Vessel Separation Device (VSD)
Area of use
- Three wire system with three pendants of different length.
- The first wire (shortest) is a trip wire that can initiate an audible and/or visual alarm to warn of vessel movement.
- At a pre determined distance the second wire (middle length) is activated and initiates the ESD 1 signal. This signal is taken into on board ESD system shutting pumps and closing ESD valves.
- At a pre determined distance, the third wire (longest) will activate, initiating the ESD 2 signal which is sent into the HPN2 PERC release unit, via the on board ESD system, activating the PERC.
