Abstract

The initial stability of Semi-Submersible vessels, associated with transportation safety, can vary significantly during Floating Onload. There are some accidents happening in the past during operations of floating onload, and it highlights the requirement of analyzing the stability during this period in more detail. Based on ship statics, this paper took theoretical analysis of the semi-submersible vessel’s hydrostatic data. It reveals that the number of GM can drop to the minimum, even to 0 or negative value, when the main deck submerged completely if the trim is 0. However, when the semi-submersible vessel is floating onload in other floating conditions, the minimum GM can be improved and the rate of drop of GM can be decreased. Finally, this paper suggests that the semi-submersible vessel can improve the initial stability through altering its floating condition to trim by bow when the main deck begins to submerge.
