Sonardyne for Cascade Chinook Development
BMT Scientific Marine Services selected Sonardyne to supply an integrated acoustic positioning and telemetry system for Petrobras America's Gulf of Mexico Cascade Chinook field. The system forms part of an extensive life-of-field integrity monitoring system for five Free Standing Hybrid Risers (FSHRs) The Cascade Chinook field development is the first use of an FPSO (Floating Production Storage and Offloading) system in the Gulf of Mexico. All risers, umbilicals and monitoring system transceivers are integrated into a turret buoy which can be disconnected from the FPSO allowing it to move off-station when there is a threat to the facility. The turret buoy is fitted with a number of transceivers to ensure a line of sight to each riser tower without obstruction by the risers or mooring lines. These transceivers are controlled by BMT's monitoring system in the FPSO's turret to acquire position, sensor and
load monitoring data. In the event of a disconnection the system continues to record data which can later be downloaded by the FPSO or another vessel. The system uses Sonardyne
Wideband signal architecture that enables remote high speed and reliable data communications through water.

Cable CAD Assists HL-Technologies
Cable Systems design and manufacturer HL-Technologies sought to raise the standard on cable design and analysis through the purchase of the software package, Cable CAD. The software is designed to allow the engineering teams to efficiently perform FEA analysis of their cables at design level, with little or no production being necessary. Anticipated performance and overall characteristics of a
54 MTR
design can be reviewed by the client, as well as the impact certain changes in design would have. Less production results in less cost for the client and due to the level of technology the software provides, analysis accuracy is high.

New Scanning Sonars & Profilers
Subsea Kongsberg Maritime was scheduled to debut two new sonar
products from its sonar division, Kongsberg Mesotech Ltd. The 1171 Series is a complete range of multifrequency, fast scanning obstacle avoidance imaging and profiling sonars, which have been developed to meet the requirements for both shallow and deep ocean applications. The dual transducer design allows optimized operational configuration for both long range obstacle avoidance and shorter range imaging detail. The transducer is protected
