“DIPTI” Diaphragm Closures command a major share worldwide. They are especially designed to bear very high water pressure as a flexible barrier to seal effectively the jacket legs and enable the platform to float in the sea, facilitating its movement and positioning on site after launching.

If the diaphragm fails while launching, the whole jacket sinks in to deep sea and it would be very difficult to retrieve the same. The specific purpose of using these flexible diaphragms is, that they can be easily ruptured by driving piles or using integral cutter. They are also pressure tested in house, for the required pressure.
