Where is the insulating flange typically located?

The insulating flange is typically located on shore with the loading arm. This is because its primary purpose is to provide electrical insulation between the shore facilities and the vessel, which helps to prevent electrical faults and enhances safety during cargo transfer operations. By being positioned at the loading arm, it serves as a barrier that ensures no stray electrical currents can energize the cargo system, protecting both personnel and equipment from potential hazards.

When cargo is being transferred, especially with flammable materials, preventing static electricity buildup is crucial. The insulating flange plays a vital role in mitigating risks associated with potential ignition sources. This functionality is not provided effectively if the insulating flange were to be located onboard the vessel or in the engine room, as those areas are not designed for interfacing with shore-based loading or unloading infrastructure. Similarly, placing it in the cargo hold would not offer the necessary separation from electrical systems and would not address the risks associated with the transfer process.
