Moorings are one of the more vulnerable components of an offshore system. Many mooring failures go unreported, and those that have a consequence and need to be reported give an impression of high levels of unknown risk. This talk will summarize our recent research on synthetic mooring lines commonly seen in Blue Economy applications, including aquaculture, marine energy and floating wind energy. We will discuss nonlinear time dependent stiffness behavior caused by linear and nonlinear viscoelastic properties of the materials. We will also present ongoing work on effects of biofouling and development of smart rope technology for condition monitoring.


Krish Thiagarajan Sharman is an Endowed Chair in Renewable Energy & Professor in the Department of Mechanical & Industrial Engineering, University of Massachusetts Amherst. He holds a Ph.D. in Naval Architecture and Marine engineering from the University of Michigan, and has been an academic at various universities in Australia and the U.S. over the past 25 years. His areas of interest focus on design and fluid-structure interaction analysis of floating offshore wind systems, wave and tidal energy systems, coastal food production systems and offshore platforms in general.
