Abstract: Slow steaming and regulatory drive toward more energy efficient ships have raised a problem of ensuring sufficient maneuverability of ships under adverse weather conditions when installed power is reduced. This paper ...

Abstract: The paper describes a numerical approach to predict required added power for propulsion in waves. Such predictions are important to address fuel consumption in seaway and define suitable operating point and sea margin, as ...

Abstract: For a series of five containerships of differing capacities (707, 3400, 5300, 14,000, and 18,000 TEU), systematic computations were performed to estimate the tow force required in an emergency. Timeaverage ship positions ...

Abstract: A Rankine source method is extended and applied to ship–ship interaction problems. The method covers the nonlinear steady flow and linear seakeeping in the frequency domain. The nonlinear steady flow solution accounts ...

Abstract: A Rankine source method is applied to predict linear and weakly nonlinear sectional loads of a modern container ship. The method uses solution in the frequency domain, linearized with respect to wave amplitude about the ...

Abstract: Horizontal sectional loads (horizontal shear force and horizontal bending moment) and torsional moment are more difficult to predict with potential flow methods than vertical loads, especially in sternquartering waves. ...

Abstract: A new Rankine panel method and an extended ReynoldsAveraged Navier–Stokes (RANS) solver were employed to predict added resistance in head waves at different Froude numbers of a Wigley hull, a large tanker, and a modern ...
