Floaters

This workshop addresses how to perform a plate code check for yield and buckling, based on DNV Rule, in GeniE. The yield check is performed against DNV-RU-SHIP Pt.3 Ch.7 Sec.3 and the buckling check is performed against DNV-RU-SHIP Pt.3 Ch.8 Sec.4 / DNV-CG-0128 Sec.3 CFM.

It includes:

• Model preparation - corrosion addition, structure type, mesh and design condition
• Running structural analysis and result check
• Performing yield check (plate & beam yield)
• Performing buckling check (plate & stiffener buckling)
• Making a plate code check report

A GeniE GNX workspace file is used. The attached description explains all the steps to do the workshop.

This workshop addresses how to perform a DNV-RP-C201 Sec.6.4 - SCM2 buckling check and a DNV-OS-C101 element yield check.

Chapter 1 demonstrates an automated workflow that can be easily performed in GeniE. Chapter 2 is optional and provides a detailed step-by-step procedure including inputs and outputs, using a workflow managed in Sesam Manager.

It includes:

• Chapter 1: Performing RP-C201 Buckling Check in GeniE
• Chapter 2: Performing RP-C201 Buckling Check and OS-C101 Yield Check in Sesam Manager
  • Running analysis, exporting model and result file in GeniE
  • Exporting buckling capacity model from GeniE
  • Performing buckling check using Sesam Core
  • Performing yield check using Sesam Core
  • (Import the ZIP file into a new Sesam Manager job. The attached document describes all steps required to complete the workshop.)

This tutorial provides a comprehensive guide on creating and automating the parametric modelling of a spar-type floating offshore wind floater using GeniE and HydroD software. It covers:

1. Panel Model Creation in GeniE: Step-by-step instructions for manually and automatically building the floater hull's panel model.
2. Hydrodynamic Analysis in HydroD: Setup for frequency-domain hydrodynamic analysis using the panel model, including automation of the operations.
3. Automation with Sesam Manager: Integrating GeniE and HydroD operations into a single automated workflow for efficient parametric studies.

Ideal for users familiar with GeniE and HydroD, this tutorial simplifies the process of converting models into parametric scripts, enabling advanced hydrodynamic analysis and motion studies.

A .pln file is required for a Wasim analysis (time domain hydrodynamic analysis). This workshop introduces how to create a .pln file in GeniE and how to check it in HydroD.

The following topics are covered:

• Creating a .pln file for a FOWT substructure in GeniE
• Reading the .pln file in HydroD
• Checking the .pln file and make modifications in HydroD

Recommended minimum program versions:

• GeniE 8.11
• HydroD 7.2

This example involves using Sesam Manager, GeniE, HydroD, Postresp, Sestra and Xtract. The example demonstrates how to do a hydrodynamic analysis followed by a structural analysis of a floating object. Analysis of a condition with water-filled compartments is also included. Import the ZIP file into a new Sesam Manager job. Read the PDF document attached to the job.
