OCEANOGRAPHIC MOORING SYSTEMS

Product catalog summary
Overview: The document discusses advanced mooring systems designed for oceanographic applications, emphasizing the use of aramid armor tape wrap for fish bite protection. It highlights the versatility and durability of these systems in various marine environments.
Specifications: The mooring systems offer traditional ropes and compound synthetic lines. Key features include positively buoyant rope sections without flotation devices, weighted sections with a lead core and polyurethane jacket, and compliant sections made from nylon or polyester. High modulus fibers provide high strength and low stretch.
Fish Bite Protection: Aramid armor tape wrap is used to protect against fish bites, ensuring the integrity of the mooring line. The document includes a photo from Woods Hole Oceanographic Institution showing the effectiveness of this protection.
Design Features: The systems can incorporate floating or weighted sections, high stretch for energy absorption, low stretch for depth control, and extruded ridged jackets for strum suppression. Molded eye splice terminations can be factory installed, and there are no diameter changes in transition zones, eliminating bulky hardware connections.
Shake Down Mooring Line: This technology features an outer extruded jacket with raised ridges to reduce strumming in high currents. It is more durable than hair fairing and has been extensively tested over 10 years.
Historical Context: In the 1990s, NOAA used Kevlar mooring lines, which led to significant vertical excursions of subsurface mooring floats. Switching to Vectran mooring lines with "Shake Down" extrusions reduced these excursions significantly.
Applications: The mooring systems are suitable for ocean observing systems, tsunami warnings, whale monitoring, surface current monitoring, meteorological observation, and data collection for global warming and El Niño.
