Abstract

Long-lasting high stability is of primary importance to successful COM combustion. Much has been done in the way of research on stability of COM in the still storage, and the mechanism of COM still stability is almost completely known. On the other hand, the knowledge about the dynamic stability of COM, such as COM stability while being transported aboard the COM carrier at sea, is still limited at the moment.<BR>The motion of COM aboard the COM carrier and how COM would settle under dynamic ship motions were tested by simulation using different sized model cargo holds. In the tests the mechanism of COM dynamic stability was analysed with the effect of the size of each model cargo hold in mind. The tests showed that the ship rolling motion would have undesirable effect of promoting the settling of coal content of COM in the cargo hold.
