Hitachi Plant Construction is making significant contributions to the realization of a decarbonized society through engineering, construction, and maintenance in energy-related businesses such as nuclear power generation, hydroelectric power generation, and power grids that are stable and have high environmental value, as well as transportation businesses that are expected to contribute to solving the problem of global warming. We are also actively developing technologies such as simulation technologies that make full use of digital and virtual reality (VR) technologies, and equipment that can improve the efficiency of on-site work, and aim to become a leading company with our rich experience and advanced technology through engineering and construction technology for social and industrial infrastructure in Japan and overseas.

"All accidents at work can be prevented" - this is the slogan that forms the basis of safety. Safety Management is a division that provides guidance and initiatives to achieve zero accidents and zero injuries as a safety leader, including on-site patrols and safety education under this slogan.
The "Radiation Control" Division is a very important division that provides support to those working under radiation in the execution of nuclear power projects, including radiation measurement and evaluation of the work environment using radiation measuring instruments, planning for the appropriate wearing of personal dosimeters, and evaluation of exposure doses.
We have a long history in the Nuclear Power Business. In 1970, we began construction on the Tsuruga Nuclear Power Plant No. 1 for The Japan Atomic Power Company, which contributed to nuclear power generation in Japan. In addition to this extensive experience, we also take advantage of our propriety technology, methods, and products to achieve businesses with a higher level of safety and efficiency considerations.We handle a wide range of nuclear power plant operations from installation plans and building construction (planning, fabrication, and installation) of the primary equipment in nuclear power plants, such as reactors, turbines and generators to nuclear power fusion research and nuclear fuel reprocessing facilities. We also provide preventative maintenance (modification, renewal, and repair work)
Substations are indispensable to supplying high-voltage power generated by power plants for consumers to use. These facilities are not only necessary to power infrastructure but also require a high level of reliability and safety. Our Substation Business mainly installs substation equipment, handles the civil and construction work, and designs, constructs and delivers steel towers and other auxiliary equipment.
Through this wide range of work, We contribute to the construction of facilities that can supply safer, more reliable power by considering the most efficient construction methods capitalizing on extensive experience and specialized knowledge while using its unique strengths in operational support systems taking advantage of IT.
Our Substation Business has earned high praise from its customers and has expanded its business domains not only in Japan but also overseas.
Railroad businesses are expected to help address climate change as a highly energy-efficient means of passenger and cargo transport with a low environmental burden. Countries worldwide are advancing their railway infrastructure as well to alleviate road congestion.We engage in businesses that contribute to the growth of railroads in a sustainable society through the delivery of rolling stock maintenance systems as well as installation and construction of electrical equipment as power supplies essential to railroad administration.
We have an extensive track record overseas, especially through our involvement in overseas projects. We are one of a few companies launched in Japan that can provide total solutions for rolling stock maintenance in overseas projects.
The modern world is hastening initiatives to achieve a decarbonized society worldwide with greater emphasis on renewable energy free from greenhouse gas emissions. Solar PV, wind, and hydro power generation as well as other renewable energies provide a low-carbon energy source for production in Japan. The nation is continuing to spearhead initiatives toward a stable supply of these types of energies.
We have consistently expanded the construction of power plants as its core business. We leverage the track record, knowledge, and expertise that we have cultivated in the energy business over so many years in the renewable energy domain. Our advanced installation technologies support a wide range of customers through our wealth of experience as well as research and development for equipment installations. Even in the renewable energy field which contributes greatly to society, we provide installation work suitable to customer requirements.
When cutting with a band saw, the following problems can occur: (1) the blade getting caught in the object being cut, (2) extreme bending, and (3) significant blade damage. We have obtained prospects for realizing automatic operation logic that detects and avoids the above problems, including the blade getting caught in the object being cut, extreme bending, and significant blade damage. As a result, we expect to be able to reduce the number of personnel required for monitoring by 75%.
Electric power companies are working to reduce costs in response to nuclear power regulations. In response, we have developed a new three-dimensional equipment seismic isolation system with a seismic isolation structure that meets seismic resistance requirements, which integrates a vertical seismic isolation mechanism that uses constant load springs and movable pulleys for load support, coil springs for restoring functions, and a horizontal seismic isolation mechanism that uses cross-linear bearings, etc.
To address issues such as the lack of analyst resources, the creation and review of a huge amount of inspection evidence, and the maintenance of the quality of work permit analysis, we have developed systems that use AI to automatically extract similar models from previous models, systems that automatically re-analyze load replacement, and systems that visualize the results of analysis model 3D shape display analysis by color.
We have developed a simulator that checks the feasibility of lifting and carrying operations, a function that creates lifting and carrying animations while checking a full-scale 3D model superimposed on the site using a mixed reality (MR) device, and a function that measures the distance between the 3D model and any obstructions in the field and automatically displays the distance to the obstructions on the system's screen.
When transporting and installing equipment in high-radiation areas at the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Station, it is difficult for workers to carry the ropes attached to suspended loads and to control the direction of the suspended loads while transporting them. Therefore, we developed a device that can remotely control the rotation of suspended loads, which we named "Hachidori" (hummingbird) because of its ability to stop the rotation (movement) of suspended loads, and we are using it at the site.
The number of accidents on construction sites is increasing due to factors such as a decline in the number of workers and skilled engineers, so there is a need to promote collaborative safety measures that use ICT to share information about people, materials and the environment. This technology uses image information from fixed-point cameras and AI analysis technology to (1) recognize people and materials, (2) determine the relative position of the two and assess the risk, and (3) issue an alarm to draw attention to the situation.
In the construction industry, the number of older workers is increasing and the number of younger workers is decreasing, and it is predicted that a large number of skilled workers will retire in the future. In this situation, skilled workers and laborers often move from site to site, and since the transfer of know-how is not efficient, we have built a foundation for the transfer of skilled workers' know-how using digital technology.
