Eversafe marine engineering company is a professional team who engage in marine airbag ship launching and fender design. As a subsidiary company of Evergreen Maritime, Eversafe benefit from Group Company’s deep technical background and becomes the pioneer of industry. Eversafe contracted with CNOOC for two barges launch project recently.
The two barges named “Ocean oil 225” and “Ocean oil 226” with 8500 tons lightweights, 161 meters length, 31 meters width. The launching ramp is 178 meters long and 50 meters wide and its slope degree is 0.859.
The “Ocean oil 225” and “Ocean oil 226” are designed as deck barges; their empty gravity centers are far away from the central point. Evergreen engineers used 500 ton ballast water to adjust barge’s gravity center to the suitable position. People should know that for marine airbag ship launching the gravity center is very important to the success of launch. Then ballast water is the essential tool to adjust gravity center position.
Total 50 pieces Evergreen marine airbags (1.8 meter diameter and 18 meter long) rise up the barge first and adjust the barge’s gradient to demanded angle. At that time ropes from winch pull the barge from slipping. When water reached the wanted depth, ropes were break down to release the barge. Then barge went into the water smoothly by riding marine airbags and it total took 62 seconds from start to float.
CNOOC has a long-term supply from Qingdao Evergreen Maritime which includes boat fenders’ designing and supplying. Qingdao Evergreen Maritime is a professional manufacturer of marine airbags and boat fenders and well positioned to serve customers with a dedicated technical organization.
