Burty pianowe w ochronie zbiornika z pokrywą pływającą

"In case of fire weather shields or parts of the seal shall not affect the flow of the foam into the seal area.

NOTE This can be achieved by a circular gap of 100 mm height between weather shield and pontoon, or burn out openings with closures, or the choice of the material of the secondary seal, which will be destroyed at 300 °C in such a way to allow a regular foaming of the circular gap."
