... Abstract Different kinds of offshore structures are designed and built to resist the scenarios of the arctic environment. This paper focuses on different ice load scenarios and the challenges for fixed offshore structures. Model test methods will be presented to assess the suitability...

... induced vibrations. However, a fatigue capacity may be reduced due to geometrical discontinuity with the increase of inclination angle. This was shown in the design analysis. subsea system conical structure wellhead platform offshore structure platform ice resistant structure optimisation...

... Abstract Ice accretion on vessels and offshore structures is a serious operational hazard. Heavy ice accumulation on vessel's deck can influence the stability and potentially capsize smaller vessels. It also creates unsafe operational conditions on vessel and offshore platform decks. Accurate...

... Abstract Existing standards and codes do not comprehensively address and provide all necessary guidance and requirements for the design of Arctic offshore structures. Reliably assessing ice loads on offshore structures remains a challenge for industry, especially as "new" Arctic platform...

... Abstract Exploitation of the Arctic's resources requires the mastery of the risks caused by extreme ice conditions. The design of offshore structures subjected to extreme ice conditions is a challenge for engineers since there are very few advanced design tools available on the market...

... Abstract Wave driven iceberg and bergy bits’ impact load with an offshore structure is an important design concern. Hydrodynamic interaction between iceberg / bergy bit and an offshore structure in close proximity is an important factor that governs the impact load. Recently, a set...

... Abstract There is a wide range of offshore structures which may be constructed byeither steel or concrete materials to be used in the arctic region, such assteel tower platforms, caisson-retained islands, shallow-water gravity-basecaisson, jack-up structures, bottom-founded deep-water...

... Abstract The new ISO 19906 Arctic Offshore Structures standard contains provisions relating to a number of different types of offshore oil and gas structures in the Arctic and in other cold regions. Its provisions supplement those of ISO 19902 (steel offshore structures), ISO 19903 (concrete...
