System Integration
PCCI provided system integration services and documentation for the towed source, electronics, umbilical, and deployment winches. The 40-year old winches were significantly upgraded to handle the new fiber optic cabling, and the end connectors. Besides the addition of fiber optic junction boxes and connectors, new hydraulic power units and a remote control were added to the system. The GFE tow cables were trimmed to fit on the winches, the end connectors were modified to work with the new tow projector sources and control systems, and new anti-strum fairings were added to the cables.
PCCI prepared and delivered an operations and maintenance manual and drawing package addressing each component of the completed acoustic projector tow system
Testing and Calibration
The upgraded HLF-3 acoustic sources, topside controllers and associated cabling was tested and calibrated at the Navy’s Seneca Lake Acoustic Measurement Test Facility over a period of six days.
