The Beach Laboratory also serves as the operational facility for all field research activities of the center.
Shown below are the floating test platforms for static immersion testing and the new dynamic immersion test facility. For more detailed information about the tests and the test site, please click HERE.
Marine Coatings Exposure Facilities. The degradation of the marine ecosystem comes from a wide range of pollution sources. Among the most devastating chemicals come from the toxic compounds (biocides) used in marine paints that are added to prevent the attachment of barnacles, algae and other fouling organisms on the bottom of the hull of ships and other submerged surfaces. The use of tributyl tin (TBT) as marine toxicant was banned by the International Maritime Organization of the United Nations in 2003. Many more toxic chemicals remain in use. And, until such time that nontoxic alternatives are developed, these biocides will continue to cause pollution in the oceans.
The development of research facilities to study marine paints and nontoxic additives are part of the long term program to identify potential natural compounds that may be used to replace biocides in current commercial use. To determine the performance of novel nontoxic coatings and additives, exposure platforms had been built within the protected cove of Karrapad, where aggressive year-round fouling of submerged surfaces by barnacles are naturally present. Static immersion and dynamic test platforms are available to enable simulation of the performance of coatings under natural conditions. For more information about this research, please click HERE.
Leach Rate Analysis. Marine paints are among the major sources of pollution of the oceans. This results from the leaching of biocides and heavy metals from the submerged portions of the hull as the ship travels or while in port. Thus, the measurement of the release of copper, zinc and other biocides from marine paints is important in determining not only the efficiency of the marine paints, but also its environmental consequences.
Collaborations. SHMRC has long term collaboration with Poseidon Sciences Group, a US research and development corporation. This collaboration, which began in 1994 has continued to this date.
