1．流程步骤

序号	负责人员/部门	步骤描述	备注
010	槽车司机	槽车到达LNG站	司机入厂登记领取出入证填写：临时出入登记表
020	槽车司机	槽车重车过磅	司机按要求过磅
030	LNG站操作员	实施停车安全措施	1.槽车停稳后﹐驾驶员熄灭发动机及关停手机并启动车轮抱死装置罐车。 2.槽车熄灭发动机后﹐操作员收取槽车车匙存放指定位置。 3. 槽车轮胎下放置防滑垫胶。 4. 槽车是否已接地。 5．填写气源厂装卸 LNG检查表。
040	LNG站操作员	检查槽车安全附件及危运证件	1.检查槽车罐体、压力表、安全阀在检验有效期内。 2.槽车驾驶员随车携带有效的“四证一报告”。
050	LNG站操作员	填写司机及危运证相关资料	1．填写司机及危运证相关资料及LNG装卸记录表
060	LNG站操作员	消防设施及环境因素检查	检查装卸台边灭火器材合格有效、周围是否有潜在引火源及不安全因素。
070	LNG站操作员	卸车管道吹扫及预冷	卸车软管完好连接并吹扫：卸车相关管线开启及预冷。
080	LNG站操作员	选择卸车储罐	确保LNG储罐有足够的充装空间。
090	槽车司机	LNG槽车储罐增压
100	槽车司机	检查压力是否已到位	保持槽车储罐与LNG站储罐压差于0.2MPa
		结果是：走至100 否：重回090
110	槽车司机及LNG站操作员	开启相关阀门开始卸车并填写装卸检查记录	开启相关阀门开始卸油
120	LNG站操作员	储罐上进液管进液	开始15分钟上进液；槽车压力是否稳定在0.4～0.7MPa，并高于进液储罐压力，但要低于槽车最低安全阀排放压力0.1MPa以上。
130	LNG站操作员	转换为下进液管进液	15分钟后
140	LNG站操作员	槽车余压BOG回收	观察槽车液位计，确认槽车无液体。检查槽车压力，若超压时；通过BOG气化器回收，使槽车压力处于0.2MPa。
150	LNG站操作员	BOG回收完成后后续工作	1.关闭槽车及储罐的相应阀门以及进液管与其中一个罐保持连通。 2．放散金属软管内余气，无压力时卸下金属软管。 3．拆下静电连接线，确认车辆所有接驳点已分离后取出车轮固定楔。 4. 完成上述内容后,将槽车钥匙交驾驶员。
160	槽车司机	槽车空车过磅	1.司机按要求过磅 2.记录磅单相关数据
		卸车结束	卸车结束填写装卸检查记录并签名

2．流程所需的报表与表单

序号	表单名称	表单编号
1	LNG站临时出入登记表	JYNY-032-01
2	气源厂装卸 LNG 检查表	JYNY-032-02
3	LNG装卸记录表	JYNY-032-03
