Initial Characterization of the NREL Large Amplitude Motion Platform (LAMP)
The Large Amplitude Motion Platform (LAMP) at the National Renewable Energy Laboratory (NREL) Water Power Technology Validation Facility is a six-degree-of-freedom (6-DOF) motion platform intended to be used for dry testing of wave energy converters (WECs) and other marine energy devices.
This MHKDR submission contains data collected during an initial characterization of the LAMP. The intent of this characterization was to run the LAMP through a series of gradually more complex motion profiles to understand how the LAMP performs when it is pushed to and beyond the limits specified by the manufacturer. The data collected during this characterization is provided in this submission along with documentation of the provided data including a test log detailing the specifications of each individual test run, a data set description "NREL LAMP Characterization Dataset Description-v001.html" detailing the contents of the command and response datasets, a command dataset that includes multiple generated motion profiles, and a response dataset that contains a subset of the LAMP output including the commanded and response 6-DOF position, velocity and acceleration. This dataset is intended to be used by researchers and developers working on marine energy devices to prepare for testing on the LAMP by understanding the required LAMP data inputs and expected outputs.
The data generated during this characterization was collected using the LAMP built-in data acquisition system. The data was originally recorded in a proprietary binary format and has been converted to Parquet format for ease of use. The data has been filtered to only include 6-DOF motion inputs and outputs.
