Marine Works & Dredging Services

At Sea Floor Solution, our marine works and dredging services represent the cornerstone of our operations in Thanjavur and across Tamil Nadu. With specialized cutter suction dredgers, clamshell dredgers, and trailer suction dredgers, we tackle the most challenging underwater sediment removal projects with precision and efficiency.

Our Dredging Capabilities Include:

1. Channel Deepening & Maintenance

Port authorities, fishing harbors, and inland waterways require consistent depth maintenance. We use high-capacity cutter suction dredgers capable of handling sand, clay, and soft rock formations prevalent in Tamil Nadu's rivers and coastal areas. Our GPS-guided dredging ensures precise depth control within ±5cm accuracy, meeting international navigation standards.

2. Silt Removal from Lakes & Reservoirs

Thanjavur's irrigation tanks and reservoirs face chronic siltation issues. Our clamshell dredgers with 2-5 cubic meter grab capacities efficiently remove accumulated silt while minimizing water turbidity. We deploy sediment containment booms and silt curtains to protect downstream water quality during operations.

3. Beach Nourishment & Coastal Protection

Coastal erosion threatens Tamil Nadu's beaches and fishing communities. Using trailer suction hopper dredgers, we pump suitable beach-quality sand from offshore borrow areas to replenish eroded shorelines. Our projects follow Central Water Commission's coastal protection guidelines, ensuring long-term beach stability.

4. Land Reclamation Projects

For port expansions and industrial development, we create new land through hydraulic fill dredging. Our 12-inch discharge dredgers can pump 2000 cubic meters per hour, enabling rapid land creation while maintaining environmental compliance through turbidity monitoring and marine life protection measures.

Technical Specifications of Our Dredging Fleet:

• Cutter Suction Dredger: 18m length, 500HP main pump, 1000m3/hr capacity

• Clamshell Dredger: 3m³ grab, 30m working depth, crane-mounted

• Trailer Suction Hopper: 500m³ hopper capacity, dynamic positioning

Environmental Compliance & Sustainability

All dredging operations comply with Tamil Nadu Pollution Control Board (TNPCB) norms. We use real-time turbidity meters, conduct pre- and post-dredge bathymetric surveys, and implement fish-friendly dredging schedules. Our sediment disposal follows MoEF&CC guidelines with designated disposal sites approved by port authorities.
