... 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...

... ABSTRACT Assessment of the expected stand-by in offshore operations is performed by analysing the metocean conditions of the area and comparing them with the operative limits defined by static and dynamic installation analyses. Generally, seastate hindcast time series, nowadays available...
