Development of frigate designs with good seakeeping characteristics

The paper summarises a design study of advanced mono-hull frigate concepts. Based on the parent design of a 120 m frigate, seven different alternatives of hull forms and concepts have been developed. The concepts have been evaluated according to their performance as regards a) ship motions in head, following and stern sea, b) linear operability for the North Atlantic and c) bare hull resistance and added power in head seas. The work was done as part of the THALES programme, which is a project with the Danish Naval Materiel Command (Denmark), FORCE Technology (Denmark), INSEAN (Italy), Italian Navy (Italy), MARIN (the Netherlands), Royal Netherlands Navy (the Netherlands) and Delft University of Technology (the Netherlands). The THALES programme has been completed in the period 2000-2004.
