What is a Fallpipe Vessel?
A fallpipe vessel is a specialized vessel designed for the precise placement of rock fill on the seabed. Its main application is the stabilization of underwater pipelines, cables, as well as the creation of artificial reefs and protective structures on the shelf
How does a fallpipe vessel work?
The key feature of a fallpipe vessel is a vertical guide pipe (fallpipe), through which rock material is fed from the side of the vessel directly to the bottom. Thanks to the positioning system (usually DP system) and controlled release of materials, high installation accuracy is ensured even at depths of more than 1,000 meters
Applications:
• Installation of a protective layer over underwater pipelines and cables
• Construction of offshore structures and platforms
• Strengthening the seabed in areas with high current dynamics
• Creation of artificial reefs
Advantages of using a fallpipe vessel:
• Installation accuracy: minimal deviations from the design line
• Deepwater work: possibility of operation at great depths
• Cost reduction: reduction in the volume of processing and rework
• Environmental safety: minimal impact on the environment
Conclusion
Fallpipe vessels play a key role in modern offshore projects - from energy to infrastructure. Their use ensures the efficiency, accuracy and reliability of underwater construction operations.
