level indicating means 50 and the valves 52 to selectively open the valves 52 based on the desired angle that the containers 15 are to be positioned relative to the vertical referring to fig1 the method for positioning the wellhead apparatus 10 and sinking it into the ocean floor 11 comprises the initial step of connecting the suction device 30 to the lower end of the conduit 40 in a manner such that the suction device 30 is in fluid communication with the container 15 that is the suction device 30 is seated and aligned with the container 15 so that one suction port 45 is in communication with the container port 27 and the other suction port 34 is in communication with the throughhole 32 of the conduit 40 conduit 40 may be added until the wellhead apparatus 10 is on the ocean floor 11 then it is determined whether the container 15 is at the desired angle relative to the vertical this may be done in any manner well known to the art such as a camera carried by an underwater remotely operated vehicle rov or a level indicating device 50 fig4 a signal is transmitted from the level indicating means 50 to a controller means 55 to indicate the angle of the containers 15 relative.
