Decommissioning of platform activities getting increase due to unproductive fields and
unstable oil prices. One of the decommissioning methods used by Oil and Gas
Company is by converting the platform into artificial reef through Rigs-to-Reef (RTR)
program. However, the sediment scour around jacket platform is one of the problem
to be concerned because it will result in RTR program failure. This program creates
shelter and increased the fish production and also to understand the functioning of
current RTR program on analyzing the successes and failures. In this study, the seabed
profile around the jacket platform was investigated using Computational Fluid Dynamic
(CFD). The simulation of the seabed scour depth around jacket platform is compared
with previous experimental results for validation purposes. The result showed the flow
velocity become decrease when the flow was obstructed in front of the jacket platform.
The flow on the other sides of jacket structure accelerate lead to high bed shear stress
that induces scour around the structure.
