Abstract
- Ice force predictions using the ISO 19906 Arctic offshore structures standard and three national standards have been compared for structures offshore Sakhalin. A multi-leg structure with leg diameters 18 and 24 m subjected to several design ice conditions, level ice 1.2 m, rafted ice 3.5 m and a first year ridge keel 21 m deep was evaluated. ISO 19906 is the most complete and transparent standard in providing guidance. It incorporates guidance on ice strength from the Russian standard, and ice thickness and geometry effects from the Canadian standard. Further guidance is still needed for multi-leg structures.<br />The Tenth (2012) ISOPE Pacific/Asia Offshore Mechanics Symposium, October 3-5, 2012, Vladivostok, Russia<br />Series: Proceedings of the Pacific/Asia Offshore Mechanics Symposiums(ISOPE PACOMS)
