1. A vessel environmental condition assessment method, comprising:
providing a vessel environment condition assessment system comprising a processor and a motion measurement unit on board a vessel configured to sense the vessel's motion, wherein the motion measurement unit is configured to output a motion signal of the vessel;
receiving, by the processor, the motion signal of the vessel;
applying, by the processor, an energy operator to the motion signal to determine an energy signal representative of the environmental condition for the vessel, wherein the energy operator is a Teager Kaiser energy operator, and
classifying, by the processor, the energy signal into a plurality of environmental condition classes for the vessel, each environmental condition class defined by an energy signal threshold value.
