Special coating process of cargo tank of product tanker/chemical tanker

Abstract

The invention discloses a special coating process of a cargo tank of a product tanker / chemical tanker. The process adopts an integral method instead of an upper and lower part method and has the effects of meeting the construction requirement of the special coating, shorting the special coating period, improving the special coating efficiency, lowering the special coating cost and ensuring smooth special coating construction. The process specifically comprises the concrete steps of protection of fittings and piping systems in a cabin, scaffold setting up in the whole cabin, advance sand blasting in the whole cabin, main sand blasting in the whole cabin, dust absorption and surface treatment inspection in the whole cabin, first coating of the whole cabin, cabin bottom protection, upper part painting, upper part film painting and repairing, upper part film painting inspection, scaffold dismantling, lower part protection removal, treatment of the support point of the lower scaffold; lower surface cleaning and inspection; and lower part painting, lower part film painting and repairing and lower part film painting inspection. The process has multiple considerable effects such as high efficiency, low cost, energy conservation and the like and has the effects of not only ensuring smooth completion of special coating of the 110,000-ton large product tanker but also creating considerable economic and social benefits.

Description

technical field [0001] The present invention relates to a process method of special coating, more specifically, relates to a coating method of a special cabin of a ship. Background technique [0002] For the special coating of liquid cargo tanks of 110,000-ton large-scale product oil tankers / chemical tankers, according to the construction conditions and equipment applications of the shipyard, the requirements for the special coating construction process are also different. It is necessary to formulate and implement an excellent special coating construction process to achieve Relevant technical requirements to ensure the construction of special coatings. [0003] Specially coated / specially coated tanks refer to: the cargo oil tanks of product oil tankers or chemical tankers. Due to the needs of loading various types of product oil or chemicals, the steel surface of cargo oil tanks must be coated with special coatings for protection. The whole process of construction for this...

Problems solved by technology

[0009] Second, during the sandblasting construction of the lower part, the surface of the upper paint film is polluted (because the upper paint film has been completed and handed over for inspection), the whole cabin must be washed with water before the sea trial, which leads to a longer construction period of the special coating. Increased the cost of special coating such as whole tank washing water
