This paper presents the results of a feasibility study for a general purpose frigate based on a trimaran hull, developed by Fincantieri and Cetena for the Italian Navy. Particular attention has been given to the structural design of the hull and superstructures. Starting from the results of a previous study, more concerned with the hydrodinamic design of the ship, three configurations of the hulls were chosen for further analysis and the long term loads calculated in several sea zones basing on the results of a 3D seakeeping panel method. A rule-based design of the hull was carried out, using RINA H.S.C. rules; then a 3D FEM model of the whole ship was built to directly assess the hull structure response and adequacy to bending, pitching and prying moments, by using different techniques.

Abstract
This paper presents the results of a feasibility study for a general purpose frigate based on a trimaran hull, developed by Fincantieri and Cetena for the Italian Navy. Particular attention has been given to the structural design of the hull and superstructures. Starting from the results of a previous study, more concerned with the hydrodinamic design of the ship, three configurations of the hulls were chosen for further analysis and the long term loads calculated in several sea zones basing on the results of a 3D seakeeping panel method. A rule-based design of the hull was carried out, using RINA H.S.C. rules; then a 3D FEM model of the whole ship was built to directly assess the hull structure response and adequacy to bending, pitching and prying moments, by using different techniques.
