Abstract

Ship dynamics is the movement that the ship responds to. With the dynamics of the ship, the ship also has stability. All buildings on the sea, including barges, also have stability calculations. Barge is a ship with a flat hull that has a function to transport cargo, and is pulled or pushed by tugboats. In addition to carrying cargo, barges also have a big role in the offshore world, such as carrying jackets from the fabrication site to the installation site. After reaching the installation site, the jacket will be launched into the water with the barge in a trim position so that the jacket can slide by itself or be pulled by a winch. The launching process is divided into 3 processes, namely jacket slides, jacket tipping, and jacket separates. This study aims to determine the stability conditions and trim changes in the launching process. Analysis of the stability of the barge in the launching process was carried out using the Maxsurf Stability Adv software. By previously making modeling of the launch barge with the help of Maxsurf Modeller Adv software and modeling Jacket using SACS 12.0 software. The research is carried out continuously by entering the results of the analysis in the previous stage into the analytical data to be analyzed. The results showed that in each launching condition the trim height on the launch barge increased, starting at the initial condition where the launch barge in trim condition was as high as 1,287 m or 0.4° and in the jacket tipping condition the trim condition increased to 10,372 m or 3°. In addition to getting the results of trim changes, the analysis also produces a GZ Graph, which according to the standard Noble Denton 0028 rule, that the peak of the GZ Graph is not below 20°. From 4 times of analysis experiment only 1 initial condition met the standard of launch rules.
