Part B: a review of the real-time sea state estimation, using wave buoy analogy: a decuple benchmark and future outlook

Environmental knowledge in the maritime industry is of crucial significance for enhancing efficiency, increasing safety, and boosting interoperability. Among proposed tools and methods for estimating the seaway, wave buoy analogy has successfully drawn attention spans owing to the extensive advantages, while it has not been utilized yet in the industrial platforms. In addition, since each technique approached the problem differently, comparing methods is quite hard to elaborate. To this end, after summarizing all available models and the existing challenges in the realm of real-time estimation in the first paper, the present issue aims to propose some decuple criteria for evaluation of not only all available techniques but also a framework for assessment of any seaway estimation model in the future. For this sake, besides rating the existing techniques, a Fuzzy Analytical Hierarchy Process (F-AHP) has been adapted, and the potential candidates for further development are introduced accordingly. Further, the effort has been concentrated toward excavating all technical nuances and discussing how they could be developed in the future. The outcomes of the present paper following the first paper can give a deeper insight into the wave buoy analogy from a broader perspective and further paves the road for future strides.
