... ABSTRACT Level ice is one of the main ice types encountered by the offshore structures operated in ice zone, while vertical and inclined structures are the commonest configurations, so it is of great significance for reinforced ice-resistant design and safety evaluation to study the ice...

..., which has the characteristic of sudden failure, is one of the most threatening issue for offshore structures. For a long time in the past, offshore structures were mainly built based on traditional steel structures like the use of shaped steel or hollow steel tube, and existing literatures provide...

... the United States and Cuba; called the Gulf of Mexico; which remains an ocean basin given by the continental geography. However; any offshore structure requires specific adjustments both for its construction and for its operations; and thus; avoid damage that may be caused by wave forces that intervene...

.... The metrology mast, is located six kilometers offshore from Changhua Wang-Gong Fishing Port. The information provided by the mast will have a significant bearing on the design of offshore structures in the future, such as offshore wind turbines. In the present study, we analyze data obtained from the mast...

... ABSTRACT Ice-Mas is a simulator used for design of offshore structures interacting with ice combining a variety of models and approaches. It was initiated by TechnipFMC with a joint-cooperation with Cervval and Bureau Veritas. This paper present overall functionalities of Ice-Mas...

... that the characteristics of the impact forces are closely related to the motion responses of the DTV and the semi-submersible platform. Discussions were made on the effects of wave headings, load transfers on the impact forces of LMUs and Jack system. INTRODUCTION As the size of the offshore structures has increased...

...-water loads on the pillar. INTRODUCTION Under extreme wave conditions, floating offshore structure will exhibit large motion responses and be exposed to various wave impact loads at the same time. In particular, when the relative wave height is higher than the freeboard of the structures, green...

Measures could mitigate the wave loads on offshore structures is of great significance in practical engineering. It is well known that strong...

... ABSTRACT Geotechnical considerations are important in identifying the conditions leading to instability of seabed-offshore-structures under waves. It is necessary to model such soil behavior via theoretical frameworks. This paper summarizes the fundamentals of constitutive modeling of cyclic...

... ABSTRACT Periods of growth in the offshore industry have involved considerable interest in and investigation of the survivability of offshore structures against various hazards. The potential for changes in the frequency and intensity of severe weather events due to climate change...

.... INTRODUCTION As the offshore exploitation is going further into deep sea, offshore structures such as drillship are to be used in harsh marine environment, including strong wind, current and waves. Especially for wind, it can make great effect on DP system of offshore structures which is designed to keep them...
