# DTOcean

**DTOcean is an open-source tool for design and techno-economic assessment of
marine renewable energy arrays.**

DTOcean can calculate:

- Optimal ocean energy converter (OEC) positioning
- <del>Energy export infrastructure</del>
- <del>Station keeping requirements based on OEC performance and site conditions</del>
- <del>Installation planning with weather effects</del>
- <del>Maintenance planning, simulating OEC downtime</del>
- <del>Environmental impact assessment (experimental)</del>

And features include:

- A unique statistical approach to calculating levelized cost of energy (LCOE)
- <del>OEC reliability influenced at component level</del>
- Graphical user interface
- Persistent database

(Features currently unavailable but planned for reimplementation are struck out.)

## Installation

Install the DTOcean suite of packages using pip:

```sh
pip install dtocean
```

After installation, download necessary data files and setup desktop shortcuts
using the following command:

```sh
dtocean init
```

## Database

See the [dtocean-database](https://github.com/DTOcean/dtocean-database)
repository for download and installation instructions.

## Usage

Open the DTOcean GUI using the DTOcean shortcut or from a command prompt:

```sh
dtocean app
```

### Command Line Tools

The `dtocean` command provides universal access to the command line tools for
all of the install modules. Documentation for each subcommand can be found in
the table below.

| subcommand    | help                                                     |
| ------------- | -------------------------------------------------------- |
| init          | Run module initialization (requires internet connection) |
| app           | See [dtocean-app]                                        |
| core          | See [dtocean-core]                                       |
| database      | See [dtocean-core]                                       |
| docs          | See [dtocean-docs]                                       |
| hydrodynamics | See [dtocean-hydrodynamics]                              |

### Example Files

The `examples` archive (in zip or tar.gz format) can be downloaded from the
[latest release](https://github.com/DTOcean/dtocean-examples/releases/latest)
of the [dtocean-examples](https://github.com/DTOcean/dtocean-examples/)
repository. See the "Getting Started 1: Example Project" chapter of the
[docs](https://dtocean.github.io/dtocean) for usage instructions.

## Documentation

See [https://dtocean.github.io/dtocean](https://dtocean.github.io/dtocean) for
the latest documentation. The documentation can also be accessed from the
`Help` menu of the GUI using the `Index...` command or using the `dtocean docs`
command line tool.

Various video tutorials can also be found on the Data Only Greater
[YouTube Channel](https://www.youtube.com/@dataonlygreater).
