Response-Based Forecasting of Vessel Motion Shifts to Data-Driven Methods

This paper reviews the motivation and development of response-based forecasting from the perspective of the authors, reviewing examples and processes that have served as validation and led to modeling refinement.

The conventional approach used to assess the operability of floating facilities typically has been based on wave height rather than wave-induced responses. During the past decade, this paradigm has been challenged through the development and provision of response-based forecasting. The availability of reliable measured motion data from vessels has enabled probabilistic rather than deterministic predictions through the application of statistical methods. The complete paper explores the motivation and development of response-based forecasting from the authors’ perspective, reviewing examples and processes that have served as validation and led to modeling refinement.

Fundamentals of Response-Based Forecasts and Sources of Error

Physics-Based Computation of Response Statistics. The theoretical framework for estimating the statistics of vessel response from wave spectra by means of linear hydrodynamic theory is well-established. Further, second-order effects such as slow drift, or contributions from winds and currents, are excluded.
