Safe operation

Safe operation

Chemicals, acids, oils and edibles must be handled in a way that is safe, not only for people but also for the environment. Framo cargo pumping systems efficiently empty cargo tanks and piping, and they can withstand the tough impact of tank cleaning that follows. That ensures peace of mind in switching between cargoes, with no risk of cargo contamination, so your vessel can carry anything from acids to drinking water.

Stripping

When the cargo tank is empty, the speed of the cargo pump is reduced to perform the final stripping of tank.

Stripping (left image)

  • Close the cargo valve.
  • Open the small ball valve on the stripping line.
  • Pressurize the pipe stack by connecting the purging hose with compressed air or nitrogen.
  • Press cargo out through the stripping line and into the cargo line.The pump impeller rotates and acts as a non-return valve to prevent cargo from returning back to tank.


Purging and seal monitoring (center image)

  • From deck level
  • The pump’s cofferdam is purged before and after discharge operation. Any leakage across the cargo seals or hydraulic oil seals collected in  the cofferdam, will be forced to the exhaust trap on deck where it can  be measured. This is a simple and reliable seal condition monitoring system. No need for any electric sensors nor  any automatic control system.


Vacuum drain (right image)

  • The standard Framo cargo pump design meets all applicable rules for stripping under the IMO Annex II requirements. However, as an option, the Framo cargo pump can be equipped  with a vacuum drain line that will  empty suction well completely and allow for a dry tank top and quick re-loading of cargo.
