Moreover, the dynamic responses of different parts are apparently connected, so the coupling effect cannot be ignored. The results show that the PLET position in different phases as well as the direction of wave and current during installation has great effect on forces and motions of the system parts.
The static and dynamic responses of each part in different operation phases and under different wave and current directions are analyzed.
#ORCAFLEX INSTALLTATION ANALYSIS SOFTWARE#
The proposed model is validated by OrcaFlex software and then used to carry out numerical simulations of PLET installation based on practical operations. The pipelaying vessel is controlled by a dynamic positioning system. The finite element method is proposed for the pipeline and the cable, while the hydrodynamic forces on the PLET are simulated by the Morison equation. The whole model mainly consists of four parts, which are the pipelaying vessel, the abandonment and recovery (A&R) cable, the pipeline and the PLET.
#ORCAFLEX INSTALLTATION ANALYSIS FULL#
To study the dynamic characteristics of the pipeline end termination (PLET) installation operation based on pipelaying under full coupling effect, a numerical model for PLET installation based on S-laying with the vessel–cable–PLET–pipeline coupling in time domain is proposed in this study.
