There has been presented a new procedure of the seating of a combustion engines at the marine power plant with steel chocks cemented by a thixotropic polymer composition between the engine's spot footing and the foundation ledge. A combustion engine is seated on foundation at the marine power plant by steel chocks or the chocks that are cast from polymer composition at the marine power plant. The arrangement, number and dimensions of foundation chocks, as well as arrangement, number and dimensions of the lateral and frontal stoppers that secure chocks work, are established by an engine manufacturer and are approved by Classification Society that supervises the vessel's construction and operation. The author's intention was to develop such chocks that combine the good resistance of steel chocks with the easiness of adjustment the bearing surfaces of polymer compositions chocks. Combination of these features was obtained for steel chocks which are glued by the relatively thin layers of polymer compositions between the engine spot footing and the foundation ledges. Such a method of making the chocks and seating with them the engines on foundation was claimed with the Patent RP No. 192120 on 24th July 2000 for the Polish Naval Academy. In order to receive the approval of the Polish Register of Shipping to use new chocks at the marine power plants, the author carried out appropriate research, results of which are presented below. The results obtained in the research show that by seating of a combustion engine with these steel-thixotropic polymer chocks at the marine power plant, the foundation bolts tension can be diminished to the value equal to five times of the engine weight.
