Orcaflex Installation Analysis
When to Use
- Subsea structure installation analysis
- Pipeline/umbilical installation sequences
- Heavy lift crane operations
- Installation depth variation studies
- Lowering phase analysis
- Splash zone analysis
- Installation feasibility assessment
- Crane wire and sling configuration
Prerequisites
- OrcaFlex license (for simulation)
- Python environment with
digitalmodelpackage installed - Reference model files (.yml format recommended)
- Reference elevation configuration
Python API
Generate Installation Depth Models
from digitalmodel.orcaflex.orcaflex_installation import OrcInstallation
# Initialize
installer = OrcInstallation()
# Configuration for depth variation
cfg = {
"structure": {
"BaseFile": "reference.yml",
*See sub-skills for full details.*
### Simple Depth Model Generation
```python
from digitalmodel.orcaflex.orcaflex_installation import OrcInstallation
installer = OrcInstallation()
# Simpler configuration
cfg = {
"reference_elevation_file": "models/reference.yml",
"structure": "Subsea_Template",
"masterlink": "Lifting_Point",
*See sub-skills for full details.*
### With Structure Orientation
```python
from digitalmodel.orcaflex.orcaflex_installation import OrcInstallation
installer = OrcInstallation()
# This generates:
# 1. Base model at each depth
# 2. Orientation variant (rotation about Z)
cfg = {
"structure": {
*See sub-skills for full details.*
