The world's first stone riprap ship was successful

  • Detail

On December 14, the world's first X-Bow riprap ship built by Zhejiang Shipbuilding Co., Ltd. for van oord company in the Netherlands was successfully launched. This is also another important production node completed after the bankruptcy reorganization and restart of Zhejiang shipbuilding

the ship is e. its environmental benefits are 10 points significant 169. It is the first ship made in the world and is classified into Bureau Veritas (BV). The basic design is undertaken by USOs, and the detailed design and production design are carried out by Shanghai Institute of Ship Research and design (SDARI)

in September 2014, Jiangsu Pacific shipbuilding group signed a new shipbuilding contract with van oord of the Netherlands. In April, 2015, the world's first stone riprap ship E169 was officially built in Zhejiang shipyard. It was originally planned that this would be beneficial to detect materials with very large or very small elongation and obtain accurate experimental results. It will be delivered in 2016

the captain is 154.4 meters, the operating water depth is 600 meters, and can be extended to 1000 meters. The designed draft capacity is 12000 tons. The ship adopts the most advanced riprap technology and DP3 dynamic positioning system. There are advanced rockfall pipe riprap system and special ROV for riprap operation. The rockfall pipeline guides the stone to fall to the outer wall inorganic architectural coating jg/t 26 ⑵ 002 to the deep-water seabed. Through the guidance and cooperation of ROV at the end of the rockfall pipe, accurate riprap can be achieved

it is reported that the ship has obtained the clear classification symbol, as well as the symbol of the highest comfort level of comf nose 1 and comf VIB 1. On the one hand, the ship can be used for the suspension treatment before the laying of submarine pipelines and cables, the pretreatment of seabed before the installation of underwater structures, the pre riprap operations such as the support of submarine pipelines, on the other hand, it can be used for the post riprap operations such as the landfilling of pipelines and cables, the backfilling of trenches before digging the sun, the prevention of the floating, bending and deformation of submarine pipelines, and the ballasting of underwater structures. With the development of deep-sea oil and gas, the market prospect of this ship type is very broad
