Part of Sonardyne’s Coastal Acoustics product range, the Type 7986 Lightweight Release Transponder (LRT) has been developed from transponders capable of accurately positioning hundreds of seismic receiver nodes.
It has both receive and transmit functions, unlike similar low-cost release transponders, enabling accurate slant ranges to be measured, release actuation to be confirmed and its position to be accurately determined.
The LRT is depth rated to 500 metres making it the ideal choice for use in continental shelf waters. Field replaceable alkaline or long-life lithium battery packs give a listening life of 18 months and 51 months respectively.
Part of Sonardyne’s Coastal Acoustic Product Range, the Type 7967 OBC/LRT Deck Unit is used to command and programme Sonardyne’s range of TZ/OBC transponders and Lightweight Release Transponders (LRTs).
It comprises of a deck unit and dunking transducer supplied with 10 metres of cable.
The deck unit is used initially to program the acoustic identity of the transponder, test the transponder and, in the case of the LRT, load the release ‘bit’ prior to deployment.
Once deployed, it can be used to measure ranges to the transponder and prior to sending a secure release command, relocate the transponder.
Part of Sonardyne’s Coastal Acoustic product range, Homer-Pro enables divers to quickly and easily relocate targets in low and zero visibility from over 750 metres distance.
By using small acoustic transponders to mark points of special interest, for example, wrecks and pipelines, a diver can swim directly to a location, thereby reducing wasted dive time.
Homer-Pro comprises of a diver held relocation device and low cost marker transponders which are deployed at the target locations. Each transponder has its own unique ‘address’ code, enabling a number of targets in a small area to be marked and relocated unambiguously.
LIGHTWEIGHT TAUT WIRE DP REFERENCE SENSOR
Designed for use as a deck mounted DP reference System on vessels of opportunity or as a permanent installation, the SMT TW-1.0 system gives very accurate measurements of a vessel’s movement referenced against the position of a 460kg depressor weight on the seabed.
A constant tension, heave compensated electric driven winch positions the depressor weight on the seabed, using a full vector controlled variable speed drive for precise adjustments. Small vessel movements in all axis are measured by a gimbal head sensor and updated measurements are sent to the DP system via a programmable automation controller.
A compact footprint, mobilisation ready design and multi interface outputs means the TW-1.0 system is the Taut wire system of choice.
The MAGNETO® MX3D UW is an excellent low logistics multi-channel system for magnetic measurements of soil structures in marine and offshore applications.
The system is equipped with high-resolution FGM3D UW 3-axis Fluxgate sensors, having a sampling rate of up to 10,000 Hz.
The sensor data is digitized with 24 Bit by the cascadable data acquisition unit MX3D UW and allows connecting a multiple of five sensors.
The STR SeaVision IPZ underwater camera delivers high performance HD-IP video solution with advanced functionality, including remotely adjustable zoom & focus, wide angle water-corrected lens and internal data storage.
SATELLINE-EASy Pro is an IP67 (NEMA 6) classified UHF radio modem with a high power (up to 25 or 35 W) transmitter and wide 70 MHz tuning range.
It is designed for easy mobile use in demanding field conditions. According to the IP67 standard, the casing and connectors of the SATELLINE-EASy Pro are waterproof and secured against dust.
In addition to the high output power and wide tuning range, the channel spacing is also selectable to be 12.5, 20 or 25 kHz.
The SATELLINE-EASy Pro is equipped with a Liquid Crystal Display (LCD) and a keypad, used to indicate the current operating status, as well as for changing the operating channel and power level of the radio modem.
