Summary of Business

The Submarine Cleaner (SMC) method is a unique and unparalleled special technique developed by our company, enabling thin-layer dredging without causing turbidity. It performs dredging in areas where grab dredgers or pump dredgers cannot operate due to structural constraints or limited workspace, such as near fishing ports requiring consideration for water quality issues like pollution affecting marine aquaculture, or in front of mooring facilities.

In fishing ports where aquaculture is actively promoted, mooring facilities and other structures are often densely concentrated, creating a highly enclosed environment prone to water quality deterioration due to sediment accumulation such as floating sludge. Maintenance of facilities near aquaculture sites requires particular physical and biological consideration. The SMC method enables dredging in confined and shallow water areas. Furthermore, it allows for quiet construction without generating water pollution. Consequently, it offers advantages over other methods for dredging in fishing port areas where the construction zone is relatively small and biological considerations, such as pollution and noise, are critical.
