THE W-11-4A PLATFORM COMPREHENSIVE STRENGTH MONITORING-SYSTEM

A comprehensive strength monitoring system used on a fixed jacket plat form is presented in this paper. The long-term monitoring of W-11-4A p latform achieved. Structural responses (strain and acceleration) at se lected locations, as well as associated environmental parameters, have been obtained. The emphasis of the paper is placed on the system desi gn, and the instrumentation and operation methodology employed in the monitoring of the structural responses. The performance of the system and the characteristic results obtained during its 13-month operation are also summarized.
