Port of Portland, Terminal Dredging

Overview

HME was contracted by the Port of Portland to perform maintenance dredging at Terminal 4, ensuring continued safe vessel access for cargo operations. Over 48,000 cubic yards of sediment were removed to restore the necessary channel depth, supporting efficient port logistics.

The project required clamshell dredging with sediment placement at an approved in-water disposal site, all while maintaining compliance with state and federal environmental regulations.

1. The Challenge

• Restore channel depth to accommodate commercial cargo vessels.
• Execute dredging while minimizing disruptions to port operations.
• Ensure compliance with state and federal environmental regulations.

2. The Solution

• Clamshell dredging was utilized for efficient sediment removal.
• Sediment was transported to a designated in-water disposal site approved by regulatory agencies.
• Work was completed on time and in full compliance with permitting and water quality standards.

3. The Impact

• Restored navigability for commercial cargo vessels at Terminal 4.
• Removed 48,000 cubic yards of sediment, maintaining safe depth requirements.
• Ensured compliance with all regulatory and environmental guidelines.
• Maintained port operations without disruption to cargo handling.

Conclusion

HME’s dredging operations at Terminal 4 in Portland, OR, successfully improved port accessibility while maintaining regulatory compliance and operational efficiency. This project reinforces HME’s expertise in precision dredging and sediment management for high-traffic port facilities.
