# Mooring System Installation Methodology

For details of the code implementation, please see the
[Mooring System Installation API documentation](#mooring-install-api)

## Overview

The `MooringSystemInstallation` module simulates the installation of mooring
lines and anchors at site for a floating offshore wind project. The mooring
system installation is simulated using a multi-purpose support vessel that
transports the components to site and performs the onsite installation
procedures.

## Configuration

The primary configuration parameters available for this module are the
installation vessel and the mooring system configuration. An example of these
parameters is presented below.

```python
config = {


    "mooring_install_vessel": "example_support_vessel",
    "mooring_system": {
        "num_lines": 4,      # per substructure
        "line_mass": 500,    # t
        "anchor_mass": 500,  # t
        "anchor_type": "Drag Embedment",  # or "Suction Pile"
    }
    ...
}
```

## Processes

The default times associated with the installation procedure are listed in the
table below.

| Process                   | Inputs                                               | Default    |
