Abstract: FIELD: shipbuilding. 
     SUBSTANCE: invention relates to ship building, particularly, to ship lifting and rescue operations. Ship-lifting system comprises a cross member in the form of a closed pipe, internal partitions divided into ballast tanks, wherein gas generators are installed in medium lateral and end tanks to disengage during lifting due to roll or trim at elevation. In the lower part of the closed pipe there is a platform, to which the gripping device working elements are attached, made in the form of a hollow rod hinged to the intermediate and end support cantilevers, interacting with closed anchor chain, which is fixed on end console on one side, and on the other side is engaged with sprocket installed on lower platform of hydraulic windlass. Solid-fuel gas generator contains cylindrical stick of unitary solid fuel, on the upper end of which there is a localiser of the combustion zone in the form of a balancer, which consists of an inverted heat-resistant cup with an electric heater, a bracket, a hinge with an attached rigid rod with a buoyancy element and a counterbalance. Before lifting operation in end and two middle side ballast tanks solid-propellant gas generators are arranged, having total gas-forming capacity sufficient when filling said tanks to overcome tear-off resistance. And during the process of deepening the support cantilevers into the sludge, the preset direction of the ship lifting system is maintained by bending and unbending those gripping device working members, which are lagging behind the rate of penetration. These actions are carried out until complete coverage of the lifted object, and then, by blowing the main ballast tanks, a force is created, which is equal to the design lifting weight of the lifted object, then voltage is simultaneously applied to all solid-fuel gas generators. 
     EFFECT: higher efficiency of ship-raising operations.

Multilayer coating film comprises a glossy layer, which contains a glossy material and is directly or indirectly formed on the surface of the coating application object; and the colored layer, which is semitransparent, contains a reddish pigment and is layered on the glossy layer. In the multilayer coating film, the glossy layer satisfies the following conditions with respect to the Y value calibrated with the standard white plate in the XYZ colorimetric system: Y(10°) is 50 or more and 950 or less; Y(25°)=k×Y(10°), where k is a coefficient and is 0.05 or more and 0.35 or less, wherein Y(10°) denotes the reflected light value Y, measured at angle of 10° receiving light (angle of deviation towards light source from mirror reflection angle). Y(25°) denotes the reflected light value Y, measured at angle of 25° receiving light when the angle of incidence of light is 45° (angle with deviation by 45° from normal to surface of glossy layer). Inclination of the tangent to the spectrum of spectral transparency of the colored layer at wave length 620 nm, defined as the absolute value, is 0.012 nm -1  or more and 0.03 nm -1  or less. Spectral transparency is obtained by dividing the spectral reflectivity measured for the colored layer applied on the glossy layer at angle of 10° receiving light when the angle of incidence of light is 45°, on the spectral reflectance measured for the glossy layer with the removed colored layer and, respectively, the exposed surface at angle of 10° receiving light when the angle of incidence of light is 45°.
