4 SAFETY EQUIPMENT SPECIFICATION

4.1 FIRE PROTECTION & DETECTION

The design and selection of all materials/equipment to be such that an efficient fire and safety philosophy in accordance with good offshore fire engineering practice is maintained. All equipment used are to be well proven in service, and are to be compliance with the Rules of SOLAS 1974 with 2004 amendments and any latest amendments thereafter and other such Regulations indicated in this specification.

Full system is to be designed, installed and commissioned by reputable supplier.

4.1.1 FIRE DETECTION SYSTEM

This system is to comprise of smoke/heat detectors and manual break-glass (or otherwise) call points wired to the main control panel located in the control room. Each of these components is to be wired back to its own group indicator in the control unit.

The system shall be capable of immediate operation at all times and no action of the crew shall be necessary to set it in operation.

The detectors shall include means for giving a visual and audible alarm signal automatically at one or more indicating units whenever any detector comes into operation. Such units shall give an indication of any fire and its location in any space served by the system and shall be centralised in the main fire control station which shall be so manned or equipped as to ensure that any alarm from the system is immediately received by a responsible member of the crew. Such alarm system shall be constructed so as to indicate if any fault occurs in the system.

The system shall be operated by an abnormal air temperature, by an abnormal concentration of smoke or by other factors that are an indication of incipient fire in any one of the spaces to be protected. The detection system shall not be used for any purpose other than fire detection.

The detectors may be arranged to operate the alarm by the opening or closing of contacts or by other appropriate methods. They shall be fitted in an appropriate position and shall be suitably protected against impact and physical damage. They shall be suitable for use in a marine atmosphere. They shall be placed in an open position clear of beams and other objects likely to obstruct the flow of hot gases or smoke to the sensitive element. Detectors operated by the closing of contracts shall be of the sealed contact type and the circuit shall be continuously monitored to indicate fault conditions. At least one detector shall be installed in each enclosed space and there shall be not less than one detector for each 37 sq m (400 sq ft) of enclosed area. In large spaces the detectors shall be arranged in a regular pattern so that no detector is more than 9 meters (30 ft) from another detector or more than 4.5 m (15 ft) from a bulkhead.

There shall be not less than two sources of power supply for the electrical equipment in the operation of the fire alarm and fire detection system, one of which shall be an emergency source.
