The 7.5m Ship Launching Balloon is a high-precision, heavy-duty solution designed for medium-to-large vessel launches under complex maritime conditions. Manufactured from multi-layer reinforced rubber with embedded high-tensile synthetic fibers, the balloon combines superior strength, elasticity, and durability. It provides uniform pressure distribution beneath the hull, minimizing stress points and preventing structural deformation during launches.
In 2020, a Malaysian shipyard required the launch of a 1,800-ton bulk carrier in a facility with uneven dock surfaces and restricted crane access. Using the 7.5m Ship Launching Balloon system from Hongruntong Marine, the balloons were strategically positioned and inflated in stages to maintain consistent pressure distribution. The launch was completed successfully within 50 minutes with zero hull damage or structural stress, resulting in significant operational time and labor cost savings.
