... for practice for designing offshore structures is estimation of extreme ice forces on structure. The calculation procedures are based on ice strength values which is proved to be the main parameter but it determination meet many obstacles. The paper presents the correlation between ice strength and dynamic...

... 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...

... responses are presented. The phenomena and results are similar to the field observations, and some features different from those of ice-induced vibrations of column structures were obtained. INTRODUCTION Ice-breaking cones, as an effective method to reduce ice force, have been designed and added to legs...
