DEVICE FOR PURGING INTERNAL VOLUME OF SUNKEN SHIP Russian patent published in 2023 - IPC B63C7/10 

FIELD: marine engineering.

SUBSTANCE: invention relates to technical devices used in raising sunken objects by restoring their buoyancy through displacing water with compressed air from their internal volumes. The device for purging the internal volume of a sunken ship is made in the form of a U-shaped pipe welded to the bottom of the cover with an opening and is designed to be hermetically installed on a cut-out in the upper part of the structure of the purged internal volume, the free end of which is designed to be discharged into the upper part of the purged internal volume and with the possibility of placing along the length of the blown internal volume closer to the tip of the sunken object, which is raised first. EFFECT: ensuring the release of expanding air from the purged internal volumes when the external hydrostatic pressure drops.
