PAO OMSKNEFTEKHIMPROEKT (ONHP) is prepared to construct spherical tanks (spheres) of various capacities on “turnkey” basis. Currently, the company is developing engineering design of 10,000 cubic meter sphere. Earlier, ONHP specialists had already developed engineering designs of 600 cubic meter spheres and 1,000 cubic meter spheres, as well as 2,000 cubic meter spheres and 5,000 cubic meter spheres for pressurized storage (0.245-1.746 MPa) of highly-flammable liquids, liquefied and compressed gases.
