For the next installment in our series of technical articles, Ryan Nicoll of DSA looks at controlling uncertainty in buoy drag coefficient when designing oceanographic moorings.
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.
