### Merchant Shipping (Safety) (Cargo Ship Construction and Survey) (Ships Built On or After 1 September 1984) Regulations 《商船(安全)(貨船構造及檢驗)(1984年9月1日或之後建造的船舶)規例》

33. General
Every ship shall be provided with effective means for control of, and arrangements for monitoring the operation of, the machinery used or essential for propulsion, so that the safety of the ship in all sailing conditions, including manoeuvring is not less than that of a ship with continuously manned machinery spaces.

34. Operation and documentation
In every ship, the Certifying Authority shall ensure that the equipment provided for operating the ship with the machinery spaces containing machinery used or essential for propulsion periodically unattended, is functioning in a reliable manner before the ship is permitted to operate with those machinery spaces unattended. The Certifying Authority shall ensure that satisfactory arrangements are made for periodic inspections and routine tests on such equipment to ensure continuous and reliable operation and shall issue documentary evidence indicating that it is satisfied that the ship and its equipment is suitable for operation in the said conditions.

35. Alarms systems
Every ship shall be provided with an alarm system which shall indicate any fault in the unattended machinery or unattended machinery spaces requiring attention. The alarm system shall—
(a) indicate each separate alarm condition visually at the machinery alarm and control centre and provide an audible alarm at that centre and in the machinery spaces;
(b) be connected to the engineers’ public rooms and to each of the duty engineers’ cabins so that at least one of the duty engineers’ cabin is connected to the alarm system at any time. The Certifying Authority may permit equivalent alternative arrangements;
(c) be connected to an audible and visual alarm on the navigating bridge which shall be activated for any situation which requires the action of, or should be brought to the attention of, the officer of the watch;
(d) as far as practicable be designed to indicate an alarm condition should a failure of the alarm and monitoring system occur;
(e) activate an alarm that is clearly audible in the engineers’ accommodation if an alarm condition has not received attention at the machinery alarm and control centre within a reasonable time;
(f) in the event of a loss of the normal power supply, be supplied automatically from a stand-by power supply; the failure of the normal power supply shall be indicated on the alarm system; and
(g) be able to indicate multiple faults simultaneously; the acceptance of any fault on the alarm system shall not inhibit other alarms; acceptance of the alarm at the machinery alarm and control centre shall be indicated at the other positions where the alarm condition is shown; alarms shall be maintained until they are accepted and the visual indication of individual alarms shall remain until the fault has been corrected when the alarm system shall automatically be reset to its normal operating condition.

36. Safety system
A safety system shall be provided so that malfunction in the machinery which presents an immediate danger shall initiate the automatic shut down of the defective machinery and give an alarm. The main propulsion machinery shall not be automatically shut down except when continued operation would cause serious damage, complete breakdown or an explosion. Arrangements for overriding the automatic shut down of the main propulsion machinery may be permitted, provided that the operating arrangements preclude inadvertent operation. Visual indication shall be provided to show whether or not the override has been activated. A suitable notice, warning of the possible effect of overriding shall be displayed at the override position.

37. Communication
Every ship shall be provided with a means of vocal communication between the propelling engine room, main machinery control room or manoeuvring platform, as appropriate, the navigating bridge and the engineers’ accommodation.

38. Control of propulsion machinery
In every ship the speed of rotation, direction of thrust and, if applicable, the pitch of the propeller shall be fully controllable from the navigating bridge and the following provisions shall apply—
(a) the remote control from the navigating bridge shall be performed by a single control device for each independent propeller with automatic performance of all associated services including where necessary, means of preventing overload of the propulsion machinery,
(b) propulsion machinery movements selected at the navigating bridge shall be indicated at the machinery alarm and control centre,
(c) means of controlling the propulsion machinery and other machinery essential for the propulsion of the ship locally in the event of failure of any part of the automatic or remote control systems shall be provided.

39. Machinery, boilers and electrical installations
(1) An automatic control system, and an alarm system shall be provided to the satisfaction of the Certifying Authority for all important functions including pressures, temperatures and fluid levels. The control system shall be such that through the necessary automatic arrangements the services needed for the operation of the main propulsion machinery and its auxiliaries are ensured.
(2) In every ship of 1,600 tons or over, and, where practicable, in ships of less than 1,600 tons, where the electrical power is normally supplied by one generator, there shall be provided suitable load shedding arrangements to ensure the integrity of supplies to services required for propulsion, steering and to ensure the safety of the ship. There shall be adequate provision, in the event of loss of the generator in operation, for automatically starting and connecting to the main switchboard a stand-by generator of sufficient capacity to sustain propulsion, steering and to ensure the safety of the ship, and automatic restarting of the essential auxiliaries including, where necessary, sequential operation.
(3) Where stand-by machinery is necessary to ensure continuity of services essential for propulsion, automatic changeover devices shall be provided. An alarm shall be given on automatic changeover.

40. Fire safety
(1) A fuel oil and lubricating oil pressure pipe installed in a ship constructed before 1 July 1998 must where necessary be screened or otherwise suitably protected to prevent oil, in the event of a failure of that pipe, coming into contact with hot surfaces or entering machinery air intakes. High pressure fuel oil pipes of compression ignition engines shall, additionally, be provided with means of collecting at a safe location, any such oil and indicating the fault on the alarm system. (L.N. 251 of 2018)
(2) Every oil fuel tank that directly supplies the main propulsion machinery or its auxiliaries and which is arranged to be filled automatically or by remote control shall be provided with means to prevent overflow and spillage. Every such tank and settling tank fitted with oil fuel heating arrangements shall be provided with a high temperature alarm if the flash point of the oil fuel therein can be exceeded.
(3) The equipment (such as oil fuel purifiers) for preparing flammable liquids for use in boilers or machinery shall have arrangements to prevent overflow and spillages and, so far as it is reasonable and practicable, be installed in a space appropriated solely for such equipment and their heaters.
(4) All internal combustion engines having an output of 2,250 kilowatts or above or having cylinders of 300 millimetres bore or above shall be provided with crankcase oil mist detectors or engine bearing temperature detectors or other equivalent means which shall give an alarm on the alarm system in the event of an incipient dangerous condition.
(5) All air supply casings and uptakes of boilers and scavenge air belts or main propulsion engines shall be provided with detectors which shall give an alarm on the alarm system in the event of incipient fire occurring therein, unless the Certifying Authority waives the requirement for such provisions.

41. Protection against flooding
The machinery space bilge wells shall be so located that an accumulation of liquid at normal angles of heel and trim may be detected and a liquid level alarm shall be provided. The machinery space bilge wells shall have sufficient capacity to accommodate normal drainage during unattended periods. Ships with automatic bilge pumping shall be provided with a means of indicating when the bilge pump is operating more frequently than during normal operation. When automatic bilge pumping is provided smaller bilge wells may be permitted by the Certifying Authority.
