Project overview:

Robust Stabilization of Subsea Power Cables using Nonlinear Energy Sinks

Awardee:

University of Michigan

Start Date:

Q2, 2023

Technical Challenge Area:

Electrical Power Systems

Completion Date:

N/A (Currently Underway)

Synopsis:

This project aims at feasibility study of a novel approach to robustly suppress subsea cable vibrations and increase the power transmission resiliency by using retrofittable passive Nonlinear Energy Sinks (NESs).

Target Outcomes:

A retrofit solution to significantly stabilize the offshore wind platform motions and at the same time to harvest the wind and wave induced vibrations.

Report of lab test for the feasibility of the proposed NES for subsea cable, compared with the baseline.
