For the next installment in our series, Dr. Peter Spain of Teledyne RD Instruments looks at the development of ADCP technology and the use of syntactic foam buoyancy in subsea moorings.
Cable Floats
Cable floats from DeepWater Buoyancy provide low-drag distributed buoyancy for a variety of offshore, commercial, military and oceanographic applications. Available with two attachment methods and sized to fit any cable, these floats are some of the most versatile buoyancy products available. They are available with depth ratings to 6000 meters.
Quick-Loc® cable floats feature a hinge and latch system for frequent deployment and recovery during ROV operations. Bolt-on style floats are designed for long term deployments such as deepwater moorings. The buoyant core of DeepTec® solid syntactic foam is protected from impact and abrasion by a high impact ABS or polyethylene outer shell. Type 316L stainless steel, titanium or composite hardware can be specified, based on the requirement.
HD series cable floats are ideal for large diameter armored cables and control umbilicals. Designed to handle stresses caused by cable bending, they provide maximum performance and durability for a variety of applications. Polyurethane elastomer inserts provide maximum grip and allow the cable to flex to its minimum bend radius without damaging the cable or flotation.

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.

Instrument Collars
Designed for long term submergence, our instrument collars provide years of reliable service and stand up to rough handling during operations. Each yields the buoyant force needed for a rapid ascent and positive recovery without impairing the performance of the instrument. From shallow water surveys to ultra deepwater positioning, you can count on these collars to help ensure overall success in the field.

ROVits®
Designed similarly to “tether balls,” ROVits® are our answer to the request for multi-purpose small floats. ROVits® provide buoyancy to make manipulator and ROV tasks easier, especially where hardware like lift eyes, pins, and handles are involved. ROVits’® rugged design and 3000m depth rating make them the most versatile tool in your support van.
