New Design of 2000 TEU Feeder
Design bureau Knud E. Hansen A/S, Denmark together with ABB, recently unveiled a new design of 2000 TEU Container Feeder Vessel. A high container capacity together with an efficient propulsion system claims to offer a 15 to 25 per cent better fuel economy per TEU than typical feeder vessels of similar size.

A midship position of the deckhouse provides better vision from the bridge than an aft location
permitting approximately 15 per cent more containers to be carried on deck. The main dimensions are LOA 564 ft (172 m) and beam of 98 ft (30 m). Used in Bangkok-max configuration the draft is 27 ft (8.2 m) with a deadweight of 18,300 t: fully loaded to a 28,400 t maximum, the draft increases to 34.5 ft (10.5 m).
The unusual propulsion system comprises a main shaft driven propeller providing 65 per cent of thrust with an electrically driven counter rotating ABB Azipod thruster, fitted behind the directly the main propeller. The Azipod can turn through 360 degrees, giving good manoeuverability and independence from tug assistance in port under most circumstances. A further benefit of this system is that the propeller diameter is reduced, removing the need for ballast water to submerge the propeller in lightly loaded conditions.
The main engine drives a shaft generator which at 18 kn produces sufficient power for the Azipod, the hotel load and the reefer containers. Additional power from three auxiliary gensets totaling 8000 kW is available for higher speeds up to 21 kn, or if a larger number of reefer containers are on board. Running on the Azipod and gensets only, a speed of up to 13 kn can be maintained providing a fully redundant propulsion system. An ABB Onboard DC grid system manages operation of the engines, ensuring optimal loading at any cruising speed between 2 and 21 knots.
