The core business of DMC is development, construction and supply of high-quality propeller nozzles. Many of the nozzle profiles are developed in-house and deliver higher efficiency for a wide range of ship types under numerous operation conditions. Their patented Optima line generates enormous thrust while significantly reducing sound and vibration. DMC has now developed an even more efficient and environmentally-friendly production method to produce the propeller nozzles with only a single weld seam on the inner side of the nozzle.
