Qingdao Yongtai assisted the launch of a liquefied gas carrier in the Pacific Ocean

On September 28, 2011, Yongan Shun Ship Engineering Co., Ltd., a subsidiary of Qingdao Yongtai Airbag Engineering Co., Ltd., successfully launched a 5000 cubic liquefied gas carrier for Pacific Offshore. The ship has a vertical length of 92.5 meters, a width of 17.4 meters, a self-weight of 2,230 tons, a draught of 3.87 meters, and an abdomen of 0.74 meters.
Pacific Offshore and Luxembourg Jaccar Holdings signed a contract for the construction of six 5000 cubic meters full-pressure LPG vessels. Up to now, there have been 5 constructions. The launch of the launch of the first ship has a number of innovative designs, including a more environmentally friendly double-shell double-bottom structure, a larger space dual-body tank design, a highly maneuverable ship type, and an automated one-person pilot cabin.
The ship was built on the No. 3 shipyard of Lianxinggang Shipbuilding. The ship's platform is divided into two sections. The first section is 130 meters. The slope is k=1.3/100, the second section is 19 meters, the slope is 2.5/100, and the end of the berth is 3.635 meters.
Due to the thinness of the ship's shape and the high elevation of the ship's platform, there is a certain risk of collapse in the launch of the airbag. Qingdao Yonganshun Company carried out detailed calculations for the launching project, and negotiated with the shipyard and shipowners several times to finally establish a safe launching plan.
On September 26th, Qingdao Yongan Shun engineering personnel stationed in Lianxing Port for shipbuilding and began to prepare for the intense work. From the top of the airbag to the withdrawal of the pier, the operator is meticulously carried out in strict accordance with the plan. In order to ensure the accuracy of the calculation of the launching water, Yongan Shun engineers measured the water level and the ship's data in the field, and revised the launching plan based on the measured data. On September 28th, after the successful completion of the preparatory work, Yongan Shun Engineering Company carried out the displacement work on the 5000 cubic liquefied gas carrier. When the ship arrived at the scheduled launching position, the engineer began to adjust the first airbag pressure so that the hull angle reached a predetermined angle. In order to monitor the change of the inclination of the hull in the launching project, the shipyard designed and installed the measuring equipment on the ship, and the person in charge was responsible for reading the recorded data.
At 12 o'clock on the 28th, the 5000 cubic liquefied gas ship launch ceremony was grandly opened, and the deputy mayor of Qidong City and the ship owner's ship inspectors delivered speeches respectively. At 12:30, the champagne broke at the bow, the traction wire rope was removed, and the hull slowly started with the airbag, and gradually accelerated, and finally smoothly floated into the water. The entire launching process took 40 seconds, and the maximum inclination of the hull monitored on the ship was 3.2°, which was in complete agreement with the calculation results.
The successful completion of the launching project was greatly assisted by Pacific Offshore and Lianxinggang Shipyard. From the design and implementation of the launching scheme, the technical personnel of all parties inspired and cooperated with each other and finally successfully completed the launching project. Qingdao Yongtai always adheres to the concept of leading technology and focuses on cultivating the technical comprehensiveness and comprehensive ability of engineering personnel. Through this launch, engineers and technicians have been greatly improved and improved from theoretical calculations to program execution.
