ABSTRACT:
A method and apparatus for testing a blowout preventer packer element of a diverter system on an offshore drilling rig utilizes an inflatable packer. The packer has a tubular member than extends upward through the diverter packer element. The packer has an expansive seal element that seals in the upper portion of a marine riser assembly. The diverter packer element is closed around the tubular member, while the packer seal element seals against the upper portion of the marine riser assembly. Fluid pressure is applied to the diverter system port to test for leakage.
