Steering gear
조타장치
Machinery that moves the rudder in response to steering commands. SOLAS requires main and auxiliary steering arrangements, or an accepted equivalent configuration with multiple identical power units, together with prescribed controls from the bridge and steering-gear compartment.

FAMILY REFERENCE APPLICABILITY
Family profiles carrying a source marker.
Unmarked Families are not listed; an unmarked cell means “not normally fitted” in the source Family profile, not confirmed absence from a vessel.

Hydraulic pump units
유압 펌프 유닛Two independent pump sets, each able to turn the rudder alone, that supply the oil pressure moving the steering actuator.
Reference pattern · 2 × 100%View Component record →COMP-273 · ActuatorActuator (rotary vane / ram)
조타 액추에이터The hydraulic machine bolted to the rudder stock that converts oil pressure into the torque physically turning the rudder.
Reference pattern · 1View Component record →COMP-274 · Tank / VesselOil tank with level alarms
작동유 탱크·경보The steering gear's own oil reservoir, alarmed on low level because a slow leak here ends in loss of steering.
Reference pattern · 1View Component record →COMP-275 · ValveIsolating & bypass valve block
격리·바이패스 밸브 블록Valves that isolate a leaking half of the system so the remaining half keeps steering the ship.
Reference pattern · 1View Component record →COMP-276 · Instrument / SensorRudder feedback units
타각 피드백 유닛Duplicated sensors reporting the rudder's true angle back to the bridge and autopilot — without feedback there is no closed-loop steering.

현장 조타 스탠드The emergency steering position at the gear itself, with communications to the bridge, used when bridge control is lost.
