ISR Shearing Blind RamInterlocking Shear Ram (ISR) is available for the U type BOP line. The ISR rams provide an improvedshearing capacity alternative to the standard SBR rams, and should only be used when the standardrams cannot handle the desired shearing load. Since the geometry of the ISR ram incorporates a “V”shape and is designed as wide as possible, it can shear multiple strings and drill pipe as large as 6-5/8”OD. Also, ISR rams do not have to fold over the lower fish. This means less force is required to shearand, by leaving the fish open, kill mud can be pumped down the severed drill string. The interlockingmechanism incorporated in the ISR means that these rams can be utilized in an oversized cavity withoutfear of a leak at low wellbore pressures.1012574923116SD 034603U and UM BOP ISR Shearing Blind RamBOP Bore Sizeand WorkingPressure (psi)13-5/8”3000, 5000 and10,000BOP Bore Sizeand WorkingPressure (psi)13-5/8”3000, 5000 and10,0002-7Upper RamSubassembly2Body3SidePackerDescription and Item Number4SidePacker5TopSeal6BladeSeal7BladeSeal2164775-01 2164773-01 2010985-01 2010985-02 6445033-01-00-01 2010986-01 2010986-029-14Lower RamSubassembly9Body10SidePacker11SidePacker12TopSeal13*BladeSeal14*BladeSeal2164776-01 2164774-01 20101985-01 2010985-02 6445033-01-00-01 2010986-01 2010986-02* Not ShownTC1001 51 © 2002 Cooper Cameron, Cameron Division
