For loading light oil nowadays, are lower-mounted dip pipes or upper-mounted dip pipes generally used, and is oil and gas recovery equipment available in either case?
Now it’s all loading underwater; some of it is
In accordance with the new requirements for WOCs management, it is essentially necessary to install lower-level equipment along with oil and gas recovery systems
Use a overhead hose, as mentioned upstairs – it’s for loading from below the liquid level, and there is oil and gas recovery equipment available

Your question cannot be answered in just a few words; first, are you familiar with upper and lower hose assemblies, and second, where is the project located? The following points are provided for your reference: 1. The lower loading hose is connected using a quick connector (dry break valve), and it needs to be compatible with the tank truck – whether the truck used for loading is one with an upper loading system, a lower loading system, or both. 2. According to existing regulations, loading must also be done underwater, with a sealed air return system in place. Currently, the sealing measures used for the loading nozzles are mostly merely nominal and provide little actual sealing effect. Our company possesses a new technology for sealed loading at the top of the tank (**inventive patent**). 3. Whether to use a loading arm at the top or at the bottom of the tank should be determined based on the specific conditions of the project site; if there are sufficient tank trucks available for bottom-loading, then bottom-loading should be used, while if no such trucks are available, top-loading is the only option. If both types of tank trucks are available, then both types of loading arms should be used.
The current requirement for tank trucks is an upper mounting unit for gasoline recovery
GB50074-2014 has relevant provisions
