How to avoid ship launching risks – Marine launching airbags
Since the first use of ship airbags in the Xiao Qinghe River shipyard in1918, the marine airbag has been applied worldwide with its superior performance, high-cost efficiency, and low maintenance costs. However, some accidents have occurred due to improper delivery of airbags, poor launch conditions, and the following potential risks.
1. Water level
Although airbags can overcome water shortage to a certain extent, they still have water level restrictions. If the vessel is launched in the case of insufficient water level, the following phenomenon may occur: the stern is suddenly declining – may result in rust and launch of the marine airbag. Sometimes it may also cause the bow to lift, resulting in a collision between the bow and the ground.
In order to avoid the above phenomenon, you can try the following methods to solve the problem:
1) Extend the slide of the underwater part.
2) Increase the buoyancy of the ship by increasing a buoyancy tank or airbag in the cabin.
2. Launch ramp
Regardless of the landing method, a ship landing accident occurs every year. Although it is the safest method of water with airbags, there is still a fault due to improper operation. In that case, people always blame the quality of the airbag on airbags, but they ignore the importance of starting ramps.
The launch ramp should also be ready, may not be a concrete ramp, but a clean compact ramp. On the left, the ramp is full of stones and garbage, which makes the ramp are too strong and cannot scroll. The downhill may also damage the hull of airbags and vessels.
3. Holding system
The ship maintains the system of ignorance, such as ground anchors, pulleys, wire ropes, winches, and binding that may lead to water underwater. For example, the bulldozer used to fix the ship is undoubtedly inseparable because they cannot provide sufficient fixed strength.
In order to avoid the above accident, we should carry out careful arrangements and precise calculations. Check the maintenance system before starting.
