Abstract

The environmental load factor in the ISO 19902 standards is derived based on conditions in the
Gulf of Mexico, which are more extreme than conditions in Indonesia. This study is a preliminary investigation
of the environmental load factors appropriate for the Java Sea, as this is a region in Indonesia where many
platform structures are already in operation. Evaluation of an environmental load factor for Indonesia is carried
out by performing reliability analyses using Monte Carlo simulations, in which the failure performance is
determined by the first yield stress condition in the critical member of two fixed platform structures. From the
results, an appropriate environmental load factor of 1.16 is proposed for the Java Sea, which is smaller than
the value given in the ISO 20002 Standard for the Gulf of Mexico. More comprehensive environmental load
factor research for other Indonesian regions should be done to complement this result.
