NEW CLASS B, C AND D SHIPS:

Steering gear control shall be provided: for the main steering gear, both on the navigating bridge and in the steering compartment; when the main steering gear is arranged in accordance with paragraph .4, by two independent control systems, both operable from the navigating bridge. This does not require duplication of the steering wheel or steering lever. Where the control system consists of an hydraulic telemotor, a second independent system need not be fitted; for the auxiliary steering gear, in the steering gear compartment and, if power-operated, it shall also be operable from the navigating bridge and shall be independent of the control system for the main steering gear. Any main and auxiliary steering gear control system operable from the navigating bridge shall comply with the following: if electric, it shall be served by its own separate circuit supplied from a steering gear power circuit from a point within the steering gear compartment, or directly from switchboard busbars supplying that steering gear power circuit at a point on the switchboard adjacent to the supply to the steering gear power circuit; means shall be provided in the steering gear compartment for disconnecting any control system operable from the navigating bridge from the steering gear it serves; the system shall be capable of being brought into operation from a position on the navigating bridge; in the event of a failure in the electrical power supply to the control system, an audible and visual alarm shall be given on the navigating bridge; and short-circuit protection only shall be provided for steering gear control supply circuits. The electrical power circuits and the steering gear control systems with their associated components, cables and pipes required by this regulation and by Regulation 7 shall be separated as far as is practicable throughout their length. A means of communication shall be provided between the navigating bridge and the steering gear compartment or alternative steering position. The angular position of the rudder(s) shall: if the main steering gear is power operated, be indicated on the navigating bridge. The rudder angle indication shall be independent of the steering gear control system; be recognisable in the steering gear compartment. Hydraulic power-operated steering gear shall be provided with the following: arrangements to maintain the cleanliness of the hydraulic fluid taking into consideration the type and design of the hydraulic system; a low-level alarm for each hydraulic fluid reservoir to give the earliest practical indication of hydraulic fluid leakage. Audible and visual alarms shall be given on the navigating bridge and in the machinery space where they can be readily observed; and a fixed storage tank having sufficient capacity to recharge at least one power actuating system including the reservoir, where the main steering gear is required to be power-operated. The storage tank shall be permanently connected by piping in such manner that the hydraulic systems can be readily recharged from a position within the steering gear compartment and shall be provided with a contents gauge. The steering gear compartments shall be: readily accessible and, as far as practicable, separated from machinery spaces; and provided with suitable arrangements to ensure working access to steering gear machinery and controls. These arrangements shall include handrails and gratings or other non-slip surfaces to ensure suitable working conditions in the event of hydraulic fluid leakage.
