38 MTRavailable for high resolution and deep penetration geotechni- cal surveys in near shore or deeper water. ?We?re very excited about being able to offer this versatile equipment with its high standards of performance and numer- ous safety features to our clients. It complements the marine data acquisition options we have available to geophysical en- gineers investigating seabed characteristics,? said Tom Nicols, ?and we fully expect it to become a key ?workhorse?, supply- ing our customers with many of their seismic energy needs.? New Gyro Changeover System Teledyne TSS launched a new gyrocompass changeover sys- tem that protects navigation equipment against the danger of a sudden loss of heading input. The new system can be con- nected to up to four gyrocompasses and has been designed to automatically switch its throughput to that of another gyro should the principal one fail. The system can also be used to enable the manual changeover of gyro throughput if required, and the manufacturer claims it is currently the only system on the market that is capable of covering every failure situa- tion. The system consists of a rugged, bulkhead-mounted en- closure for the retransmission circuits and up to two separate display units that employ touch screen panels to provide the user interface. The availability of two displays enables rapid operator intervention at key locations on the vessel. The LED TFT panels show the condition and performance of all gyros in use and provide all of the operational controls in a clear format to permit immediate interpretation of the alarm and equipment status. The status and alarm interface is designed to comply with DNV rules for nautical safety which specify that no single failure shall result in a loss of heading infor- mation to receiving devices. With 16 IEC 61162 serial data outputs, the new changeover system is particularly suitable for use with Teledyne TSS Meridian gyro compasses. It can also be used to undertake the changeover of any other makes of gyrocompass that use the same data output formats should they fail. It also has the option of enabling one channel to be reformatted if necessary. www.teledyne-tss.com Sonardyne Aids NOC Sonardyne International Ltd.?s Ranger 2 USBL acoustic po- sitioning system played a role in the recent discovery of the People, Company & Product News from Ocean Business Tom Nicols of Geomatrix left, receiving his new seismic power supply, from Applied Acoustics?
