  • Patent number: 8661877
    Abstract: Apparatus and method for testing float equipment used in the construction of wellbores for the hydrocarbon exploration and production industry. The apparatus has a housing and an opening for receiving an item of float equipment. A seal arrangement is configured to seal with the item of float equipment, such that the housing and seal arrangement together define a test chamber. The test chamber is pressurized to expose at least a part of the item of float equipment in the test chamber to a test pressure. In embodiments of the invention, at least a part of an outside surface and at least a part of the item of float equipment may be simultaneously loaded. The tests performed more closely simulate the conditions to which the equipment is exposed in a wellbore.
