SUBS – Model A2 Coastal ADCP/ADP Buoy

Streamlined Underwater Buoyancy System

  • Improves data by significantly enhancing instrument stability
  • Virtually eliminates instrument movement due to vortex shedding behind spheres
  • Light weight – easy to handle
  • Smaller frontal area and decreased drag coefficient – less mooring inclination and excursion
  • Ideal for ADP’s, ADCP’s, single point current meters, optical and acoustic instruments

  • Mounting ADCP’s or other instrumentation in a streamlined buoyancy package reduces the variability caused by mooring movement typical of spherical buoyancy.
  • Few instruments have the capability of segregating mooring movement from actual data.
  • Reducing mooring movement is a significant criteria in acoustic mooring design.
  • Reduced frontal area and drag coefficient allow a smaller and lighter mooring.
  • Reducing mooring movement is a prime design criteria of optic moorings.

BENEFITS

  • Unmatched mooring stability provides the best in instrument platforms.
  • Virtually eliminates vortex shedding effects which are inherent with spherical floatation.
  • Reduces the potential for the measurement errors associated with mooring movement.
  • Substantially reduces mooring excursions and inclinations.
  • Significant improvement to depth keeping characteristics.
  • Self-compensating for mooring inclination and flow direction.
  • Reduced buoyancy requirement due to lower mooring frontal area.
  • Supplied complete with buoyancy or purchasers can utilise their existing VinyFloats.
