GB 18434 Safety requirements for oil tankers operating in port
3 Terms and Definitions
The following terms and definitions defined in GB 18434 apply to this document.
3.1
Standing time setting time
When production is carried out in a place with static electricity hazards, the static electricity carried by the material (usually liquid) dissipates to a safe value after the equipment stops operating.
Next, allow the interval time required for the next step.
3.2
relaxation time relaxation time
The time required for the charge (or potential) on a charged body to dissipate to 1/e (about 37%) of its initial value.
4 General requirements
4.1 Ground protection
4.1.1 Equipment grounding protection
4.1.1.1 The total leakage resistance between the oil tanker components and the earth is not to be greater than 1MΩ, and the grounding resistance is not to be greater than 100Ω.
4.1.1.2 The connecting wire should be an easy conductor such as annealed copper stranded wire, copper sheet, white steel sheet or white steel plum blossom gasket, and its cross-sectional area should not be less than 5.5mm2.
4.1.1.3 Insulating flanges and insulating hoses should be inspected regularly to confirm that their insulation resistance is not less than 1000Ω, and the inspection period should not exceed 1 year.
4.1.2 Operational ground protection
4.1.2.1 Insulating flanges or insulating hoses shall be used between the oil pipeline on the wharf and the oil pipeline on the tanker, and the oil pipeline on both sides shall be
Grounding alone, the hull should not be grounded by means of jumper wires.
4.1.2.2 All metal components in explosion-hazardous areas, including the external protective layer, shall be reliably grounded.
4.1.2.3 During the ship-to-ship transfer operation, insulating flanges or insulating hoses shall be used to connect the two ships, and spans shall not be used between the oil pipelines on both sides.
