The immersed
pipe transportation and installation ship used in Shenzhen-Zhongshan
link immersed tunnel project accomplished immersed pipes connection and
outfitting in the secondary outfitting area of Guishandao prefabrication plant.
In severe environments such as typhoon, the immersed pipe transportation-installation rig is easy to collide with the bank wall of the
secondary outfitting area. To avoid this phenomenon, the computational fluid
dynamics method is used to calculate the wind and flow loads of immersed pipe
transportation-installation rig, and the mooring system
of immersed pipe transportationinstallation rig under
the influence of typhoon environment in outfitting area is simulated using
threedimensional potential flow software AQWA.
Additionally, the motion response and mooring cable tension of the immersed
pipe transportation-installation rig under the combined
action of wind, wave, and current are calculated and analyzed in the time
domain. The calculation results show that the immersed pipe transportationinstallation rig docks in the secondary outfitting area will not
collide with the bank wall of the secondary outfitting area without closing the
dock gate when adopting the recommended mooring system in case of typhoon of
grade 10 or lower, and the dock gate should be closed to ensure the safety of
windlass in case of typhoon higher than grade 10.
