Title: Experimental Study on the Maneuverability For a Wide Beam New Suezmax Class Tanker
Abstract: This chapter investigates some comparative model tests with conventional rudder and high lift rudder. In the course of designing and building a wide beam single screw Suezmax tanker with unfavorable main particulars in sense of ship's maneuverability, especially course keeping ability, various kinds of model test techniques such as planar motion mechanism (PMM) test and free running test from different model basins including Hyundai Maritime Research Institute (HMRI) were studied to estimate and improve its maneuvering performance, and their model test results were compared. Although a special type of high lift rudder with comparatively large area was integrated during the design, it is found that carefully developed hull form, especially in the region of stern profile and section shape, seems to be more important to enhance ship's maneuverability. Through the various model tests, it can be stated that even such a very exceptional dimensioned single screw monohull is able to maintain sufficient maneuverability by careful design and integration of the hull form and rudder, which is verified at sea trial. Through various maneuvering studies on the hull form and rudder design and also through a series of model tests, the maneuverability of the vessel is cleared to be sufficiently stable and within the IMO criteria. Excessive rudder area in case of using the high lift rudder is not effective and shows only marginal improvement of maneuverability of ship. It is important that the optimum size and shape of the rudder to satisfy both of the powering performance and maneuverability be appropriately selected in the design stage.
