Summary	Protection of marine technology, e.g. ships, platforms, port facilities, against electromagnetic attacks is a complicated scientific and technical challenge. All these objects have windows penetrable for the electromagnetic effects bringing highly-sensitive equipment out of order. To make windows impenetrable for electromagnetic radiation, shielding glasses should be used instead of conventional ones. At design stage, computer simulation is widely used, which makes design process faster and cheaper. Such simulation could include the assessment of shielding efficiency for a room (e.g. a wheelhouse) with shielding glasses used instead of simple ones. The paper describes an approximate method for simulation of the objects much larger than wavelength of the field, based on Shooting and Bouncing Rays (SBR) method and allowing significant gains in the computer time and memory, as compared to the commonly used Method of Moments (MOM). Software was developed to calculate the distribution of the electromagnetic field levels penetrating into ship rooms via windows and other openings in walls. The method allows consideration of shielding glasses, radar-absorbing paint on walls and other protection tools. To optimize these tools, various values of their parameters are checked.
