Full spade rudders with asymmetric leading edge and bulb in the wake of the propeller to further enhance flow along the rudder and reduce turbulence, will enable considerable fuel savings for the six new 7,100 TEU container vessels that Asiatic Lloyd aims to take in operation from early 2023.
Damen Marine Components (DMC) will provide one Van der Velden® Atlantic Rudder for each vessel. These rudders are known to cause minimal drag thanks to their slim design.
For these container vessels, Asymmetric Rudder Technology (ART) will be applied in the design of the leading edge of the rudder. A rudder bulb in the wake of the propeller axis further improves the hydrodynamic properties of the rudder configuration.
The Singaporean shipping arm of AL Group Asiatic Lloyd has ordered the six 7,100 TEU feeders at Dalian Shipbuilding Industry Co, the yard will deliver six vessels during 2023 to 2025.
The four identical vessels measure 255m in length, with a 42.8m beam, and a 14.5m design load draught and a design speed of 21.4 knots. Damen will provide the tailor designed rudder for each one of the vessels, measuring 61 square meter and generating 3300 Kilonewton meter of torque.
