When discharge the tanker, the system automatically monitors the limit of the tank on the shore and the complete unloading process by connecting it to the process control system on the shore. During the unloading process, it is possible to interrupt or stop the process from 2 independent points using the EX-Remote system (dead man / emergency stop). On the shore, the system is permanently connected to the haven process control system and controls the complete unloading via radio. Overfill is not possible. This system works without a cable connection between land and ship and thus significantly increases the occupational safety of the user. To guarantee the long discharge times (up to 36 hours of continuous operation), the LRC ADN battery case is used.
When loading or unloading of hazardous fluids from

For this purpose, a separate, on-board, intrinsically safe current loop on the shore must be interrupted by an electrical contact.
