DEVELOPMENT AND VALIDATION OF MATHEMATICAL MANOEUVRING MODELS USING DATABASE TECHNIQUES

This paper describes the modular set-up of the simulation models in a ship simulator systems in relation to databases and tools for modelling and validation models. For reasons of scalability and flexibility, the ship manoeuvring models in the simulator system are of a modular type. The major components of the ship models are the mathematical manoeuvring model, the engine room model and the autopilots. These submodels are also of a modular type. For the manoeuvring model this means that it is modelled by a standardized framework consisting of a number of modules each describing a separate force or hydrodynamic effect acting on the ship. The modular approach offered a basis for defining databases and tools for preparation and maintenance of ship manoeuvring models. The main database stores the structure of the mathematical manoeuvring models, as they are built up of modules, together with an extensive ship description. The modules themselves are stored in a separate database, together with extensive module descriptions. The ships database and the module database both keep track of a database containing towing tank data, full scale data and references to other data for different ships and ship types, which can be used for identification and validation purposes. Together with the tools for maintaining and building these databases this creates a way of flexible ship modelling.
