<p>A flow line 14 has weight elements 42 connected thereto for making the combination negatively buoyant. At rates of speed above a threshold level, the weight means creates an upward lifting force as the flow line is towed through a body of water 6. The flow line also has depressor elements 44 connected thereto to apply a downward force to the flow line to offset the lifting force created by the weight elements. The depressor elements are located adjacent the weight elements to prevent an oscillating or "snaking" motion from being imparted to the flow line as it is towed through the body of water above the threshold level.</p> |
