Major Savings Through Acoustic Positioning

CSA International Inc, an environmental survey company working in the Gulf of Mexico, has become the first organisation in the world to purchase a new ‘calibration-free' acoustic positioning system launched by Sonardyne International Ltd. The GyroUSBL (see image) integrates Sonardyne's Lodestar Attitude and Heading Reference System (AHRS) and sixth generation (6G) Ultra-Short BaseLine (USBL) transceiver into a single unit and was shown to offer operational benefits during a deepwater ROV survey carried out earlier this summer.   Most USBL positioning systems need to undergo a calibration process to determine the precise alignment offsets between the acoustic transceiver and the vessel's...

Dredge Efficiency and Precise Positioning

Integrating Dredging and Hydrographic Techniques
Dredgers involved in mining for (precious) minerals and metals often work in an inland dredging pit. Dredgers float in a ‘wet environment’ where the surrounding water is used as transport medium. The fact that the minerals are mostly covered in various sediments is one of the biggest problems in mining them. This article describes some of the techniques used in these dredging operations and illustrates the importance of integrating techniques and information. Most minerals, like rutile and zirconia, are to be found on top of a layer of clay with the highest concentrations found closest to it. Pewter is mostly... (read more)

Underwater Positioning Systems and Transponders

Kongsberg Maritime has launched during OTC a new range of acoustic underwater positioning systems and transponders, designed to harness the power of 'Cymbal' signal processing protocol whilst also being backwards compatible with the HPR 400 protocol and analog transponders. Other systems on display at OTC include HiPAP 501/451/351/351P, which are the second generation acoustic underwater positioning system offering improved position accuracy, longer range capability and faster data telemetry.  The new cNODE series of transponders consists of three models: Maxi - a full size transponder with large battery capacity, floating collar and release mechanism, and long life operation, designed primarily for...

TerraStar Positioning for Dredging Operations

DEME, Belgium, has commissioned TerraStar GNSS’s TerraStar-D Precise Point Positioning (PPP) service to support the worldwide near-shore operations of its multifunctional fleet of dredgers and auxiliary vessels. Operating in conjunction with Septentrio AsteRx2eL GNSS positioning and AsteRx2eH heading receivers, the TerraStar-D service will provide DEME’s vessel fleet with seamless high-precision decimetre-level accuracies using a combination of GPS and Glonass satellites to ensure faster levels of convergence and high update rates in the most demanding environments. Selection of the specialist service follows extensive trials under the auspices of DEME’s Survey Department during which recurring real-time accuracies were also shown to be... (read more)
