API Plan 65

Leakage Detection Vessel (LDV) 

In API Plan 65 arrangements, leakage from the seal faces is collected via a drain port and directed to a liquid-collections system via a vessel equipped with a high-level alarm.

An AESSEAL LDV can be installed to collect the leakage and can be fitted with a level switch to sound the necessary alarm as the vessel begins to fill (switches can be supplied for different zoned environments)  


  • Robust vessel to withstand arduous environments       
  • Integral weld pad level gauge to show leakage level in the vessel      
  • Level switches can be supplied for different zoned environments
