www.seadiscovery.com Marine Technology Reporter 13 news The towing tank at the Davidson Laboratory - part of Stevens Center for Maritime Systems - has been a major force in maritime research since it opened in 1944. It re-opened recently after a 16- month expansion project. Some of the new capabilities will assist in: detecting attack- ers in ocean and harbor waters; protecting the shoreline from devastating storms and climate change; designing fast, stealthy ships for commerce, pleasure and national defense. Davidson Laboratory is located near the Hudson River shore in Hoboken, N.J., directly across the river from midtown Manhattan. "Today, we face critical chal- lenges - ranging from terrorist threats to natural disasters to the need to enhance trade and competitiveness through advanced technologies. All of those chal- lenges have a bearing on - and will be met by - state-of-the-art maritime research. We will be better able to address those chal- lenges with the knowledge created by the new tank, which will be the most advanced facility of its kind in the United States," said Hal Raveche, president of Stevens. The recently completed renovations have significantly enhanced the facility's capa- bilities. The Towing Tank is now 65 per- cent larger; it is equipped with better view- ing areas to allow researchers to visualize the effects of water on hull forms and shorelines; and it is equipped with a new Planer Motion Mechanism, which simu- lates complex lateral wave movements against a hull that is moving forward, modeling the full complexity of interac- tions between a ship and the ocean. The expansion and renovation was con- ducted with the help of funding from the U.S. Navy as well as a Department of Defense University Research Instrumentation Program (DURIP) award. "The U.S. Navy and the Defense Department are vital partners of the labo- ratory, and we are pleased that we are able to contribute to security through our research," Dr. Bruno said. "In an age of computer modeling, some- times there's still no substitute for physical testing, and the Towing Tank allows us to conduct it with a high degree of accuracy," Dr. Bruno said. The Towing Tank will be engaged in major projects, including: designing advanced multi-hull ships for the U.S. Navy; studying the impact of major coastal storms on the New Jersey shoreline in order to take steps to better protect it in the event of a Katrina-like hurricane; working with, America's Cup participant, Team Oracle to make their fast racing yachts even faster.
