Approximately 300 oil platforms in Malaysia, especially fixed offshore platform are
approaching their service life span. Even though Malaysian waters are calm compared
to another region, an investigation needs to be done in order to avoid weak
decommissioning plans that can lead to failure of the program. In Malaysia it’s a new
field as not many projects related to decommissioning has been executed. Effect of
current under different angles on the structural member of the partial removal jacket
platform was studied. The particular interest is to investigate the structural
performance and vibration due to horizontal current forces. Offshore Structural
Analysis and Design Software (SACS) is being used as medium to simulate the
interaction between ocean current with the structural member of the jacket platform.
It is expected that the result of the hydrodynamic forces acted on the jacket platform
will determine the stress and dynamic response of the fixed platform with the
consideration of the current forces under different angles.
