“…Each partitioned wave system is respectively represented by significant wave height, zerocrossing period and mean wave direction. More information on wind-driven wave models and their application to fatigue assessment can be found in Zou and Kaminski (2016) [5].…”

“…Most studies concentrated on the annual or seasonal variability of sea states, sea level rising and extreme sea states. However, the fatigue assessment requires wave scatter diagrams including the probability of occurrence of all short-term sea states [5], and the coexistence of wind waves and swells should also be considered [6]. In addition, the climate trend in the past is not necessarily representative of the climate trend in the future.…”

“…The most widely used wind-driven wave models are Ocean Wave Model (WAM) [10], Simulating WAves Nearshore model (SWAN) [11], and WaveWatch-III model [12]. The application of these models has been demonstrated on various research fields [5,13].…”

Fatigue damage is a cumulative process. The fatigue design of offshore structures requires long term wave data to calculate fatigue damage. However, the climate change may affect the long-term wave statistics and consequently affect the cumulative fatigue damage. This paper aims to project the trend of annual fatigue damage of offshore floating structures and to detect the climate change impact on the future fatigue damage by coupling a conventional fatigue design method with climate and wave models. Firstly, climate scenarios are selected to project the global radiative forcing level over decadal or century time scales. Secondly, climate models are used to simulate global or regional atmosphere circulations and to obtain the wind field data. Thirdly, wave conditions are simulated by coupling wind driven wave models to climate models. Fourthly, stress analysis and fatigue assessments are conducted to project the annual fatigue damage. At last, control simulations are carried out in order to identify the range of natural variability and to detect the human-induced change. A case study is presented for a Floating Production Storage and Offloading (FPSO) unit operating in the Sable field offshore South Africa. The results indicate that, in the Sable field, the significant wave height is considerably influenced by the human-induced climate change. However, when detecting its effect on the annual fatigue damage, this change induced by human activities is still partially masked by the dominant natural variability. In addition, both the significant wave height and the annual fatigue damage increase over century time-scales.

Structural geometry and stochastic loads such as swell and wind seas can typically induce multiaxial stress states in welded details of marine structures. It is known that such complex time varying stress states determine the fatigue resistance of welded steel joints. Therefore, it is of importance to account for them in fatigue lifetime estimation. Over the past few decades a wide variety of design guidelines and methods have been developed for multiaxial fatigue assessment, but so far there does not exist a general hypothesis applicable to all possible load cases. This study provides an overview of the current state-ofthe-art in academia and engineering practice in terms of multiaxial fatigue assessment, and is focusing on the application to welded joints in marine structures. The progress of different approaches and methods is elaborated and commented upon, taking their hypothesis and (physical) basis into consideration. The insights that are provided in this paper form a valuable foundation for future investigations and emphasize the necessity of experimental proofs and model validation.

“…Consequently, NORA10 can be recommended to be used for wave design criteria at NCS, while NoNoCur must be further developed and used with caution. Zou and Kaminski (2016) looked at the applicability of WW-III to fatigue assessment of offshore floating structures. The Bluewaters Floating Production, Storage and Offloading (FPSO) installation which has been turretmoored at the Sable field about 150 km southwest of South Africa for half a decade was used as a specific case study.…”

Following the 14th International Workshop on Wave Hindcasting and Forecasting and 5th Coastal Hazards Symposium in November 2014 in Key West, Florida, a topical collection has appeared in recent issues of Ocean Dynamics. Here, we give a brief overview of the 16 papers published in this topical collection as well as an overview of the widening scope of the conference in recent years. A general trend in the field has been towards closer integration between the wave and ocean modelling communities. This is also seen in this topical collection, with several papers exploring the interaction between surface waves and mixed layer dynamics and sea ice.
