The removal of offshore oil and gas platforms from the seafloor at the end of
production is required by the law. One of the ways is to turn the platform into an
artificial reef through rig-to-reef (RTR) program. The artificial reef provides favorable
habitat conditions for fish or coral by altering the flow field. Since the current speed
may vary from one location to the other, the flow field created by the submerged
jacket platform may not be a favorable condition for the fish habitat. Therefore, we
adopted CFD method to analyze the flow profile produce by the artificial reef in several
current speeds and determine the stress on the structure and flow characteristics that
influenced by the flow field. To conclude, the simulation results should benefit ocean
engineers and marine biologists by unveiling various flow patterns and stress in
different part of the structure due to difference in current speed.
