The experience of our ship repair plant shows that it is advisable to concentrate the production of all documentation for the current repair of a vessel in one group — the defect group. This ensures the completeness of the documentation, shorter production time (standard sketches and other standard documentation) and greater clarity in the work (reduction of excesses, intermediate links in the process of manufacturing the drawing). At the same time, the employees of the design bureau are not distracted, as they were before, from making more complex and time-consuming drawings for capital and medium repairs.
Currently, we have set ourselves the task of bringing the ship's defect period to 5-8 days, so that the last billet arrives at the machine shop on the 10th—12th day after the arrival of the ship. And it is still not uncommon for blanks to arrive at the machine shop almost throughout the entire repair. However, based on the experience of repairing the steamships Lyuban, Volochaevsk, Kapitan Gastello and others, we have already achieved a reduction in the duration of defects during current repairs to 5-10 days.
Ideally, the current ship repair should be limited to hull repairs, installation work on equipment and other work carried out mainly on the ship with a minimum number of newly manufactured parts. Specialization and cooperation should ensure the availability of ready-made parts, products, assemblies and mechanisms in the warehouses of ship repair plants, which will be installed on the ships under repair. Timely completion of standardized parts, products, assemblies and mechanisms is considered as the "zero stage". However, currently our factory, with the exception of fasteners and fittings, has to manufacture almost everything that has to be installed on ships. In these conditions, the "zero stage" of ship repair is carried out by the plant itself.
The initial data for compiling the nomenclature of the "zero stage" of ship repair for each plant can serve as statistical data on the manufacture of various parts and assemblies during ship repairs in previous years. The same data allows you to determine the required quantity (minimum warranty). certain details included in the nomenclature.
Thus, the "zero stage" of ship repair according to our technology consists of three main parts.
1. Blanks, castings and forgings for the repair of main and auxiliary mechanisms.
2. Standardized and normalized standard ship parts, products, and assemblies.
3. Large complex nodes.
The experience of defective mechanisms of several dozen vessels shows that 50-75% of blanks during current and average repairs of mechanisms are piston rings, grundboxes, bearings, metal packing, stuffing boxes, spool bearings. As a result of the study, defects of the main and auxiliary mechanisms (steam engines, winches, windlasses, pumps, etc.) were carried out, and a range of standard sizes of blanks for some of the above-mentioned parts (piston rings, metal packing, grundboxes, stuffing boxes, bearings) was developed. Each standard size has its own cipher. Many blanks are heat-treated in advance and tested for hardness, which not only speeds up their entry into the machine shop, but also prevents defects.
The production of blanks of the "zero stage" of ship repair is carried out using the necessary equipment (centrifugal casting, coquille), which allows them to be mass-produced. All these details are combined into 5 albums released by the technical department of the plant: device details (staples, couches, lanyards, bales, etc.); useful items (necks, doors, ladders, hatches, etc.); furniture (armchairs, chairs, shelves, frames, etc.); details for dov pipeline (couplings, plugs, nipples, settling tanks, fittings, etc.); parts for repairing mechanisms (purge taps, pressure gauge taps, lubricators, oil cans, etc.).
