Abstract
Complex marine operations are moving further
from shore, into deeper waters, and harsher environments. The
operating hours of a vessel are weather dependent, and good
knowledge of the prevailing weather conditions may ensure
cost-efficient and safe operations. This paper considers the
estimation of the peak wave frequency of the on-site sea state
based on the vessel’s motion in waves. A sea state can be
described by significant wave height, peak wave frequency,
wave direction, and often wind speed and direction are added
as well. The signal-based algorithm presented in this paper is
based on Fourier transforms of the vessel response in heave,
roll and pitch. The measurements are used directly to obtain
an estimate of the peak frequency of the waves. Experimental
results from model-scale offshore ship runs at the Marine
Cybernetics Laboratory (MCLab) at NTNU demonstrate the
performance of the proposed sea state estimation algorithm.
