Abstract: Diverter is an important unit of offshore drilling system equipment. FFH75×500Z diverter, with independent intellectual property rights, is developed to satisfy the demand for the self-elevating platform of 9000-meter offshore drilling package. This indicates that BOMCO has acquired the key technologies for design, manufacture and test of diverter. FFH75×500Z diverter has four specifications of high strength and tear resistant rubber cores that can meet the requirements for application under the rated working pressure of 3.45MPa. The diameter of supporting shell is 1194mm, suitable for ZP-945 rotating disc. The back export of the diverter adopts open sealing technology and depends on outer hydraulic pressure for seal clearance fit. The pressure-testing tool of the diverter can meet the demand for on-the-site installation and dismantlement of rubber cores and pressure test of diverter at the same time, simplifying the operational procedure on the field. This diverter is put into production and has been sold for six units. It passes the CCS appraisal and can be used for Dubai self-elevating platform.
