Wave-in-Deck Force on Fixed Jacket Platforms by Silhoutte Method and Detailed Component Method

Wave-in-deck creates extra forces to the platform by increasing its moment arm which cause instability in terms of overturning. Fixed offshore platforms are generally not intended to withstand the substantial forces produced by wave-in-deck loads. Nonetheless, the requirement to accurately predict t...
