Abstract: An offshore sewage treatment facility or sludge facility is serviced on a ship. The ship is secured and in position by means of a single point mooring system which is attached to the vessel's stem or stern and is connected to a submerged pipeline as a conduit from the shore. This offshore facility is alternatively housed aboard a conventional offshore platform. The facility is totally and/or partially energy self sufficient by means of utilizing methane gas generated by the processing plant. The processing facility allows for primary and secondary waste water treatment and digestion, dehydration of sludge or solids, generation of methane gas, drying of sludge or solids and pelletization of sludge with end products or by-products of recyclable water for industrial and/or agricultural purposes, fertilizer after the dry sludge is mixed with potash, or the dry sludge may be manufactured into blocks suitable for the construction of buildings.
