Norwegian chemical tanker operator Odfjell has reported a 20％ improvement in the efficiency of one of its Poland class tankers following the fitting of a MAN Kappel propeller and shaft improvements. Vice president of technology management at Odfjell, Knut Erik Fredriksen, told The Naval Architect that tank tests had shown that the propeller design could produce 20-50％ efficiency improvements. However, even though the tank tests showed significant savings the actual efficiencies achieved were still "amazing for us", explained Fredriksen.
