Mooring lines are the main components in the stability of floating structures in the sea. Clump weights and submerged buoys are two types of devices designed to increase the effectiveness of mooring lines. In this article, the effect of clump weights on the motions of a semi-submersible offshore structure has been investigated considering the environmental conditions of the Persian Gulf. For this purpose, the restoring force of the mooring line in calm water conditions, the motions of the floating structure and the top tension of one of its mooring lines in an irregular wave with a return period of 100 years have been investigated. In general, adding clump weights will reduce the movements of the floating structure and increase the tension of the moorings. These two different effects show that the addition of clump weights needs further investigation.
