Adaptive Sea State Estimation Based on Ship Motions in Semi-stationary Sea States
Environmental information is critical for ensuring the safety of complex marine operations (e.g., offshore crane operations and dynamic positioning), with waves being the primary external force affecting floating structures. Accurate sea state estimation (SSE) not only significantly enhances operational efficiency but also serves as vital support for real-time decision-making and risk control. The wave buoy analogy (WBA) utilizes ship motion data to estimate wave energy distribution; due to its cost-effectiveness, flexibility, and lack of need for additional sensing equipment, it has gradually become one of the most important real-time monitoring methods in the field of ocean engineering.
