Steering Gear · Steering Gear
On a vessel, steering equipment is normally installed in the steering-gear compartment and transmits helm commands to the rudder or other steering actuator through hydraulic, electrical or electro-hydraulic equipment. Safe steering depends on duplicated or redundant power arrangements where required, intact hydraulic or electrical circuits, reliable feedback and functional local and remote controls. The system must remain controllable after relevant single faults in accordance with the vessel design and applicable class or statutory requirements. The M50 designation distinguishes this entry from neighbouring Kongsberg Maritime AS products, but actuator type, capacity, redundancy and control architecture should not be inferred without the exact product documentation. Refer to the manufacturer and vessel steering-gear documentation for exact operating pressures, rudder limits, alarm settings and test criteria.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect pumps or drives, actuators, hydraulic piping where fitted, foundations, mechanical linkages, feedback devices, local controls and emergency steering arrangements. Check for leakage, loose fasteners, abnormal play, contamination and signs of overheating. Function-test main and alternative steering controls, alarms, power-failure response and changeover arrangements using the approved vessel procedure. Survey attention includes redundancy, emergency operation, rudder-angle indication and evidence that defects are repaired rather than masked by bypasses. Refer to class, statutory and manufacturer documentation for exact test criteria.
Useful spares include seals, filters, control relays, solenoids, feedback or limit sensors, fuses, contactors and service items for the installed pumps or drives. Critical hydraulic and control parts must be matched to the exact steering-gear build and approved redundancy arrangement.
