I 



(iv) Where the Administration would require a rudder stock with a 

 diameter in way of the tiller exceeding 9 inches (or 22 86 centimetres) there 

 shall be provided an alternative steering station located to the satisfaction of 

 the Administration. The remote steering control systems from the principal 

 and alternative steering stations shall be so arranged to the satisfaction of the 

 Administration that failure of either system would not result in inability to 

 steer the ship by means of the other system. 



(v) Means satisfactory to the Administration shall be provided to enable 

 orders to be transmitted from the bridge to the alternative steering station. 



(c) Cargo Ships only 



(i) The auxiliary steering gear shall be operated by power in any case 

 in which the Administration would require a rudder stock of over 14 inches 

 (or 35 -56 centimetres) diameter in way of the tiller. 



(ii) Where power operated steering gear units and connections are fitted 

 in duplicate to the satisfaction of the Administration, and each unit complies 

 with sub-paragraph (iii) of paragraph (a) of this Regulation, no auxiliary 

 steering gear need be required, provided that the duplicate units and connec- 

 tions operating together comply with sub-paragraph (ii) of paragraph (a) of 

 this Regulation. 



Regulation 30 



Electric and Electrohydraulic Steering Gear 



{a) Passenger Ships and Cargo Ships 



Indicators for running indication of the motors of electric and electro- 

 hydraulic steering gear shall be installed in a suitable location to the 

 satisfaction of the Administration. 



(b) All Passenger Ships {irrespective of tonnage) and Cargo Ships of 5,000 

 Tons Gross Tonnage and upwards 

 (i) Electric and electrohydraulic steering gear shall be served by two 

 circuits fed from the main switchboard. One of the circuits may pass through 

 the emergency switchboard, if provided. Each circuit shall have adequate 

 capacity for supplying all the motors which are normally connected to it and 

 which operate simultaneously. If transfer arrangements are provided in the 

 steering gear room to permit either circuit to supply any motor or combination 

 of motors, the capacity of each circuit shall be adequate for the most severe 

 load condition. The circuits shall be separated throughout their length as 

 widely as is practicable.
