HMS Victory

Fenton Holloway carried out a structural analysis of HMS Victory for the National museum of the Royal Navy via prime contractor BAE Systems. The purpose was to establish the current strength of the ship and to provide guidance as to the most beneficial repairs and replacement. In order to carry out a meaningful structural analysis it was necessary to construct a digital model of the ship, originated from laser scanning, as well as collecting data from other sources such as repair records, shipwrights’ surveys and recorded movement data. This data was collated and incorporated in the analytical model. In a parallel exercise an ‘Intelligent model’ was constructed to provide a readily accessible database which contains the dimensional and location information for all (28,000) structural elements in the ship with the facility for the addition of other information such as material, date of replacement/repair, etc. Where possible, repair data relevant to the ship’s hull was inserted in the database as it was also processed to inform the structural model. The analytical model construction was a major exercise requiring extensive manipulation of the ‘solid model’ produced from the scans to produce a wireframe model to allow analysis of the complete structure. The analysis was carried out using ANSYS with a very large model simulating the assembly and condition of all the elements in the ship. The results of the analysis showed the ship to be stable and capable of resisting foreseeable short and medium term loadings without distress. However the work indicated the necessity to provide a more ‘sympathetic’ support system to the historic hull, which we are currently designing.
