Abstract: A production apparatus (120) configured to be connected to an emergency disconnect package (EDP) (135), comprises a housing (190) defining a wellbore (161); a first wellbore valve member (361) for closing the wellbore, the first wellbore valve member provided within the housing, the first wellbore valve member being capable, in use, of shearing an object located in the wellbore; and a second wellbore valve member (162) for closing the wellbore, the second wellbore valve member provided within the housing, the second wellbore valve member being capable, in use, of shearing an object located in the wellbore. The provision of a production apparatus with wellbore valve members and being directly connectable to the EDP, obviates the need for a lower riser package (LRP) which would normally provide the required emergency shearing/cutting and sealing functionalities.
