If you want a specific excerpt (e.g., the formula for local crushing pressure, a table of typical ice strengths, or the probabilistic load derivation), tell me which piece and I’ll provide a concise, focused extract.

The DNV-RP-F118 standard, published by Det Norske Veritas (DNV), is a widely recognized and respected guideline for geotechnical design and analysis in the offshore industry. This document provides a framework for assessing the stability and integrity of offshore structures, ensuring their safe and reliable operation in various environmental conditions. dnv-rp-f118

| Limit State | Description | Check example | |-------------|-------------|----------------| | (Ultimate) | Maximum load capacity under extreme environmental conditions (e.g., 100-year storm). | Yield or buckling of steel riser under tension + pressure + bending. | | FLS (Fatigue) | Accumulated damage from cyclic loads (waves, vessel motion, vortex-induced vibration). | 20-year fatigue life with safety factor of 3 (or 10 for inaccessible, non-repairable locations). | | ALS (Accidental) | Survivability after damage (e.g., dropped object, collision, fire). | Residual strength of dented riser. | | SLS (Serviceability) | Functionality under normal operation. | Excessive deflection causing interference with other risers or mooring lines. | If you want a specific excerpt (e
