ASSESSMENT OF SLOSHING LOADS FOR TANKERS

This paper presents a new procedure to assess sloshing loads for tankers. It is applied to a sample tanker. Starting with computed ship motions and fluid motions inside partially filled tanks, critical fill levels were identified. Simulation of fluid flow was performed with a finite volume method for each critical fill level. Two- and three-dimensional flow computations were employed to predict pressure loads for panel sized patches of tank walls. Time traces of pressure were analyzed and resulting maximum loads were compared for all critical fill levels to determine overall maximum loads. Results generally agreed favorably with current rule based values.
