I need the operating procedures or manual for an LNG loading crane pipe!

Operating procedures for LNG filling – Precautions: Filling operations can only be carried out after receiving a notification from the Sales Department and an assignment order being issued； After the task order is issued, it is necessary to verify whether its contents are accurate and complete ； Before connecting the hose, fill out the inspection forms before and after filling the tank truck; the information provided must be accurate and reliable ； During the filling process, the tank truck engaged in illegal operations; despite warnings from the on-duty staff, it failed to comply and was stopped from continuing with the filling process, after which it was handed over to the Consumer Protection Department for handling ； Operation procedure: Manually turn the loading pump, open the seal gas manual valve to check whether the seal gas is functioning properly; once it is working correctly, proceed with the following steps ； Close the outlet manual valve of the loading pump, and at the same time open the tank return valve as well as the liquid-phase line return valve ； After opening the manual valve (root valve) for liquid discharge from the storage tank, simultaneously open the bypass of the SDV-902 programmable valve; this should be done slowly to avoid damage to the pipelines due to low temperatures. Once an airflow sound is heard, slowly open the manual valve for liquid inlet of the loading pump, and the BOG manual valve – gas flow is indicated by the presence of such a sound ； The temperature of the cold pump is required to drop by one degree Celsius per minute, with the cooling process lasting no less than 120 minutes ； During the operation of the cold pump, it is necessary to closely monitor its condition to detect any signs of leakage. If leakage is detected, the cold pump should be stopped immediately, and the maintenance team should be notified to carry out repairs. Operations can resume only after the repairs are completed and the requirements are met ； When the vehicle is weighed, an operator must be present to supervise the weighing process. During the cooling phase, it is necessary to check whether the pressure inside the tank of the tank truck is below 0.3 Mpa; if the pressure is too high, loading is denied. It is also important to verify that the safety accessories are in good condition and that all relevant documents are valid. All inspection results must be recorded in detail, with the driver’s signature confirming them before the filling pipelines can be connected to the tank truck. Once connection is complete and everything has been checked, the driver of the tank truck is informed
