[接上页] (a) two steering gear control systems shall be provided, each of which shall be capable of being operated separately from the navigating bridge. Duplication of the steering wheel or lever is not required; (b) in the event of failure of the steering gear control system in operation, the other system shall be capable of being brought into immediate operation from a position on the navigating bridge; (c) each steering gear control system, if electric, 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; (d) in the event of failure of electrical power supply to a steering gear control system, an alarm shall be given on the navigating bridge which shall be audible and visual and situated where it can be readily observed; (e) means for control of the main steering gear shall be provided in the steering gear compartment; (f) means shall be provided in the steering gear compartment to disconnect the steering gear control system from the steering gear it serves; (g) means of communication shall be provided between the navigating bridge and the steering gear compartment; (h) the rudder angle indication system on the navigating bridge shall be independent of the steering gear control system; (i) the angular position of the rudder shall be recognizable in the steering gear compartment; (Enacted 1991) Cap 369R reg 41C Additional requirements - tankers of 10000 tons or over On and after 1 September 1986 in every tanker (including chemical carriers and gas carriers) of 10000 tons and over- (a) a low level alarm shall be provided for each hydraulic fluid reservoir to give the earliest practicable 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; (b) a fluid storage tank shall be provided having sufficient capacity to recharge at least one power actuating system including the reservoir. The storage tank shall be permanently connected by piping in such a 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; (c) the steering gear compartment shall be provided with suitable arrangements to ensure working access to the 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. (Enacted 1991) Cap 369R reg 41D Additional requirements - tankers of 40000 tons or over On and after 1 September 1988, in every tanker (including chemical carriers and gas carriers) of 40000 tons and over the steering gear shall be so arranged that, in the event of a single failure of the piping or of one of the power units, steering capability can be speedily regained. This shall be achieved by- (a) an independent means of restraining the rudder, or (b) fast acting valves, which may be manually operated, to isolate the actuator or actuators from the external hydraulic piping together with a means of directly refilling the actuators by a fixed independent power-operated pump and piping system, or (c) an arrangement such that, where hydraulic power systems are interconnected, loss of hydraulic fluid from one system shall be detected and the defective system isolated either automatically or from the navigating bridge so that the other system remains fully operational. (Enacted 1991) Cap 369R reg 41E Additional requirements - tankers of 10000 tons or over (1) The provisions of this regulation shall apply to every tanker (except chemical tankers and gas carriers) of 10000 tons or over; (a) for which the building contract was placed after 1 June 1979; or (b) in the absence of a building contract, the keel of which was laid or which was at a similar stage of construction after 1 January 1980; or (c) the delivery of which was after 1 June 1982; or (d) which has undergone an alteration or modification of a major character; (i) for which the contract was placed after 1 June 1979; or (ii) in the absence of a contract, the construction work of which was begun after 1 January 1980; or (iii) which was completed after 1 June 1982.(2) The main steering gear shall comprise two or more identical power units and it shall be capable of operating the rudder as required by regulation 32(2)(b) while operating with one or more power units. As far as reasonable and practicable, the main steering gear shall be so arranged that a single failure in its piping or in one of the power units will not impair the integrity of the remaining part of the steering gear. All mechanical components which are part of the steering gear and the mechanical connection with any steering gear control system, if any, shall be of sound construction. |
