According to the SOLAS rules the steering gear should be capable of being recharged with hydraulic oil from a fixed storage tank. What is the main reason for this?
To ensure that the steering gear can be rapidly recharged with clean hydraulic oil in the event of a leak from the system
Because a steady leakage of oil is to be expected from some steering gears and having a fixed storage tank reduces the time taken for topping up
