The Source Navigation Buoy is the result of a precise hydrodynamic design and testing effort to produce a buoy that will track with airgun arrays and provide a stable platform for navigation of seismic sources.
The buoys are self righting, stable in high seas, and have a wide tow speed range.
Ruggedly constructed from marine grade aluminum with closed cellular polyurethane foam fill, these buoys provide years of maintenance free operation. The steel tow bridle attachment points minimize wear, and zinc sacrificial anodes prevent galvanic corrosion. All exterior aluminum is oxide stripped, base primed, and painted with marine epoxy. Reflective material is added to the antenna mast for visibility at night. A through-hull conduit is provided to bring the electrical cable from the tow bridle to the deck. A hollow antenna mast serves to protect the antenna cable. Built-in skids allow tow aboard recovery, and provide stability on deck. Options include a strobe light, a second antenna mast, and an instrument compartment with waterproof hatch and shock mounting.
