The Challenge

The assignment was to provide a communications platform for submarines, that can operate is a range of challenging hydrodynamic conditions whilst being towed. The communications buoy must be capable of receiving Very Low Frequency (VLF). The buoy has to be capable of surviving prolonged exposure to the most severe of environments.

Our Solution

The towed buoy is constructed with a rigid PVC foam core which is encapsulated within an exterior GRP skin. When deployed from its purpose designed housing on the host submersible platform, the buoy ascends under natural buoyancy. The hydrodynamic design of the buoy allows it to display underwater handling characteristics similar to that of a kite in air, and it is capable of being towed at speeds in excess of 20 knots.

The Outcome

PE Composites have manufactured a range of towed buoys and continue to maintain them as required at times of refit.
