... Abstract Fixed offshore structures are operated in shallow water depths up to 500 feet and are often subjected to huge wave loading. The huge waves destabilize the structures, which then can cause widespread damage to the local ecology, coastal towns, and the environment. Mitigating the impact...

... requirements. 4 OTC 20578 Additional influence of wave For deep water application the wave loading does not significantly impact the requirement for pliancy as the vessel motions are damped rapidly through the riser length. In ultra shallow waters, impact of wave loadings might be much more critical...

However, there is a need for a more accurate representation of the wave loading than those recommended in the standards. Therefore, model...
