Datasheet ORT and DORT Acoustic Release Transponders
Description Oceanographic Release Transponders (ORTs) and Deep Oceanographic Release Transponders (DORTs) are tough, reliable acoustic releases designed for deployment in either 2,000 metres or 6,000 metres of water. Key Features Safe Working Load of 1,275Kg (Options for heavier loads) 2,000 Metre or 6,000 Metre depth rated options Highly reliable release mechanism Up to 3 years deployment Excellent corrosion resistance The units are commonly used to moor oceanographic instrument strings on the seabed for periods of up to 36 months. However, their compact size allows them to be easily incorporated into subsea instrument frames or installed on towfish and AUVs to enable ballast to be dropped in an emergency. Compact and rugged design
Standard features include a Safe Working Load of 1,275Kg (at 4:1) and a spring-assisted release mechanism. This type of release mechanism was originally developed by Sonardyne for navigation transponders supplied to the offshore industry of which there are now many thousands reliably in service around the world.
ORTs and DORTs are controlled using frequency band specific Lightweight Command Units (LCU) which comprises of a dunking transducer connected either to a spray-proof Psion or, via supplied software, to any PC. For security of operation, a special coding system provid……
