HIS LATEST ISSUE of Baseline is designed to coincide with one of the most
important dates in Sonardyne’s calendar; the bi-annual Oceanology International exhibition in London. For three days in March, we present our latest technological developments to the gathered audience of industry professionals from around the world. For those of you who will make the journey to OI this year, applications for our successful Wideband technology will form the major theme of our stand (No. 926) which will be divided into themed zones. But don’t worry; if you can’t make it to the show or are reading this magazine after the event, you’re not missing out. Many of the products and technologies making their debut at OI, are showcased right here in Baseline Issue 3 and at the many other events we will be exhibiting at during 2008. Our website has our full show calendar. Building upon the USBL optimisation article in Issue 2, we explain on Page 16 how to achieve unrivalled performance from your Sonardyne Wideband® USBL system by integrating it with a Lodestar AHRS. When operating Wideband systems in the presence of other acoustic systems, users need to be aware of the issues surrounding frequency management. In an interview with Sonarydne’s new Survey Customer Support Group (Page 18), we reveal how appropriate planning in advance of operations beginning, can avoid problems arising in the field. In general news, we report on deep rated Compatt 5 transponders heading for the Gulf of Mexico and a new system for LNG tankers that allows them to quickly and accurately relocate submerged turret buoys. We hope you enjoy reading Baseline 3 and as always, look forward to hearing from you soon.
