ORBIT - Release v1.2

Enhancements:

In this release there were updates to ORBIT's cost model. Users can expect to see different CapEx results because of:

  • Soft CapEx Methodology consistent with https://www.nrel.gov/docs/fy16osti/66579.pdf. Users can still specify a $/kW for all any CapEx categories.
  • Common Cost (defaults) now employs a similar approach to NYSERD to adjust ORBIT's common costs (a.k.a default values) based on publicly available commodity indices. We updated all the common costs (design costs, cable, vessel day rates, project parameters, soft cost) to be updated as of 2024 dollars. See #187.

Improvements:

Some infrastructure needed a few fixes.

  • The WISDEM API that connects ORBIT to WISDEM was out of sync and had some variable naming errors. See #183.
  • Updated ParametricManager to be compatible with latest version of python-benedict See #189. User's should rebuild their environment.

Bug Fixes:

There was a units error in the characteristic impedance calculation that effected the power factor and ultimately determined how much power an HVAC cable can support. Note that HVDC cables were unaffected by this bug. With this fix, the AC power that each cable can handle is lower which means fewer turbines can be connected on the same array cable. See #186 for more detail on the issue and #188 for the PR.

New Feature:

ORBIT - Updated Beta Release

  • Vessel mobilization added to all vessels in all installation modules.
    Defaults to 7 days at 50% day-rate.
  • Cable lay, bury and simulataneous lay/bury methods are not flagged as
    suspendable to avoid unrealistic project delays.
  • Cost of onshore transmission construction added to
    ExportCableInstallation.
  • Simplified ArrayCableInstallation, ExportCableInstallation modules.
  • Removed pandas from the internals of the model, though it is still useful
    for tabulating the project logs.
  • Revised package structure. Functionally formerly in ORBIT.simulation or
    ORBIT.vessels has been moved to ORBIT.core.
  • InstallPhase cleaned up and slimmed down.
  • Environment and associated functionality has been replaced with
    marmot.Environment.
  • Logging functionality revised. No longer uses the base python logging module.
  • Vessel now inherits from marmot.Agent.
  • Tasks that were in ORBIT.vessels.tasks have been moved to their
    respective modules and restructured with marmot.process and
    Agent.tasks.
  • Modules inputs cleaned up. type parameters are no longer required for
    monopile, transition piece or turbine component definitions.
  • Removed old/irrelevant tests.
