In February 15, 2017, Guangzhou Shipyard International Co. Ltd. of Dalian COSCO Shipping Co. oil transportation company built 50 thousand tons of refined oil / chemical tanker D type boat No. 2 plant in Nansha No. 1 shipbuilding platform, through the car shift to a semi submersible barge mode launching. This is the first ship of GSI launched after the Spring Festival, is the second ship Nansha factory production line put into operation after the platform launched.

Launch operations by the GSI joint Guangzhou Salvage Bureau, the Ninth Design and Research Institute of Engineering Limited company. The first ship by ship to the 9th through the development of 74 sets of 250 tons of ship lift car will hold the whole ship, and then along the platform line 4 rail longitudinal displacement to Guangzhou salvage operation for lifting 15500 tons of semi submersible barge on sitting pier, the semi submersible barge dive ship after float by tug towed to the mooring.
It is reported that the launch operations by summing up the experience the first boat, optimize the operation process, which will be divided into three groups of original car layout is changed into four groups, the hull stress is more uniform, improving the safety coefficient in the process of operation, also greatly shorten the operation time. The first ship launching process (the whole ship lift, over barge, sit pier) with about 24 hours, the launching process is only used for 10 hours.
Supporting the production line of the GSI platform this ship car system for domestic first self-developed ship car manufacturing shift, the cost is only the same type imported ship car system 40%. In the development and use in ship departemnt cooperation party GSI, inspection after two consecutive boat operations, and fully proved that the car system has reliable performance, excellent quality. Part of the car also has a three-dimensional adjustment function, the lifting device can not only achieve the upper and lower, before and after the adjustment, but also to achieve about 50 mm fine tune.

According to the Ministry of construction of GSI related experts, the regulating function of 3D ship car system can realize the accurate positioning of large ship. In order to make full use of this equipment, the next step is also planned to use this equipment to carry out a large ring of the main segment, improve the carrying efficiency.
