1. Surface of the launching track (slip) must slope towards the water and go into the water at a certain depth. The slope of tracks depends on the launching weight of the vessel. The slope is determined by ratio of the height of full raise to the length of the slip. The value of the slope for a variety of slips depends on the size of vessels to be launched:

the slope for small vessels is from 1 : 8 to 1:12

the slope for middle vessels is from 1 : 14 to 1:16

the slope for big vessels is from 1 : 18 to 1:24

Before the operation it is necessary to clean the slip surface removing foreign objects (like metal, broken glass, nails and some other sharp objects) that may damage the bag shell structure and to level the surface with sand (removing the pits and hills).

2. During the operation is not allowed:

• exceedance of the working pressure in the bag shell;

• lifting of loads which exceed the weight carrying capacity bags;

• moving or dragging bags on surfaces, which can damage the bag;

• rolling bags when the lifting height is less than 400 mm;

• storing bags inflated for a long time.

3. When using the bags the perpendicularity of the axis of the vessel to the axis of the bag must be strictly observed.

4. The physical impact on the outer surface of the bag is prohibited because of the risk of the destruction of the layers and the break.

5. By launching, upgrading and transporting of the vessels the parallelism and at most 6 meters intervals between the airbag axes is to be adhered, if the operations are carried out without the development of special methods of launching, upgrading and transporting of the vessels.

6. When transporting the vessel on bags the bags should be placed in strict compliance with the schemes specified in the project documentation.

7. Use of docking ships deflated pneumatic marine rubber airbags for other purposes is prohibited.

8. Deflated pneumatic bags are slid under the ship and inflated with compressed air, carrying out the transfer of the vessel from the construction area to the launching device. The launching is made on the air bags used as the rollers. This launch can be both uncontrolled and controlled. In the latter case the launching speed is regulated by the traction mechanism which is located at the head of the slip.
