Reducing the physical burden of maintenance work, lowering reliance on skilled labor and improving safety
First written in FY2016. 8 of 9 entries say "Advanced", first in FY2017. Latest entry: FY2026.
The whole theme swung hardest in 2023: 1 of 10 companies on the "Worse" side.
15 other companies' latest entry also says "Advanced".
- FY2026AdvancedAnnual report
「During the period, we produced a prototype and confirmed its operation at the plant, completing verification of defect-detection accuracy and other factors. In the next period, we will continue improving running stability and optimizing the body while working toward on-site deployment.」
The tank bottom-plate inspection robot completed prototyping, in-plant operational testing and verification of defect-detection accuracy, and moved to the improvement stage ahead of on-site deployment. We also conducted testing and evaluation using the actual automated tube-cleaning machine. - 2026-05-13AdvancedEarnings presentation
「ENEOS株式会社の川崎製油所にて、内面自動洗浄機による熱交換器の実機洗浄を実施」
熱交換器チューブ自動洗浄技術が実機での洗浄実施段階に進み、安全性、品質安定性、作業効率の向上効果を示した。 - FY2025AdvancedAnnual report
「During the period, we evaluated the effectiveness of the MAUS GRIPPUL, equipment for retubing, through tests using the actual machine at our training facility and through ferrule-removal work at planned maintenance shutdown sites, confirming the advantages of mechanization.」
The company conducted tests using actual machines and on-site evaluations of mechanization technologies, moving toward packaging the equipment and deploying it on site in the next period. It has also expanded its efforts to automated tube cleaning, water-jet cutting, automated tank welding and inspection robots. - FY2024AdvancedAnnual report
「As the equipment is now operating reliably and its application track record has grown, we will transfer it to our affiliate 港南通商株式会社 and promote the wider adoption of cutting work using cold-cutting technology.」
Following the stable operation and growing application record of the water-jet cutting machine, the company is moving to the transfer and wider adoption stage through an affiliate. It also automated heat-exchanger work and evaluated the on-site application of an automated cleaning machine. - FY2022AdvancedAnnual report
「We established a flame-free cutting method as a safer and more efficient process by adapting existing products. Going forward, we will accumulate on-site experience and work to standardize these methods. During the period, we examined welding conditions and conducted experiments to expand automated welding of tank shell plates to vertical joints.」
The company established a flame-free cutting method and proceeded to examine conditions and conduct experiments aimed at expanding automated welding of tank shell plates to vertical joints. By contrast, on-site application of automated welding to piping remains highly challenging and has not yet been introduced. - FY2021AdvancedAnnual report
「Having verified the effectiveness of water-jet cutting on site, we will accumulate further application experience and continue making improvements from the next fiscal year onward, with the aim of offering a comprehensive range of cold-cutting technologies, including existing technologies. During the period, we examined welding conditions to expand automated welding to vertical joints. We also worked on automated welding of tank roof plates and confirmed that there were no issues with on-site execution.」
Following on-site verification of water-jet cutting, the company is moving toward accumulating application experience and offering it as a standard option. For automated welding, it examined expansion to vertical joints and confirmed on-site execution on tank roof plates. - FY2020AdvancedAnnual report
「We introduced a cutting machine using water jets as a completely flame-free method, applied it for the first time on site to cutting large-diameter piping and verified its effectiveness. We applied it to partial replacement work on the upper shell plates arising from tank internal inspection work. In addition to the current horizontal joints, we intend to expand its application to vertical joints.」
The company proceeded with the first on-site application of flame-free cutting equipment and on-site application of automated welding for tank shell plates, and plans to expand the welding technology to vertical joints. - FY2017AdvancedAnnual report
「This initiative improved work safety and increased the equipment application rate. We introduced flame-free cutting and beveling equipment and applied it to the cutting and beveling of high-pressure, thick-walled piping, which had previously been extremely time-consuming, substantially shortening the process.」
In addition to increasing the application rate of construction machinery, the company substantially shortened processes by introducing flame-free cutting and beveling equipment. - FY2016First statedAnnual report
「We designed and manufactured a compact, lightweight hydro extractor suited to domestic facilities. This reduced the physical burden of work and created an environment in which work could be performed safely with limited experience. The equipment was scheduled for immediate use in planned maintenance shutdowns in fiscal 2016.」
The company is developing technology to reduce the physical burden of work and reliance on skilled labor by making construction equipment smaller and lighter.
