Turbine Installation

For detailed methodology, please see the Turbine Installation methodology documentation

TurbineInstallation class and related processes.

class ORBIT.phases.install.turbine_install.standard.TurbineInstallation(config, weather=None, **kwargs)

Standard turbine installation module using a Wind Turbine Installation Vessel (WTIV). If input feeder and num_feeders are not supplied, the WTIV will perform all transport and installation tasks. If the above inputs are defined, feeder barges will transport turbine components from port to site.

phase = 'Turbine Installation'

capex_category = 'Turbine'

expected_config = {'feeder': 'dict | str (optional)', 'num_feeders': 'int (optional)', 'plant': {'num_turbines': 'int'}, 'port': {'monthly_rate': 'USD/mo (optional)', 'name': 'str (optional)', 'num_cranes': 'int (optional, default: 1)'}, 'site': {'depth': 'm', 'distance': 'km'}, 'turbine': {'blade': {'deck_space': 'm2', 'mass': 't'}, 'hub_height': 'm', 'nacelle': {'deck_space': 'm2', 'mass': 't'}, 'tower': {'deck_space': 'm2', 'length': 'm', 'mass': 't', 'sections': 'int (optional)'}}, 'wtiv': 'dict | str'}

property system_capex

Returns 0 as turbine capex is handled at in ProjectManager.

setup_simulation(**kwargs)

Sets up simulation infrastructure, routing to specific methods dependent on number of feeders.

setup_simulation_without_feeders(**kwargs)

Creates the infrastructure for turbine installation without feeder barges.

setup_simulation_with_feeders(**kwargs)

Creates the infrastructure for turbine installation using feeder barges.

initialize_wtiv()

Initializes the WTIV simulation object and its onboard storage.

initialize_feeders()

Initializes feeder barge objects.

initialize_turbines()

Initializes turbine components at port.

initialize_queue()

Initializes the queue, modeled as a SimPy.Resource that feeders join at site. This limits the simulation to one active feeder at a time.

property detailed_output

Returns detailed outputs of the turbine installation.

ORBIT.phases.install.turbine_install.standard.install_turbine_components_from_queue(wtiv, queue, distance, turbines, tower_sections, num_blades, **kwargs)

Logic that a Wind Turbine Installation Vessel (WTIV) uses to install turbine componenets from a queue of feeder barges.

Parameters:
