Ship launching marine airbags was used to\u00a0launch the 58,000 DWT cargo ship successfully in Zhejiang China on Feb.2010. This ship launching project set the new world record of ship launching by marine\u00a0air bags in the marine engineering industry.<\/span><\/p>\n

\"Evergreen<\/p>\n

This cargo ship holds 11,800 tons is 199 meters long and 32 meter wide. It is built on a 0.87 degree concrete ramp whose end is a sluice gate. From the water gate to ship\u2019s stern is 15 meters. And the water beyond the gate is 8 meters deep.\u00a0Total 76 pieces YT-6 type ship launching airbags were employed to complete this project and two 25 tons winches.<\/span><\/span><\/span><\/p>\n

For big ship launching and\u00a0vessel’ haul out\u00a0project, the scientific design from calculation is vital for success. To ensure this DWT58, 000 cargo ship\u2019s safe launching, there are two conditions must be satisfied. Avoiding the \u201cbow decline\u201d during the launch process. Second is the rush distance is controllable when ship is after launch.\u00a0<\/span><\/span><\/span><\/p>\n

It’s the largest barges ever launched by Evergreen Marine airbags. Evergreen<\/span>\u00a0engineers gathered together taking 24 hours thingking and consideration to calculate the launching project. From mathematic modeling to computer simulation, every step of launching process were researched carefully. From the water level to weather variety, most conditions were considered for the design.<\/span><\/span><\/span><\/span><\/p>\n

When finally the arrangement of airbags was decided,\u00a0Our engineering company\u00a0find the stern rope must be added to control the rush after launching. So 4 extra stern ropes were demanded to fix on the bollard with 45 degree angle to the ship. And the time of cast anchor is also stated.<\/span><\/p>\n

\"Evergreen<\/p>\n

At 31 Jan, Eversafe\u00a0<\/span>completed the\u00a0raise of\u00a0ship\u00a0and\u00a0remove of\u00a0block. At that time, two winches pulled ship from slips but blocks remain stern under the vessel. Estimated that the highest tide of 1 Feb. will at 10:30 AM. \u00a0So launching time\u00a0planned\u00a0at\u00a010 AM.<\/span><\/span><\/span><\/p>\n

At 9:30 AM,\u00a0we began to adjust the inner pressure of ship launching airbags at stern to be 0.12Mpa. Then released\u00a0wire ropes from winches.\u00a0At 9:50 AM, the ship launching marine airbags under gravity center and bow were inflated to be 0.15Mpa. Ship began to move slowly by riding rolling airbags.<\/span><\/span><\/span><\/p>\n

During the launching, the ship\u2019s incline angle is increasing until the stern floated when the bow entered into deep water already. There is no \u201cbow decline\u201d phenomena occurred seems as what we have calculated.\u00a0\u00a0Then ship advanced in the sea for a certain distance its bow anchors was casted. Four stern ropes were trained. So ship moved sideways then it was pushed by two tug boats to mooring.<\/span><\/span><\/span><\/p>\n

This successful launching project with marine airbags was not only\u00a0regarded as world record of airbag ship launching, but also means “Evergreen Maritime are moving forward and growing.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
