摘要

Shallow water infrastructure needs to support increased activity on the shores of Semarang. This study chooses several pontoons because of their good stability, rolling motion, and more expansive space. A coupled simulation method consisting of hydrodynamic and structural calculations has been used to evaluate a catamaran pontoon’s motion and structural integrity. Four different space sizes are set for the pontoon system: 5 m, 5.5 m, 6 m, and 6.5 m. The frequency domain shows that the pontoon space affects the RAO in wave periods ranging from 3 s to 5 s. At wave periods of 3 s, 4 s, and 5 s, the pontoon space significantly affects the maximum motion and chain tension parameter values, which are evaluated via time domain simulation. The critical stress of the pontoon is shown at a wave period of 5 s for 5 m and 5.5 m of pontoon space, which shows that the stress can reach 248 MPa.
