General The design wave calculation by the short term stochastic method is provided in the ABS Rules for Building and Classing Mobile Offshore Drilling Units (MODU Rules). The ABS Rules for Building and Classing Floating Production Installations (FPI Rules) require the installation??s hull strength and fatigue assessment in the site-specific environmental conditions@ considering both 100-year return period environmental events and wave scatter diagram data of wave height/period joint occurrence distributions. As a supplement to select the design wave from the site specific environmental conditions@ these Guidance Notes provide the detailed procedures to determine the design wave by the long term stochastic method for non-ship type offshore structures.
