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.
MiniMod™ Small Modular Buoy
Our modular buoys are the most versatile approach for offshore applications. They are offered in a variety of standard sizes with buoyancy as great as 2 metric tons and depth ratings to 6000 meters. For installation of pipeline sleds, jumpers, or suspended moorings, this multi-purpose product offers a straightforward way to meet buoyancy requirements.
Our MiniMod™ small modular buoys are designed for lighter applications. Still rated to depths as great as 6000 meters, the standard 7-module buoy can provide up to 325 kg of buoyancy. Made from high-strength DeepTec® solid syntactic foam that is finished with an abrasion-resistant, polyurethane elastomer coating, these buoys can stand up to rough handling on-deck and in the water.
The syntactic foam modules are held together and handled by use of synthetic straps, as opposed to metal hardware. These straps have numerous benefits including corrosion resistance, ease of handling, and no loss of buoyancy. Modules interlock for added strength and can easily be added or removed for your application.
With rugged construction and the world’s most reliable, field-proven syntactic foams, these truly modular buoys provide offshore users with years of trouble-free service.
