Numerical simulation of piggyback pipelaying under current loadings [PDF]

open access: yesMarine Structures, 2023
For piggyback pipelaying operations, current-induced force and its effect on the piggyback pipe have not been thoroughly studied. In the present study, an improved method in hydrodynamic load calculation and structural modelling is proposed to simulate ...

Steady current induced vibration of near-bed piggyback pipelines: Configuration effects on VIV suppression

open access: yesApplied Ocean Research, 2014
A series of experiments on steady current induced vibration of piggyback pipelines close to a plane seabed were conducted with a hydro-elastic facility in a conventional water flume.

Physical modeling and swirling strength analysis of vortex shedding from near-bed piggyback pipelines

open access: yesApplied Ocean Research, 2013
The vortex shedding from near-bed piggyback pipelines in a steady flow has been investigated experimentally in a large water flume. A specially arranged PIV system with upward-illumination of pulsed laser arrays from the flume bottom was employed for the

2010 IEEE 71st Vehicular Technology Conference, 2010
Piggyback is an effective way to reduce the MAC protocol overhead of wireless networks. This paper considers the physical data rate and transmission bit error to derive the criterion of piggyback. Numerical results show that the improvement of piggyback can reach 40% for some cases.

Piggyback archwires

Clinical Orthodontics and Research, 1999
Commonly, clinicians’ principal tool in the alignment phase of orthodontic mechanotherapy is the nickel‐titanium wire. During the course of orthodontic treatment, however, there are times when some segments of the dental arch require flexible wires, while the rest would benefit from rigid wires.
