.... The planning prior to the offshore operations does, therefore, require accurate weather forecasting. The weather conditions may be of particular concern for operations in Arctic waters. During the season when polar low pressures can be expected in the Arctic, reliable weather forecasts exceeding one day may...

... ABSTRACT Nowadays, the problem of short- and long-term forecasts in the Russian Arctic becomes important for global logistics and engineering. Here, we present our first findings on the application of machine learning (ML) methods to oceanographic data. The Barents Sea is the region of our...

... ABSTRACT Arctic shipping along the Northern Sea Route (NSR) relies on reliable and precise sea ice concentration (SIC) information. However, the SIC forecast used to assist NSR shipping is often inaccurate. This study proposes a VAE based Non-Autoregressive Transformer model for the long-term...

Research Methods and Steps The tidal elevation is an important parameter in the design of coastal...

... Abstract This paper presents a novel initiative for reliable high–resolution forecasts on prevailing sea states at 50 important ports worldwide (Accu-Waves; http://accuwaves.eu/) . Its goal is to support safe navigation, unhampered vessel approaching to busy harbored areas, and secure ship...

... for their significance in globalization. However, forecasting WLFs of artificial/non–artificial waterways have tremendous economic benefits for locals. Forecasting WLFs can be seen as a time series problem. Artificial neural networks (ANNs) have shown promises of time series forecast and are well–documented. This study...

... Abstract An iceberg drift model was developed for offshore oil and gas operations. Increasing forecasting accuracy is critical for making appropriate downtime decisions. Three sources of ocean current data were used to run test simulations of the model: estimated from observed iceberg drift...

... ABSTRACT In the present study, a 168 hrs-forecast wave model is developed to predict significant wave heights at four stations, Japan, using the Group Method of Data Handling (GMDH). The GMDH is one of machine learning (like artificial neural network) and has an advantage of the convenience...

... ABSTRACT The extended lift operation to deliver the Wellbay module (M5) combined with the Flare Tower (M8) from the Miller Platform in the North Sea to the shore using the Semi-Submersible Crane Vessel S7000 was sensitive to the wave environment. Weather and response forecasts were used...

... ABSTRACT The influence of the accuracy of the weather forecast on the availability and production losses for a given maintenance policy are investigated in this paper. This is done by varying the look ahead time, with accurate weather forecast, of a simulation model. The results show...

... ABSTRACT The article briefly presents a novel methodology of weather window estimation for offshore operations and mainly focuses on effects of met-ocean condition forecasting uncertainties on weather window predictions when using the proposed methodology. It is demonstrated that the proposed...

Furthermore, a Kalman filter and autoregressive model were used to estimate and forecast the wave exciting force and predict the future dynamics of the WEC. The WEC's power-take-off time-averaged power and structural loads...

... models are also applied to the initial nonstationary series without making any decomposition. The performance of both forecasting procedures is assessed by means of well-known error measures. It should be noted that FIS/ANFIS models are coupled for the first time with a nonstationary time series...
