As an ageing platform has passed its design life of 20 to 30 years, it is crucial to identify wether it is still fit for operation based on the current environmental behaviour, particularly due to the wave impact. Hence, an analytical approach of wave spectrum analysis between the wave behaviour and offshore structural response will be conducted. The aim is to verify the stability and safety of ageing offshore platforms with the current wave behaviour based on identifying wave characteristics, developing a normalized wave energy spectral density, and analyzing the natural frequency of offshore structural response. The methodology includes data collection from structural dynamic monitoring assessments, wave spectrum development using empirical models, and evaluation of offshore platform stability. The results will provide insights into platform stability, resonance risks, and safety assessment of ageing offshore platforms in Malaysian waters. The findings will contribute to recommendations for modifications or improvements to ensure the safety and integrity of offshore platforms in the specific region.
