Mooring System Installation Methodology

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

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"
    }
    ...
}
