We conduct research in methods new methods to improve deepwater monitoring and address installation of advanced sensors on ”already deployed” risers, flowlines, trees, and other deepwater devices. The research is part of the Clear Gulf Joint-Industry Project (JIP) that forms a collboration between [[http://astrotechnology.com|Astro Technology]], NASA, and various oil and gas companies. This partnership utilizes the test facilities and expertise of NASA for operating in remote environments and under harsh conditions. The objective of this collaboration is to jointly develop technology that minimizes impact on the environment, improves safety, and monitors critical energy infrastructure. A new area of application is the retrofitting of existing subsea structures with fiber optic monitoring sensors installed by divers or Remotely Operated Vehicles (ROVs).

Dynamic constraints may change constantly. Projects that have been completed are monitoring of operating conditions to avoid hydrate formation [1] and tendon strain monitoring for Tension Leg Platforms (TLPs) [2]. Advanced monitoring and control is performed with the [[http://apmonitor.com|APMonitor platform]] for analyzing large-scale and complex systems such as these subsea structures.
