The concept of ocean disposal site is proven technology. One of the most concerns in ocean disposal site is the leakage of pollutants into the ocean from waste materials. In order to prevent its happening, technically, a vertical impermeable wall is constructed around the disposal site. However, the conventional method fails to guarantee zero leakage due to method’s limitation. This paper presents the use of CCC (chain conveyor cutter) method to construct vertical impermeable wall. The feasibility of CCC for ocean disposal site is evaluated by means of pollutant dispersion model, and moreover, the result is compared with conventional method. The result indicates that the CCC method is technically feasible for ocean disposal site’s construction. Additionally, this method shows better as for technique and economic point of view than that of the conventional method. One of advantage of CCC method is the ability to construct homogeneous wall in regard to strength and permeability, which cannot be found in the conventional ocean disposal technology.
