Tankers operating with a cargo tank cleaning procedure using ____ shall be fitted with an ____ system complying with the Fire Safety Systems Code and with fixed tank washing machines. However, inert gas systems fitted on tankers constructed on or after 1 July 2002 but before 1 January 2016 shall comply with the Fire Safety Systems Code, as adopted by resolution MSC.98(73).

请简述惰性气体系统的检查实践包含哪些内容？

2. INSPECTION PRACTICE 2.1 CERTIFICATES/DOCUMENTS/ RECORDINGS Calibration cert of Oxygen analysis meter /portable gas detector Recordings of Oxygen content in IG (Refer to SMS) Maintenance recordings... (Refer to SMS) 2.2 EQUIPMENTS Wheel house, C.C.R, Main Deck, Engine Room... 2.3 OPERATION/TESTING Alarm Testing, Demonstration, Oxygen content in Cargo tanks measuring... Clear Grounds: (1) Evidence of leaks in the inert gas piping on deck; (2) Faulty portable gas detectors, lack of spare parts, or inability to provide test certificates; (3) Malfunctioning indicator lights on the inert gas system control panel; (4) Oxygen analyzer panel records showing oxygen conten repeatedly exceeding 5% for prolonged periods. CCR(Cargo Control Room): (1) Check whether any abnormal alarms are on IG indicating penal or not ; (2) Confirm Oxygen content not more than 5% by volume and gas pressure not less than 100 mm water gauge on Oxygen analysis meter, and review the recording history. (3) Check the temperature of the inert gas at the discharge side of the system, whenever it is operating. (4) Test all indicators condition on IG indicating penal, confirm relevant valves condition are correctly indicated. (5) Test audible and visual alarms which are provided, based on the system designed, for the system indicating: ① oxygen content in excess of 5% by volume; ② failure of the power supply to the indicating devices; ③ gas pressure less than 100 mm water gauge. The alarm arrangement shall be such as to ensure that the pressure in slop tanks in combination carriers can be monitored at all times; ④ High-gas pressure;【缺少答案，请补充】（含图）（含图）（含图）（含图）（含图）

Test audible and visual alarms which are provided, based on the system designed, for indicating: ① oxygen content in excess of 5% by volume; ② failure of the power supply to the indicating devices; ③ gas pressure less than 100 mm water gauge. The alarm arrangement shall be such as to ensure that the pressure in slop tanks in combination carriers can be monitored at all times; ④ High-gas pressure; ⑤ Failure of the power supply to the automatic control system; ⑥ Low water pressure or low water flow rate to the scrubber; ⑦ High water level in the scrubber; ⑧ Failure of the inert gas blowers; ⑨ High gas temperature;（含图）（含图）

SOLAS 1974 Amend 1981 (effective date: 01-Sep'-1984) Inert gas blowers and gas regulating valve automatic shut down: * Low water pressure or low water flow rate to the scrubber; * High water level in the scrubber; * High gas temperature at the discharge side of the inert gas blowers And Inert gas blowers shut down will result in the gas regulating valve automatic shut-down.

Confirm the positive indication of the operational status of the stop valves on IG branch piping leading to each cargo tank are provided. (Apply to vessels constructed on or after July 01,2002 and before January 01,2016) Confirm the control system shall provide unambiguous information of the operational status of such valves to the control panel of IG system. (Apply to vessels constructed on or after January 01,2016) （含图）

Confirm the audible and visual alarm on the low level of water in the deck seal shall operate at all times, and on-site test this alarm function.

Confirm an audible alarm system independent of that required in above 3.1.5.3 or automatic shutdown of cargo pumps be provided to operate on predetermined limits of low pressure in the inert gas main being reached. ( gas pressure less than 100 mm water gauge.)

Confirm the inert gas can be automatically vented to atmosphere. if the oxygen content in manifold exceeds 5% by volume, (Apply to vessels constructed on or after January 01,2016)

Confirm the audible and visual alarm on the low level of water in the deck seal shall operate at all times， and on-site test this alarm function.

Confirm an audible alarm system independent of that required in above 3.1.5.3 or automatic shutdown of cargo pumps be provided to operate on predetermined limits of low pressure in the inert gas main being reached.

Confirm the inert gas can be automatically vented to atmosphere. if the oxygen content in manifold exceeds 5% by volume,

Confirm the water level in deck seal is normal, and 【缺少答案，请补充】（含图）

any means for protecting this deck water seal against freezing is provided, for example , steam pipes for heating; (缺图)【缺少答案，请补充】

Confirm a water loop or other approved arrangement are fitted to each associated water supply and drain pipe and each venting or pressure-sensing pipe leading to gas-safe spaces, and means for preventing such loops from being emptied by vacuum are provided; (缺图)【缺少答案，请补充】

Check the relevant IG pipes and joints on deck have obviously rust and leakage or not; 【缺少答案，请补充】（含图）

Check the stop valves on IG branch piping leading to the cargo tank are controlled by locking arrangements, for example, locker, hex key, special tool etc. These arrangements shall be under the control of a responsible ship’s officer; (缺图)【缺少答案，请补充】

Check and confirm the oxygen content in every cargo tank not more than 8%; 【缺少答案，请补充】（含图）

Manually test the function of PV valves for cargo tanks; (缺图)【缺少答案，请补充】

Check and confirm the oxygen content in every cargo tank not more than ______; (缺图)
