Offshore and ship technology

Sensors that defy the elements

The demands placed on the technology involved in offshore and ship technology are enormous. Among other things, heavy loads must be moved, propellers adjusted, stabilizers controlled and the course maintained. And all this in an occasionally harsh climate at sea. Hydraulics are superior to other solutions when it comes to these challenges. But to be superior, they need the right sensors. Reliable and robust technology from Balluff withstands strong winds, high seas and aggressive salt water.

Application examples

  • Compensate for wave movements

    For safety on the high seas

    The solution

    Intelligent hydraulics with our triple-redundant BTL magnetostrictive linear position sensor compensates for all boat swaying. Even in heavy seas, people from the supply vessel can safely reach the platform or the offshore wind power plant.

    The features

    • Maximum safety through redundancy
    • Rule-compatible and therefore perfectly suitable for complex control

  • Lifting loads

    Reliable end position detection for safe operation at sea

    The solution

    Cranes are used at sea for heavy loads. For reliable operation, hydraulics and sensors attuned to the harsh seas are necessary. Our explosion-proof inductive sensors reliably detect the end position of the offshore crane. In doing so, they make work safer.

    The features

    • High-pressure resistant (up to 500 bar)
    • High temperature versions are available
    • Wide portfolio for installation in every cylinder type
    • Reliable, even at high seas

  • Controlling variable pitch propellers

    The critical advantage for the ship propulsion system

    The solution

    Variable pitch propellers bring critical advantages to the ship propulsion system. This is particularly worthwhile when there are frequently changing speeds, such as on ferries or cruise ships. Angle adjustment is hydraulic and is controlled by our triple-redundant BTL magnetostrictive linear position sensor.

    The features

    • Easily retrofit safety – compatible with the standard BTL
    • status LED, 3x
    • GL approval (Germanischer Lloyd)
    Monitor the variable pitch propellers of the ship propulsion system

  • Ensuring maneuverability

    Control reliably, even under difficult conditions

    The solution

    Jet drives are used for high speeds at heavy seas or for maneuverability when traveling slowly. Hydraulic cylinders inside them move the infeed flap and nozzle to adjust to direction and speed. Our BTL magnetostrictive linear position sensors, which are fully integrated into the cylinders, reliably measure these movements, thereby ensuring maneuverability.

    The features

    • Can be completely integrated into the cylinder
    • Resistant stainless steel
    • Accessories for the pass-thru of the cable through the cylinder are available (stainless steel, IP67)
    Ensure maneuverability at heavy seas

  • Adjusting ship rudders

    Correct course by monitoring the rudder position

    The solution

    Balluff position measurement technology makes it possible to continuously adjust the rudder so that a ship is kept on course. Our BTL rod and BTL profile magnetostrictive linear position sensors continuously monitor the position of the rudder, which can then be readjusted if necessary.

    The features

    • Contact-free
    • BTL rod: Protected by integration into the cylinder
    • Rod or profile housing

  • Controlling ship stabilizers

    Reliable against ship movements

    The solution

    Heavy seas present a problem for many passengers, especially when it comes to cruises. Stabilizers minimize ship movements. Depending on the position, the optimal fin angle is changed to keep the ship as vertical as possible in the water. Our BTL HB magnetostrictive linear position sensors reliably guarantee the correct adjustment of the angle.

    The features

    • Watertight, IP69K
    • Connector with protective sleeve device
