<p>Treated sewage is loaded into the tanks (2) of a large ocean going tanker (1) and transported to a deep water site, e.g. 7000m It is then deposited directly onto the seabed at that site through piping (6) deployed from the vessel and extending downwardly. The piping may be a flexible hose, e.g. plastcis tubing in con continuous or segmented form, or as string of steel pipes, or a combination of the two. The piping may be deployed over the side of the vessel, or pref. from a moon pool (9). In extremely deep water it may not be necessary for the piping to extend fully to the seabed. The tanker is provided with a hose reel and/or pipe erection plant and/or equipment for handling piping and for deploying the disposal piping from the tanker to the deep seabed disposal region.</p> |
