DIPTI DIAPHRAGM CLOSURE

DIPTI Diaphragm Closures are most important and cri tical installation aid for launching of Of fshore Jacket. The critical function of these Diaphragms isto withstand very high Hydrostatic pressure while launching the Of fshore Fabricated Jackets. They are specially designed to bear very high water pressureand at the same time to act as a Flexible barrier to seal ef fectively the jacket legs and enables the Platform to float in the sea, facilitating its movement andpositioning on site af ter launching. If the Diaphragm fails while launching, the whole jacket sinks in to deep sea and it would be practically very dif ficul t toretrieve the same. The specific purpose of using these flex ible Diaphragms is, it can be easily ruptured by driving piles or using integral cut ter depending oni ts design. They are also pressure tested in house, for the required pressure. Our "DIPTI" Diaphragm Closures are having 100% success rate without anyfailure and ar e supplied more than 100 Plat forms World wide. DIPTI Diaphragm Closures are available in wide range fr om 18 inch OD Pile to 144 inch OD.Pile. Special size can also be developed to suits client's requir ements.

DIPTI GROUT SEAL

DIPTI mechanical seal type Grout Seals are the superior alternative to Inflatable Grout Packers. These Grout Seals do not require any inflation system,thus reduce installation cost and of fers positive sealing. Its unique design offers an extremely reliable sealing mechanism between the Pile &Jacket Leg.Grout Packers, in the unlikely event of rupture due to human error, breakage of inflation line during launching, puncture of packer while driving the pile

through it, may fail due to non-inflation, though how rare it may be. However, our Dual Lip Grout Seal Assembly is ex tremely reliable since both the sealingrings, two lips each will cling to the pile thus making it failure proof. This seals provide a unique solution for the grouting of the jacket legs. Our "DIPTI" makeGrout Seals has proved i ts superiorit y by saving substantial cost of Grouting with 100 % success rate. DIPTI Grout Seals are available in wide range from24 inch OD to 144 inch OD Pile. Special size can also be manufactured as per client's requir ements. Grout Packers are available in wide range from 24 inchOD to 144 inch OD Pile. Special size can also be developed as per clients' requirements.

TYPICAL DRAWING OF PILE GRIPPER

DIPTI Pile Grippers are unique and marvelous engineering invention for the protection of offshore Jackets after driving pile through them, leveling ofJackets and to prevent any movement during grouting. At mid-sea waves and storm forces cause relative movements of Jacket with piles. This maydamage pile foundation severely. Hence to restrict such relative or rotational movement of Jacket, Pile Grippers fit ted on jackets are actuated hydraulically /pneumatically to hold Pile firmly and prevent any re lative movement. Pile Grippers are also used to level jackets before grouting and are ver y essential tostop slightest displacement of jacket during the setting time of grout materials. All our Pile Grippers are tested for Load test DIPTI Pile Grippers areavailable for 42 to 96 pile size. We also supply Hydraulic Power pack units with all controls for the actuation of Grippers.
