Flotation tanks Pronal also specializes in the design and manufacture of flexible structures aimed at ensuring floatability, these flotation tanks are used to facilitate lifting and positioning of underwater loads such as raising shipwrecks, and assisting divers to move equipment on the seabed...

The range comprises a wide choice of models:
- Underwater parachutes and lifting units are standard products designed for use in multiple marine and offshore applications. When filled with air they can be used to handle loads up to 5 tonnes.
- Deep sea flotation tanks can raise loads situated at a depth of up to 4,000 metres. In order to float they are filled with a liquid with lower density than that of seawater. This type of equipment was used to raise wreckage from the Titanic.
- for special applications, specific systems are designed and modified by our engineering department to deal with situations where operations are hampered by particular constraints. 

Advantages : - easy and speed installation, - compact when folded, - lightweight, - safe to use.
