The RO units are to be installed aboard two diving support barges currently under construction in the Holland Shipyards site in Hardinxveld-Giessendam, the Netherlands. The diving barges are scheduled to be deployed along the Gabon coast.
Each unit will provide drinking water at a rate of up to 6 m3 per day. Upon completion, the barges will operate along the Gabon coast. The two Tethys units are scheduled for deployment in August and September.
