The System Of Preventative Repair

In accordance with these river vessels are subjected to preventative (current, average, major) and unplanned (restorative, emergency supports and warranty) repair. Volume and frequency conduct preventative repair (PPR) shall be fixed on scientifically sound standards of wear, according to excellence of work crews and the results of systematic observations of the assemblies and parts of spp during their operation. Current shipbuilding produce annually or once every two years. It is performed in (winter) period. Such repairs should be completed by the opening of navigation. In the current ship repair restore or replace with new individual and wear parts, and produce mostly tuning by ship crews. Ship Repair Yard in the current repairs of the vessel carries only those works for which you want to plant equipment.

In vessels with a two-year intervals between the current ship repair in the fall and spring of that year, when the current shipbuilding do not produce, ship crews and the bpu implement the fall-spring maintenance of the fleet. In this case, maintenance costs should not exceed 60% of routine repairs. The main type of bpd (repair) is the average repair. In Depending on the purpose, power and capacity of vessels average repair repair companies perform in 4-6 years. With good technical condition of the vessel and its machinery average ship repair can be carried out and a longer period of time. During the mid-repair is carried out: measurement and fault detection of all the details of marine diesel engines, bore cylinder bushings or replace them; groove or replace the pistons with piston rings and fingers replacement rod bolts and individual cylinder heads; fuel equipment and parts Timing; perezalivku rod bearings main bearings and separate; centering axes of the cylinders and shafting, and other operations, providing the power plant efficiency and maintaining its operational and technical qualities to the next repair - mean (or capital). As well as current, average ship repair operates in period. It should be completed by the opening of navigation.

Overhaul of the vessel is carried out in 12-16 years of its operation after construction. Depending on the technical condition of the vessel and opportunities shipyards deadlines overhaul may be extended by the conclusion of a special technical committee with representatives from the shipping company inspection River Register rsfsr. Overhaul produce forces and means of shipyards, and its costs should not exceed 40% of the construction cost of the vessel. When major repairs replace all worn parts, machinery and equipment power plant and restore the strength of the hull with the replacement of metal structures. During the middle and major repairs inspect and repair the underwater part Corps, for which the court carts on inclined rails, lowered into the water, pick up on the shore (slip) or injected into the dock. When capital and average repair is usually performed upgrades and renovations (Reconstruction) of ships. By modernizing include work carried out to improve the performance of courts, their technical and economic performance, increasing productivity or culture transport, protection waters from pollution, changes in working and living conditions of ship crews and other modernization works to improve conditions of life and work crews can be done also for maintenance. Conversion (Reconstruction) in order to produce a partial reconstruction of the vessel, for example, changing its destination, navigation area, type of power plant.
