Hydraulic retractable / height-adjustable and tiltable rudder propellers

Are you looking for a system that will allow you to sail in shallow water without any worries? Or in areas with a lot of fluctuation in water depth? Do you want to be able to easily adjust the height of the propeller to the load factor? Or do you need a system that is resilient if the unit is grounded? In all these cases, a retractable rudder propeller is the ideal solution.

The hydraulic height-adjustable Hydro-Armor units combine the properties of a ‘retractable’ system particularly with the advantages of a hydraulic rudder propeller.

Please see below video for a short animation of the advantages.

The advantages of hydraulics

Significant cost savings. Cheaper to purchase, cheaper to maintain and repair.
Less damage. No bevel gears, no drive shafts, special seal system. Equipped with shear pins, very solid construction, even suitable for Arctic conditions.
Shorter delivery times. Thanks to an advanced production process and ample stock.
Simple, quick and easy to assemble. Plug-and-play system, assembly without alignment. Can be installed at any height, even entirely submerged in water.
Choose for yourself where to install the engine.
Greater flexibility on-board. Besides the propeller, with a hydraulic power pack you can also power other systems, such as a crane, a winch or even a generator. As a result, you need fewer diesel engines to do the same thing.
Optimal manoeuvrability. From full steam ahead to full astern in 2 seconds. Quick steerage, ideal for dynamic positioning.
Super-compact, good performance, low noise level, can also run on bio-oil

The advantages of a retractable system

Prevent damage. With the depth adjustment system, you can easily adjust the height of the propeller to differences in water depth or load.
Optimise performance. Better performance and lower fuel consumption due to optimal water flow.
Fully retractable. Even if the ship runs completely dry, the propeller remains undamaged.

The advantages of a tiltable system

Easy to maintain. Dirt or rope in the propeller? Damage? Because you can tilt the propeller, you do not need the services of a diver or dockyard. This saves you a lot of time and money.
Easy to operate. The propeller is tilted with the press of a button.
Secure with sheer pin system. If you hit something, then the safety pins will break and the propeller will automatically tilt upwards. This prevents any damage.
