“…In contrast to the mature discipline of the statistical prediction of waves (Pierson et al 1955;Kinsman 1984;Tucker and Pitt 2001), this is a relatively new area with a very modest-sized literature (Morris et al 1992(Morris et al , 1998Prislin et al 1997;Zhang et al 1999;Belmont et al 2003Belmont et al , 2006Wu et al 2000;Edgar et al 2000;Janssen et al 2002;Wu 2004;Blondel et al 2008;Naaijen and Huijsmams 2008;Naaijen et al 2009;Abusedra and Belmont 2011) that is only beginning to make the move from a research topic into practical applications.…”

“…Given that the measurement horizons for these techniques are of kilometer scale, this produces maximum predict-ahead times of the order of 1 min, meaning that all data processing and prediction model building must be completed in a few seconds. Thus, while work has been undertaken on nonlinear DSWP (Prislin et al 1997;Zhang et al 1999;Wu et al 2000;Wu 2004;Blondel et al 2008), the need for short computational time scales means that generating nonlinear multidirection prediction models is unrealistic without supercomputer resources. So, for most practical maritime operations, real-time DSWP is restricted to using linear sea models (Morris et al 1992(Morris et al , 1998Edgar et al 2000;Belmont et al 2003Belmont et al , 2006Abusedra and Belmont 2011).…”

For a number of maritime tasks there is a short time period, typically only a few tens of seconds, where a critical event occurs that defines a limiting wave height for the whole operation. Examples are the recovery of fixed and rotary winged aircraft, cargo transfers, final pipe mating in fluid transfer operations, and launch/ recovery of small craft. The recovery of a 30-t rescue submersible onto a mother ship in the North Atlantic Treaty Organization (NATO) Submarine Rescue System is a prime example. In such applications short-term deterministic sea wave prediction (DSWP) can play a vital role in extending the sea states under which the system can be safely deployed. DSWP also has great potential in conducting experimental sea wave research at full scale. This report explores the feasibility of using data from an experimental wave profiling radar in achieving DSWP. The report includes theory, simulation, and field testing. Two forms of DSWP are employed: a fixed point system based upon a restricted set of wave directions from which some success is obtained and the other a fully two-dimensional technique that requires further development. The main finding is that using wave profiling radar for DSWP offers promise but requires improvements both to the spatial reliability and the resolution of the wave profiling radar and to the temporal resolution of its sweep before the technique can be considered to be viable as a usable tool.

SummaryOcean waves can be explained in terms of many factors, including wave spectrum, which has the characteristics of wave height and periodicity, directional spreading function, which has a directional property, and random phase, which randomly represents a certain property. Under the assumption of a linear system, ocean waves show irregular behaviours, which can be observed in the forms of wave spectrum, directional spreading function, and complex phase calculations using the method of linear superposition. Ocean waves, which include a variety of periodic elements, exhibit direct proportionality between their period and propagation velocity. The purpose of this study was to understand the phase components of the period and to make exact calculations on the deterministic phase in order to make predictions on ocean waves. However, measurements of actual ocean waves exist only in the form of information on wave elevation, so we faced an inverse problem of having to analyse this information and calculate the deterministic phase. Regularization was used as part of the solution, and various methods were used to obtain stable values.
