On 16th.Jan.2010, the 32,500DWT Bulk Carrier “NO. 6 Dongze” was successfully launched by Evergreen ship launching team with Evergreen Marine Airbags in Nanjing Dongze Shipyard. It is the sixth ship launched by Qingdao Evergreen Maritime Company using airbag launching technology for this shipyard.
This Bulk Carrier with 210 meters length and 34 meters molded breadth weight 9,500 tons. January is the dry season of the Yangtze River Valley, so there is long distance between the stern with the tide point. Fortunately the launching slipway was initially constructed in the light of Evergreen team’s design, so the calculation of launching start point came to be easier. Finally the ship was moved forward about 30m to reach the best launching point by the control of mooring winches.
Total 64 pieces Evergreen Marine Airbags D1.5xEL18 (YT-6) were employed to launch this Bulk Carrier. And all airbags’ inner pressures were adjusted to the required value before the launch. After a simple ship launching ceremony, the workers cut off the wire ropes to release the ship. Then the Bulk Carrier went into river by riding marine airbags smoothly. Different from the traditional end-on ship launching, the “stern dipping” and “stern rising” phenomena are not obvious anymore during airbag ship launching.
Qingdao Evergreen Maritime is preparing another 55,000DWT vessel launching project which will be performed after three weeks. Keep an eye on our website www.evergreen-maritime.com to know the latest news.
