Small-form Subsea Positioning Transponders

Kongsberg Maritime is introducing a range of mini medium frequency subsea transponders. With a smaller form factor, improved operational functionality and design and the use of modern materials the cNODE MiniS family supersedes the KONGSBERG Mini SSBL transponders (MST) range, which was first available in 2002. Expanding the well-established cNODE portfolio, the cNODE MiniS 34-180 and cNODE MiniS 34-40V are the smallest transponders for use with HiPAP, cPAP and µPAP underwater positioning systems, and are ideal for accurate Remotely Operated Vehicle (ROV) positioning operations. Both new cNODE MiniS transponders are depth rated to 4,000m and offer a diverse range of... (read more)

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...

USBL for Tidal Energy Positioning

One of the latest renewable energy sources currently being investigated for future large scale commercial deployment is tidal energy that exploits the natural ebb and flow of coastal tidal waters. As with other energy sources offshore, innovations to harness tidal forces often throw up additional operational difficulties particularly to do with positioning of the devices on the ocean floor and their connections to shore. Triscom have recently added the latest USBL positioning system, the Applied Acoustics' Easytrak Nexus, to its equipment pool to meet the increasing requirement for accurate underwater positioning tasks. Triscom is experienced in hydrographic/seabed survey and is... (read more)
