![]() ![]() #Feeder vessel meaning full#“The problem being that, when you come to carrying a full load you require a wider water line for additional stability. “In this situation, you don’t want anything more than sufficient stability and so a narrow hull is preferable,” says Mr. What’s more, the vessel can be built with HFO tanks and easily retrofitted for LNG the day the infrastructure for LNG is sufficiently developed if a dual-fuel engine is installed in the first place.” Here, we have a square block below the deckhouse, in which we can either have HFO tanks or LNG tanks. This arrangement has additional benefits: “This prepares the vessel for LNG and dual-fuel propulsion – attributes that are becoming increasingly sought after. The added number of slots can be utilized in real-life loading conditions because the vessel is wider and has a higher stability than most feeder vessels of this size. Unlike most feeder vessels, the deckhouse of this vessel is positioned slightly forward of amidships to maximize the number of container slots on deck considering the IMO requirements to the line of vision from the bridge. “With the large propeller we get a propulsion efficiency which is not that far from the efficiency of a counter-rotating solution, but for a much lower cost.” With draught not being a primary consideration, this design sees the feeder vessel fitted out with a larger diameter, slower-turning propeller. 7.4 m and further, the counter-rotating propeller will recover some of the swirl energy produced by the main propeller, which increases the overall efficiency.”Ī second design foresees a vessel which does not require such a shallow draught and which will have a 3,800 TEU capacity. The total propeller disk area of the two propellers corresponds to the area of a single propeller with a diameter of approx. HANSEN, explains: “The dual arrangement makes up for the relative small diameter of the propellers. Jesper Kanstrup, Senior Naval Architect at KNUD E. ![]() HANSEN’s designers presented a special propeller arrangement employing a directly driven main propeller with a diameter of 5.8 m and a counter-rotating Azipod with a 4.7 m propeller. To cater for this without a loss of power, KNUD E. To fulfil this, the vessel requires a relatively small diameter propeller. Navigating such harbours requires a vessel to have a shallow draught – in the case of Bangkok, not more than 8.2 metres. #Feeder vessel meaning series#The first in the series of three designs relates to a 2000 TEU vessel that was conceived of to specialise in calling at small, narrow, up-river ports, for example the Port of Bangkok, Thailand. Each of the designs presents a series of innovations as part of a solution tailored to specific requirements. ![]() HANSEN has recently been developing a number of pioneering container feeder vessel designs.
