Reducing Heave Response Amplitude Operator of A Semi-submersiblePlatform Attached by Styrene Butadiene Rubber Composites

This study investigates the effectiveness of attaching styrene butadiene rubber (SBR) layers to thebottom of a semi-submersible platform's pontoons in reducing heave motion response. The heaveresponse amplitude operator (RAO) was computed analytically using the Eigenfunction ExpansionMethod. After that, the generated equations were compared to experimental data that was availablefor a platform without SBR, and they showed good agreement. Subsequently, the heave RAO valuesof the modified semi-submersible with SBR were calculated. The results revealed that the propertiesof SBR can eliminate the risk of resonance phenomena in semi-submersible platforms.
