Description

Painting simulation apparatus {Simulation apparatus for painting}

The present invention relates to a painting simulation apparatus, and more particularly, to a painting simulation apparatus helping to train professional manpower capable of performing painting work essential for the shipbuilding industry and the automobile industry.

In the shipbuilding industry, ship painting is evaluated as the most effective method for improving the durability of the hull and the lifespan of the ship.

The International Maritime Organization (IMO) approved ship sulfur oxide (SOx) emission regulations in 2016, and accordingly, from January 2020, fuel for all ships around the world will be converted from bunker C oil to MGO (Marine Gas Oil). Or it was announced that it should be replaced with a LNG (Liquefied Natural Gas) vessel. Such change in ship fuel can be expected to have a positive impact on the ship painting industry by inducing large-scale ship replacement demand.
