Mooring System Installation Methodology

For details of the code implementation, please see Mooring System Installation 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.

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"
    }
    ...
}
