Time-Domain Simulation of OSV Operation

Abstract

Abstract:

A simulation approach for offshore support vessel (OSV) operation is established in the Matlab/Simulink environment. The time-domain numerical results were concurrently transferred into the visualization package to accomplish the virtual operation and control. The typical gangway deployment of the case vessel "Runjiang 1" in station keeping condition was successfully simulated on this virtual platform. The complete time-domain results are valuable for safety assessment and procedure optimization.

Key words: offshore support vessel, gangway deployment, station keeping, time-domain simulation, safety assessment
