The Reliever


Relieves onshore treatment facilities during upgrades, routine maintenance, or repairs.


The Reliever retrieves and treats wastewater from shore-based facilities and discharges treated water back into local bodies of water. This ship design features primary and secondary water treatment components. During the treatment process, organic waste from sewage can be obtained, treated and used for other purposes, including agriculture and energy consumption.

Who It Is For:

An area where a land-based wastewater treatment plant needs upgrading, is malfunctioning, or has insufficient capacity.


Reduces negative impact on marine environment by avoiding discharge of polluted wastewater. This is especially helpful when insufficient wastewater treatment solutions are available onshore.


Need or requirement for wastewater treatment must be present.


Countries and areas with insufficient wastewater treatment facilities.

Key Benefits:

  • Mobility: Can serve a community for a short or long period of time; ship can be redeployed when its mission is complete.
  • Construction Flexibility: Ship can be deployed and operable at a location in a short period of time.
  • Relatively Low Cost: Compared to an onshore plant, a lower investment is required to mobilize a “floating” offshore plant. Again, the ship can be utilized for shorter or longer periods of time, resulting in cost savings and/or cost flexibility.
