“…In addition, the complex geometry of a ship hull can lead to difficulties in correctly modelling the physics of the motion dynamics of a ship in waves; especially considering higher and steeper waves. What is more, sometimes the hull geometry is not available to the ship operator, in which case so-called closed-form expressions 51 , 52 can be used as an approximate alternative for the transfer functions. Nevertheless, transfer functions presumably yield a qualitatively correct picture of a ship’s response in waves.…”

Optimisation of energy efficiency and operational performance as well as assessment of safety levels and emissions of marine operations require detailed information about the acting wave system. It is possible—with an analogy to classical wave buoys—to estimate the directional wave spectrum by processing sensor measurements of wave-induced responses (e.g., motions and structural responses) from a ship. Compared to other sources of wave data (e.g., buoys, satellites, third-generation wave models), estimation concepts using the ship itself as a buoy provide the wave spectrum at the exact spatio-temporal point, potentially increasing accuracy and with minimal associated cost. This paper gives an overview of the technology, discusses associated uncertainties, and highlights new developments made for estimating waves via measured ship responses.
