ORBIT

Overview

The Offshore Renewables Balance of system and Installation Tool (ORBIT) is a model developed by the National Renewable Energy Lab (NREL) to study the cost and times associated with Offshore Wind Balance of System (BOS) processes.

ORBIT includes many different modules that can be used to model phases within the BOS process, split into design and installation. It is highly flexible and allows the user to define which phases are needed to model their project or scenario using ProjectManager.

ORBIT is written in Python 3.10 and utilizes SimPy’s discrete event simulation framework to model individual processes during the installation phases, allowing for the effects of weather delays and vessel interactions to be studied.
