Flotation Technologies

High Performance Subsurface Flotation

Flotation Technologies' subsurface mooring buoys provide exceptionally reliable buoyancy for a variety of oceanographic, commercial, military and offshore applications. Made from low-density Flotec™ syntactic foam or Sphere-lite™ composite foam, Hydro-Float™ Mooring Buoys (HMB) offer a low-maintenance and cost-effective solution for subsurface moorings and other offshore applications. HMBs are more versatile and reliable than conventional hollow glass or metal floats. The buoys may be cast with through holes and instrumentation pockets on any axis without compromising their strength because of their solid construction. Clamps and mounting hardware can be designed and fabricated for any user-supplied instrumentation.

A Variety of Low Drag Designs

HMBs come in many standard sizes and can be customized to meet specific needs. While spheres are used in a wide range of flow regimes, streamlined designs, like our StableMoor, are also offered further reducing drag on moorings in high current areas. Buoys can be fitted with integral tail fins providing stability, and improving the quality of the data return while minimizing stress on rigging.

Purpose Built for Hardware & Instrumentation

Buoys are offered with a full range of depth ratings up to 7000m and can be configured for instrumentation packages and specialized mooring hardware. Removable hardware assemblies are available in Type 316L stainless, galvanized steel and titanium depending on the service and load rating requirements. HMBs are manufactured to outperform and outlast conventional mooring flotation. Unlike glass or metal spheres, syntactic foam buoys will not corrode, leak or implode. They provide years of reliable service and require a minimum amount of maintenance. A variety of optional coatings are offered such as fiberglass, polyethylene and urethane elastomer, and are selected based on the demands of the application.

These are standard sizes and depth ratings. Others are available on request.
