Part 2 of Dr. Peter Spain’s article on the development of ADCP technology and the use of syntactic foam buoyancy in subsea moorings.
Hydro-float® Mooring Buoys
DeepWater Buoyancy’s spherical subsurface mooring buoys provide exceptionally reliable buoyancy for a variety of oceanographic, commercial, military and offshore applications. Made from DeepTec® syntactic foam, Hydro-float® Mooring Buoys (HMBs) offer a low-maintenance and cost-effective solution for subsurface moorings and other offshore applications.
Because of their solid construction, these buoys may be cast with through holes and instrumentation pockets on any axis without compromising reliability. Clamps and mounting hardware can be added for any user-supplied instrumentation. 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, elliptical buoys or streamlined designs, like our StableMoor®, are also offered, further reducing drag on moorings in high current areas. HMB’s can be fitted with integral tail fins providing additional stability while minimizing stress on rigging.

Trawl-Resistant Bottom Mounts
These TRBMs may be deployed by free-fall, or by a diver or ROV. They have a double axis gimbal inside a buoyant recovery pod, and are designed to permit retrieval of all mounted instruments. An optional Spectra line pack can be provided for recovery of the base for turnaround deployments. Our TRBMs are available in depths of over 500 meters. We also offer disposable concrete bases.

HardBall® Floats
HardBall® Floats provide distributed buoyancy for cable laying, offshore, and oceanographic applications. They are available in a range of sizes and depth ratings. Unlike glass balls or hollow plastic floats, HardBall® Floats cannot leak or implode. Only the highest strength, epoxy-based DeepTec® syntactic foams are used to form the core — no macrospheres or other high risk materials.

New ProductMooring Line Cable Fairing
Under certain flow conditions, taut mooring lines can vibrate or “strum”. The strumming is caused by vortices that result from the water passing over the line diameter. Strumming not only creates cable fatigue, it can have a detrimental effect on instruments in the mooring string. Our cable fairings reduce strumming by eliminating this vortex action. The result is a reduction in both strumming and drag.
