With Marine Rubber Balloons , On 26th May , a 97 m long , 18.2 width  cutter suction dredger was safely launched and successfully entered into the water .

Considering length and width of the dredger with its dredging depth of 26 meters ,discharging distance reaches 6000 meters , we  planned 27 piece of marine balloons for this project . But when we are on the site , we found out the weight distribution of the dredger itself is quite different ,we need to adjust the placement of the airbags accordingly . Also, the bottom structure of the dredger is somewhat obstacle  for ship balloons moving and rolling ,hence , some additional structures should be deployed for this launching project .

Our engineers made detailed calculation and insert enough airbags in some areas due to unexpected low water level to make full preparations . When the water level reaches its highest point , people release the dredger, dredger goes into water quickly under the help of airbags .
