion.
The transmission of each thruster is a hydrostatic drive. The hydraulic drive acts as a torque converter providing unlimited propeller speed control.
The engine runs at constant speed. Depending on the power requested, the engine speed may be adjusted between 1500 and 1800 rpm. Full engine torque is available at any propeller speed. The propeller shaft is directly driven by a hydraulic motor integrated in the pod (the lower foot) of the unit.
The hydrostatic transmission pump is the powerhouse of the hydraulic system. The engine is directly driving the pump. This pump controls the thruster through variable displacement. This means the propeller speed can be accurately controlled anywhere between standstill and maximum, both forward and reverse, without altering engine speed. From full forward to full reverse in a short time.
They feature 180° steering and proportional propeller speed control in forward and reverse, providing omni directional thrust capability
MARKETS AND APPLICATIONS IN MARINE PROPULSION
Aquaculture / Fishing
Hydro-Armor thrusters are highly valued in the field of fishing and in particular for oyster and shellfish vessels, thanks to their adjustable draught.
Inland waterways
Multiple applications benefit from Hydro-Armor propulsion: passenger and freight transport, ferryboats, ferries, dredgers and service boats, towboats, etc…
Coastal shipping
Hydro-Armor propulsion is perfectly suited for inshore vessels: passenger boats, inter-island transport barges, off-shore and wind farm support, etc…
