Next Generation of SHARPS Marine Sonic Technology, Ltd., work- ing in partnership with Hermetic Sci- ences, recently delivered components of the next generation Sonic High Accuracy Ranging and Positioning System (SHARPS) to Woods Hole Oceanograph- ic Institute. SHARPS is being used for positioning and control of the 6,500 m Jason/Medea ROV during missions where very high resolution position information is required. The new SHARPS uses spread spectrum signal processing to improve timing resolution, range perfor- mance and noise rejection. SHARPS will be available in standard as well as custom configurations to provide three dimen- sional positioning for ROV's, AUV's, and diver operations. MSTL plans to intro- duce SHARPS in February at Underwater Intervention 2005 in New Orleans. Circle 40 on Reader Service Card DMT Contracts With Perry Slingsby Perry Slingsby Systems (PSS) signed a contract with Deep Marine Technology (DMT) for the supply of two Triton XLS, 125 HP, ROV systems. The advanced work class ROV systems will form the basis for DMT's expanding ROV fleet and will be utilized on a worldwide basis. Both systems will be delivered in a heavy- work configuration, including 125 hp main power units, enhanced payload, heavy-weather handling systems and spare parts compliment for remote loca- tions. First system delivery is scheduled for February 2005. Circle 41 on Reader Service Card Side Scan Systems Drive EdgeTech EdgeTech Marine said its newest prod- uct, the 4200-FS Dual Mode Side Scan System, along with the strong sales of its 4300-MPX High Resolution/High-Speed Multipulsed Side Scan and 3200-XS model 512i Sub-Bottom Profiling Sys- tems, were the basis for such strong sales in 2004. The first of the 4200-FS Systems was delivered in August, and there has been a continuous shipping stream ever since. The 4200-FS offers two software selec- table modes of operation: High Definition Mode (HDM) for superior resolution and High Speed Mode (HSM) for dual pulse operation at up to 10 knots. An added fea- ture for the 4200-FS is its ability to get good resolution target data at over 200m per side on the high frequency. The 4200- FS has the ability to run over 6000m of coax cable and can be towed at above five knots without having to use a depressor. Circle 42 on Reader Service Card SeaBotix Unveils New System SeaBotix Inc. will introduce their Gen- eration 2 series of LBV systems at the beginning of 2005. The basic design of is unchanged, with changes lying in the components, both mechanical and elec- tronic. It was determined that the size of the LBV is ideal. The basis for this was an evaluation of size/weight or mass in con- junction with thrust and umbilical drag. Testing found that smaller designs do not have the required mass to overcome influ- ence caused by the umbilical making it difficult to hold a stable position with any amount of umbilical in the water. At 11kg the LBV is still very portable by a single person yet able to maintain a stable posi- tion with all its umbilical in the water. When combined with 150 m of umbilical LBV is actually lighter than its smaller competitors, due to the incredibly small diameter umbilical. In addition, the pow- erful standard thrusters are still able to propel the LBV to 2.75 knots and more along the surface. LBV is controlled by the operator and not by the umbilical. Enhancements found in the Generation 2 LBV systems include higher resolution sensors, finer controls, more open design for added power and simplified service, proportional vertical thruster control, more powerful thrusters, integrated con- sole standard and much more. All of the improvements have been made without a significant impact to pricing. Circle 43 on Reader Service Card Reson Debuts SeaBat 7128 Sonar Reson expanded its product line with the SeaBat 7128, a new Multibeam For- ward Looking Sonar. The SeaBat 7128 is a single and/or dual frequency (200/400 kHz) system and is available in depth rat- ings of 400 or 6,000 m. The system has been specifically designed for incorpora- tion in a variety of platforms, from surface vessel, ROV or AUV. Circle 44 on Reader Service Card Sonsub Completes First ROV Clamp Installation Sonsub used and seal tested the first ROV installed deepwater elbow clamp in the Gulf of Mexico. Working off the HOS Innovator with the Innovator 09 ROV, the clamp was used to repair two holes on a four-in. service line on a pipeline sled in 4200 fsw. Tasks for Sonsub included the design, manufacture, assembly and testing of the required equipment used to facili- tate the remote installation of the Team Industrial Services designed clamp; SIT testing of the clamp; and installation pro- cedures which enabled the ROV to float the 980 lb. clamp onto the elbow, install and torque the bolts and pressure test the clamp.
