STXM was retained by Ingalls Shipbuilding (Northrop Grumman) to complete the structural design of the vessels. STXM performed all structural calculations, developed all structural plans and built Finite Element Models for submission to and approval by Class. In what STX Canada Marine believes to be another first for an American yard, these ships were built to dual class under both Lloyd’s Register and American Bureau of Shipping rules. The use of the Finite Element Analysis reduced the structural weight by as much as 2,500 tonnes for a vessel of this size. The structural weight is in the order of 50% of the vessel’s Lightship weight, of which a third can be superstructure. The ability to minimize the structural weight enables the owner to maximize the passenger capacity and earning potential of the vessel. |
The structural analysis is a major task on a vessel of this size. STXM is excited to have participated in this monumental project and to have been a part of Project America.
