||This paper describes a procedure to obtain an improved linear design model for
Wave Filtering (WF) and Dynamic Positioning (DP) of ships and offshore rigs subjected to the
influence of sea waves. The proposed model captures the main physics of the problem and allows
for the design of advanced control and estimation algorithms to solve the WF and DP problems.
Numerical simulations, carried out using a high fidelity nonlinear DP simulator, illustrate the
performance improvement in wave filtering as a result of the use of the proposed modified model.
