Abstract: Full-scale tests of ice-structure interaction were conducted on three multileg jacket platforms in Bohai Sea. Two of them were installed with ice-breaking cones on each of their four legs to reduce ice force and mitigate ...

Abstract: Steady amplitude vibration on cylinder structures caused by dynamic ice loading has been observed during the measurements on prototype structures. Further analysis indicates that it belongs to self-excited vibration, in ...

Abstract: In China, the oil and natural gas resources in Bohai Bay are mainly marginal oil fields, which freeze in the winter. It is necessary to build both ice-resistant and economical offshore ...

Abstract: A vertical riser pipe is often mounted on the leg of an offshore platform to transport oil and gas. However, severe ice-induced vibrations and low-cycle fatigue damage of welded joints have been observed on the outside ...

Abstract: This paper presents a model of dynamic ice forces on vertical offshore structures. The model concerns a loading scenario where a competent ice sheet is drifting and crushing against the ...

Abstract: Jackup structures that have cylindrical legs with gear teeth are widely used in shallow waters. Currently, there is a growing demand for the design of ice-resistant jackup platforms in ice-prone cold regions. Due to the ...

Abstract: Ice-structure interaction plays a central part in determining ice loads and ice-induced vibrations. This is a controversial research issue, and many factors make the problem more complicated. The ...
