SLOSHING IMPACT PRESSURE INDUCED ON CARGO OIL TANK WALLS OF THE MIDDLE-SIZED DOUBLE HULL TANKER

Abstract

This paper deals with the numerical analysis of sloshing problems for the middle-sized double hull tanker. The new sloshing code is based on the SOLA-SURF scheme and a simple two- dimensional sloshing code. The new code has many convenient functional tools for analysing sloshing liquid violent motions in the octagon-shaped tank fitted with deep centre girder, deep deck centre girder, deck side girder, horizontal girder etc. Numerical simulations are carried out for the cargo oil tanks of the tanker and its model tanks in order to examine the characteristics of sloshing impact pressure. Those numerical results are classified following Olsen's method, and it is confirmed that the new sloshing code is useful for estimating the sloshing impact pressure induced in the cargo oil tank.
