This type of buoyancy is preferred in a vehicle that, inherently, needs to sink in order to operate and then float for recovery. In an ROV, active buoyancy may allow for more efficient use of thrusters and preserve power, which was the motivation for Love et al. to implement the system into the Tethra submersible.

HDPE flange joints are geometrically rigid asselies, unlike the flexible HDPE pipe ring "hoop". The rigid flanged joint cannot shed stress by ring deformation. Localized HDPE pipe beam-bending at a flanged joint due to soil settlement, water buoyancy or wave action, pipe "snaking" above ground, etc, must be managed so as to isolate the flange from beam-bending strain.
