Engineering · Auxiliary — Steering Gear
Regulations require that steering-gear systems on most vessels have:
- AA single hydraulic power unit
- BA main and an auxiliary means of steering, with the ability to be brought into action rapidly✓ Correct
- CElectric drive only
- DManual hand steering as the sole backup
Explanation
Steering gear must have main and auxiliary actuating systems so that a single failure does not leave the ship unable to steer; the auxiliary must be capable of being brought into operation rapidly.
