IRM Diaphragm Closures are the most critical installation aid for launching the Offshore Jacket.
The critical function of these Diaphragms is to withstand very high hydrostatic pressure while launching the offshore jackets. They are specially designed to bear very high-water pressure and, at the same time, act as a flexible barrier to seal the jacket legs effectively, and it enables 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 into the deep sea, and retrieving the same would be difficult. The specific purpose of using these flexible diaphragms is that they can be easily ruptured by driving piles or using an integral cutter, depending on its design. They are also pressure tested in-house for the required pressure. Our IRM Diaphragm Closures have a 100% success rate without any failure and are used in more than 100 platforms worldwide.
IRM Diaphragm Closures are available in a wide range from 20-inch OD Pile to 200-inch OD Pile. Special sizes can also be developed to suit the client's requirements.
Product Highlights
- Flanges are shaped to avoid stress concentrations within the diaphragm.
- Made from highly reinforced rubber, designed to withstand the hydrostatic pressure during jacket flooding operations.
- Tested up to 1.5 times the operating pressure.
- ASTM A36 or equivalent material used for the retaining rings/flanges.
