ABSTRAK

HZEB jacket wellhead tripod platform is one of the offshore structure to exploit offshore oil and gas. The Jacket which is located around ardjuna field Java Sea Indonesia has been there for 20 years and about to be modified with the adding of the conductor and deck extension. The platform structure should meet the minimum standar if API RP 2A that implies structure pushover analyze should be done and acquire minimum Reserve Strength Ratio RSR of 08 for unmanned platform to gain safe condition. Structure pile soil space frame model has been made using element till global modelling. Extreme lateral loads tide wind current should be applied to the structure on 12 direction of loads rendering. From the pushover analysing we acquire the least amount of RSR is 294 at the 120 directions of load rendering. It can be concluded that the structure of jacket wellhead tripod platforms RSR meet the minimum standar of 08 from API RP 2A WSO for unmanned platform. The result of pushover analyze in global analysing structur shows that the maximum stress value is 262 Mpa
