The packer has been attached to the screen and lowered through the rig floor to the moonpool. The moonpool area is just below the rig floor. The vertical shiny metal pipe in the middle left of the picture is the bottom of the casing packer. The moonpool is a large hole in the middle of the ship through which the drill pipe is lowered as well as other hardware used for drilling. The tilted cone-like metal structure in the middle right portion of the picture is a reentry cone that has been prepared to be deployed through the moonpool at the next site to be drilled.
