Issues with working during thunderstorms
Thread Content
The Lightning Safety Code for Petroleum and Petroleum Facilities GB1559-2009 requires that “loading and unloading of petroleum products should be halted during thunderstorms, and the openings of storage vessels should be closed.” In practice, ships are usually connected to shore via hoses or transfer arms; when thunderstorms occur, operations need to be stopped. Should the connection between the ship and shore also be severed, or is it sufficient to simply stop the operations? If we only stop the operation, is it then unnecessary to remove the transfer arm and hoses?
To stop, it’s all for safety
The work has been stopped; currently, internal discussions are taking place about whether to remove the pipes and the oil transfer arms, and whether it is necessary to do so
There are also 2 types of sounds from the unit, which do not stop; this is because the relevant standards do not require such a setup, and the connection to the ship provides additional lightning protection (with lightning protection systems on both the ship and the shore)； It is said to be disconnected because there is concern that parts of the oil transfer arm may extend beyond the range of lightning protection when connected, and the ship’s lightning protection system may not be able to provide protection in such cases. I really don’t know what to do either

It’s good to stop; it’s all for safety
Given safety as a priority, the appropriate approach is certainly to disconnect
