Japan's Shipbuilding Industry Wants To Compete With China And South Korea With Cutting-edge Technology.

New shipbuilding market downturn in the current environment, to improve the work efficiency and make up for the defect of understaffed, shipbuilding industry hope with the help of information technology (IT), virtual reality (VR) system, such as digital technology to improve productivity and better compete with China and South Korea shipbuilding industry.

Government financial aid to develop digital shipbuilding technology.

The Japanese shipbuilding industry has been hit hard by the rising yen and slowing economic growth. The number of Japanese yards has dropped sharply this year after environmental regulations pushed up new orders. Previously, Japan's ministry of land and transport introduced the i-shipping concept to the shipyard. This concept is the Internet of things, big data technology used in ship operation and maintenance, through the timely feedback information to achieve the effect of design, construction, operation and maintenance of the integration, improve the competitiveness of the products.

Earlier this year, Japan's transport ministry launched a financial assistance program, provide for shipbuilding industry in the current fiscal year 350 million yen ($3.1 million) fund, to promote the development of the shipbuilding industry digital technology such as the Internet technology and the Internet of things.

The Japanese government hope that through this project, using digital shipbuilding shipbuilding industry to improve the production efficiency, farewell with the shipbuilding cost competition, strive to achieve the goal of 33% market share in 2025.

In order to achieve a 33 per cent market share target, Japan's shipbuilding industry must further strengthen its high productivity levels, according to the ministry of land and transport. According to clarkson, Japanese ship companies now account for 23 per cent of global market share.

The project aims to increase the workload of one worker to 250 GT by 2025, 50 percent more than in 2014, and again to enhance the competitiveness of Japanese ships.

At present, the ship companies in Japan are working to develop technology including three-dimensional driven design scheme of automatic welding technology, artificial intelligence used in precision measurement of laser technology and application in the process of production management IC tag and unmanned aircraft.

This kind of automatic change can also help the ship enterprises to overcome the shortage of labor force and the aging of the workforce. However, some of the old problems with the design of Japanese shipping companies may make it unsuitable for the application of digital construction technology.

The shipyards develop VR and AR systems.

It is understood that mitsui shipbuilding is assisting the Japan ship technology research association to develop a system capable of analyzing workers' actions. Several cameras installed on the job site will use the color and intensity of the light to grasp what the workers are doing. These results will be linked to pick up the range of sensors and communications at the worker's smartphone, welding equipment, and other devices on the data from radio frequency identification tag, the combination of dynamic and position of the workers.

These data analysis results will help the shipyard reconfigure the operating procedures, and furnish the equipment and industrial equipment to reduce the working time by up to 40 per cent, depending on the shipyard. This system will be applied to the welding and polishing process of steel plate parts.

The Japan ship technology research association will invest 45 million yen ($448,000) in research and development, as well as the village shipbuilding and sumitomo industries. The Japan ship technology research association is composed of 185 groups and enterprises.

Changshi shipbuilding is using virtual reality simulation to upgrade coating process. Using a large screen, 3 d glasses and spray gun, hull virtual reality images of projection screen coating operation, through the analysis of the operation to determine whether the coating evenly, and will feedback the results and improve the area to the workers.

Changshi shipbuilding has established the evaluation criteria related to this new virtual reality system. Changshi shipbuilding plans to reduce the cost of coating the midsize bulk carriers, which cost about 60m to 70m yen for each medium bulk carrier.

Fujitsu and other companies are developing augmented reality (AR) systems to support tanker construction. By using a smartphone or tablet camera to view the pipeline, workers can retrieve the installation location and procedures of the relevant pipelines, as well as other reporting data. An oil tanker contains between 7,000 and 20,000 pipelines, and the new system can reduce the confirmation time of each line from 10 minutes to about one minute, thus improving operational efficiency.
