Jacket analysis

This example involves using Sesam Manager, GeniE, Wajac, Sestra, Splice, Framework, Stofat and some auxiliary programs. It includes several analyses of a 4 legged jacket:

• Static (ULS) analysis of jacket fixed at sea floor
• Free vibration (eigenvalue) analysis of fixed jacket
• Static (ULS) analysis of jacket with piles
• Linearising piles and soil replacing them by linear springs
• Free vibration (eigenvalue) analysis of jacket with linear spring support
• Deterministic fatigue analysis
• Spectral fatigue analysis based on static structural analysis
• Spectral fatigue analysis based on dynamic structural analysis
• Spectral fatigue analysis based on equivalent static loads structural analysis
• Stochastic fatigue analysis based on dynamic structural analysis (pure beam model)
• Stochastic fatigue analysis based on dynamic structural analysis of tubular joints converted to shell models
• Earthquake analysis
• Transportation analysis with pre-stress

Import the ZIP file into a new Sesam Manager job. A document explaining the analyses is included. Select the job and go to Attachments (tab to lower right in Sesam Manager) to find this and other files related to the example.

This example involves using GeniE, Wajac, Sestra and Splice.

Unzip the downloaded example file and Import the Model_Start.gnx into a new GeniE workspace. This example includes:

• Running wave pile soil analysis
• Creating capacity model
• Performing code check for beam and joint
• Create a report for code check
• Redesign

A document explaining the procedure and step by step instruction is included.

This example is about Eigenvalue Analysis for a jacket structure using GeniE and Sestra. It is recommended to use the latest version of GeniE and Sestra for this task.

This example shows how to use Usfos to do a pushover collapse analysis of a jacket. The jacket is subjected to gravity and buoyancy plus a wave that is scaled (unrealistically) to provoke a pushover collapse. The input to GeniE to create the model and run analysis activities is provided. Manual steps are taken to export the model from GeniE to Usfos and to do some minor adjustments to the Usfos input. A document attached to the job explains how to do this.
