Design of the NUSC (Naval Underwater System Center) Replacement TCP (transducer Calibration Platform) Mooring for Lake Seneca, Dresden, New York
1983
Seelig, William N
The Transducer Calibration Platform (TCP) of the Naval Underwater System Center (NUSC), Dresden, N.Y. consists of a barge (33' wide, 150' long, 4' freeboard) and a small transformer float connected to a shore power cable. The two point mooring for this facility failed in 1982 after many years of service and a temporary mooring was installed to moor the facility for approximately one year. The new anchoring system is a four point mooring that is similar to the nearby, but larger, SMP mooring. The mooring legs consist of drag anchors, chain, concrete sinkers, wire rope, buoys and lines for connecting the barge and transformer platform to the mooring. The mooring has been designed to give or act as a shock absorber if sudden or larger forces act on the TCP. For example, a front crossing the lake could produce rapid increases in the wind speed and the barge would move slightly in response to these forces. However, under normal operating conditions the leg design and specified pretension of 5 kips, the mooring will be rather 'stiff' with a watch circle of less than 10' for wind speeds below 20 knots.
