METHOD FOR TESTING OF OFFSHORE ENGINEERING STRUCTURE MODEL IN ICE TRIAL TANK AND DEVICE FOR ITS REALISATION Russian patent published in 2010 - IPC B63B9/02 G01M10/00 

FIELD: construction.

SUBSTANCE: in trial tank, model, for instance platform is rigidly joined to dynamometre, which is fixed to base on tank board on the other side. Bottom imitator is installed under model and is rigidly suspended to base with the help of stands, which are located in stern part beyond model borders, ice field is frozen, which is then pushed up to model by means of towing trolley, and parametres of experiment are registered. Bottom imitator in its front part is fixed to base by means of stands, which pass through tested model. With the help of all these stands, clearance is adjusted and established between imitator and model, and tests are carried out. Device for realisation of such method in trial tank comprises towing trolley with bulldoser for ice pushing up to model, for instance platform, and rigid base fixed on tank board. Tested model is connected to it via dynamometre, as well as bottom imitator with the help of stands arranged in stern extreme end behind model. Imitator in front part has stands, which are joined to rigid base and pass through tested model of platform. It has wells arranged for specified stands. Stands have facilities for adjustment and installation of clearance between imitator of bottom and model, preferably lanyards, in process of tests performance.

EFFECT: invention makes it possible to improve reliability and accuracy of experiment results by provision of accurate positioning of imitator versus model.
