Simulated Offshore Platform Structural Monitoring System Using Real-Time Kinematics Global Positioning System

An offshore platform is a large structure with facilities to extract and process oil or
natural gas. The harsh environment due to wind, current and wave in the offshore
conditions might reduce the structural integrity of this platform especially for fixed
type platform. Thus, a good monitoring system needs to be apply at offshore
platforms for their structural integrity monitoring purposes. Global Positioning
System (GPS) Technique has been used for the purpose of structural monitoring,
however it was not done in real-time. This study proposes the real-time structural
monitoring using Real-Time-Kinematic GPS technique, albeit only in simulated
environment due to logistical constrain. Several RTK GPS configurations were
investigated to assess its accuracy for such monitoring, such as baseline distance
between rover and base station and amount of data collected. This study shows RTKGPS
technique is capable to be used as real-time structural monitoring system for
structure such as offshore platform.
