CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
It maintains constant tension on cables or lines in passive heave compensation systems, compensating for vertical vessel motion without active power input.
It uses mechanical or hydraulic accumulators, springs, or counterweights to absorb and release energy as the vessel heaves, adjusting cable payout and retrieval to maintain tension.
