Case Study
Mid Life Hull Section Rebalancing of a 1,800 DWT Cargo Vessel
A coastal shipyard performed mid-life refurbishment on a 1,800 DWT general cargo vessel. During replacement of corroded internal steel structures, a hull section became unbalanced, creating uneven draft and safety risks. Hongruntong Marine Inflatable Salvage Tubes were deployed beneath the affected hull section, enabling controlled lift and correcting the vessel's trim without inducing localized stress.
The operation was completed within a single working shift with no structural damage. Crane usage was reduced by 40%, saving time and operational costs. The salvage tubes were recovered and stored for reuse, demonstrating durability and operational reliability.
Frequently Asked Questions
1. How quickly can the tubes be deployed in an emergency?
Typically within 15-30 minutes depending on vessel size and number of tubes.
2. Can they be used on partially damaged or flooded hulls?
Yes, the cylindrical design allows flexible placement without additional stress on damaged structures.
3. Are the tubes reusable after emergency use?
Yes, after inspection and cleaning, they can be redeployed for subsequent operations.
4. What inflation equipment is required in emergency scenarios?
Standard compressed air cylinders or portable compressors are sufficient.
5. What vessel types can be supported?
Fishing vessels, workboats, small cargo ships, and other partially flooded or grounded vessels.
