Software Datasheet

DeepVIV™ Vortex Induced Vibrations analysis software

Applications Flexible risers, umbilical

Production and drilling rigid risers

Hybrid riser concepts including riser base jumpers

Towed systems

Analysis process A preliminary modal analysis must be carried out

with DeepLines. The modal analysis model may

include complex models with several lines connected

together to properly handle interaction effects.

DeepVIV is automatically plugged with modal

analysis results database produced by DeepLines.

Selection of modes based on mode shapes and

locking criteria is automated.

Current profiles may be defined either from the GUI

or from text files to run series of VIV analyses with

several current profiles

Calculation of steady state VIV response through

energy bnlance for each mode

DeepVIV is part of the marine software

solutions developed by Principia and IFP

Energies nouvelles. The program predicts

the response of marine structures such as

risers and cables to Vortex Induced

Vibrations (VIV). The program uses a

modal superposition approach to derive

the VIV response of the structure in

uniform or sheared currents. DeepVIV is

integrated in DeepLines finite elements

software package and is marketed as an

optional module to DeepLines.

Main features DeepVIV is a VIV response analysis software based

on modal superposition approach.

Handles both constant and sheared current profiles.

Handles cylinders of non-constant section (variable

diameter, mass and stiffness) and strakes.

Based on modal analysis results produced by

DeepLines allowing to simulate complex models such

as riser towers, flexible and riser base jumpers.

Seabed contact with friction is properly taken into

account through preliminary modal analysis

Automated selection of modes based on modal

shapes with respect to current profile and lock-in

criteria. Low energy modes may be cut off.

User defined Strouhal number

The bandwidth of lock-in criteria on reduced velocity,

the drag and structural damping, may all be user-

defined.

Outputs cross-flow displacement amplitude, RMS

curvature, RMS stress and drag amplification factor.

S/N curves may be entered through DeepLines GUI

to derive damage rates for every current profiles

Modeling of sliding device including friction : J-tube,

guides, keel-joint, PIP…

External contact between lines for clashing analysis

Contact with any user-defined surface, either fixed or

moving (soil, moonpool, bellmouth,…)

User interface Convenient model setup through DeepLines GUI, no

need for spreadsheets to define input data.

Current Definition through DeepLines GUI or

external Excel sheet for multiple currents and

associated probabilities.

Definition of Stress Concentration Factor per

sections.

Definition of strake effect per sections.

Static and Modal analysis results (geometrical and

mechanical) available through DeepLines.

Modal shape visualization.

Specific outputs for DeepVIV including displacement,

acceleration, stress, curvature and damage along the structure.

Automated calculation of cumulated damage for

multiple currents based on Miner’s rule.

Validation DeepVIV is validated against comparison with

experiments and numerical results based on the following projects :

Hydlines JIP : comparison with experimental

results with variable pipe section in constant current.

STRIDE JIP : comparison with experimental

results from Allegheny TLP risers monitoring

DeepSTAR JIP : comparison of lift curves through CFD

Comparison with wake oscillator models

Comparison with CFD -structure coupled analyses
