- •
The movement of riser upper end causes the oscillation of riser lower end.
- •
The oscillation of riser lower end brings about the connection difficulty.
- •
Movement optimization via ACO algorithm endeavors to reduce the oscillation.
- •
Tank experiment of a riser model confirms good efficiency of the optimized movement.
- •
Numerical analysis of a 1500 m flexible riser shows good efficiency of the optimized movement also.
