Contributing to the safety and productivity of energy infrastructure through the power of technology and information.
Amid accelerating global changes—including climate change, environmental and emissions regulations, geopolitical risks, a declining workforce, and the transfer of technical expertise—improving the safety and productivity of energy infrastructure has become an urgent challenge for achieving prosperous lives and a sustainable society.
We stand close to our customers, continue learning from the field, and work together with our group companies and partners both in Japan and overseas to enhance the quality and standards of our work.
By maintaining an integrated understanding of the entire process—from investigation, planning, and design to procurement and construction—we take responsibility for implementing the functions and value embedded in products such as heat exchangers and separation and filtration systems at turbine power generation systems and process plant sites.
Through these efforts, we contribute to improving the safety and productivity of energy infrastructure.
Investigation, Planning, Design, Construction & After-Sales Service
Through close collaboration between our instrumentation, electrical and piping engineering specialists and our group companies — SpaceGrab Co., Ltd. and Yamaguchi Electrical Construction Co., Ltd. — we comprehensively manage the entire process from on-site surveys and planning to design and construction.
By overseeing each stage in an integrated manner, we deliver optimized solutions and aim to be a technology-driven trading company that customers can confidently entrust with their projects.
Benefits of technology & service collaboration within our group (Case studies)
Case Study 01
When upgrading or modifying piping systems in existing plants, it is common practice to conduct on-site surveys manually, measuring and recording the existing conditions.
These collected data, together with the existing drawings, are then used as primary data for planning and design.
In particular, in plants that have been in operation for several decades,
• In many cases, drawings of the existing equipment and piping are not preserved.
• Omissions in on-site surveys and records, or inaccurate measurement results, may lead to rework during the design and construction stages, resulting in additional costs and schedule impacts.
• Due to repeated repairs and modifications as well as long-term deterioration, the actual equipment and piping often no longer match the drawings and P&ID diagrams.
In such situations, capturing point cloud data quickly and comprehensively using a laser scanner with an accuracy of ±1 mm enables the creation of 2D and 3D drawings that accurately reflect the existing conditions.
This approach helps prevent rework in subsequent processes, reduces costs through the review and optimization of planning and design, and shortens plant shutdown periods.
Case Study 02
On construction sites, where conditions change daily, many companies and stakeholders must work together while confronting the risks of serious accidents, and are required to strictly maintain safety management and adherence to project schedules.
With the decline in the working population, the shortage of skilled site engineers has become chronic, making it increasingly difficult to maintain both safety management and adherence to project schedules. This has become a major social issue.
By utilizing point cloud data obtained through surveys and measurements, 3D modeling and construction simulation videos can be created in advance.
These tools enable safety training, confirmation of construction methods and procedures, and project meetings to be conducted beforehand.
As a result, knowledge can be standardized and shared among workers on site, including those with relatively limited experience, while establishing safe and optimized work procedures, leading to reduced labor requirements and the maintenance or shortening of project schedules.
• Omissions in on-site surveys and records, or inaccurate measurement results, may lead to rework during the design and construction stages, resulting in additional costs and schedule impacts.

Our group companies, SpaceGrab Co., Ltd. and Yamaguchi Electrical Construction Co., Ltd., have already achieved proven results on construction sites through the use of construction simulation videos.
Case Study 03
Planned equipment inspections, maintenance, and equipment replacement in existing plants are key to maintaining safe and highly productive operations.
In many cases, plant operations are supported by the dedicated efforts of engineers and managers who have accumulated years of experience and knowledge.
However, the aging of facilities and the shortage of on-site personnel are approaching their limits.
By managing point cloud and 3D data obtained during the construction of new plants or from measurements of existing plants through a cloud-based system, and by inputting and making accessible information for each facility and piece of equipment—such as manufacturer, model, drawings, specifications, installation and operation manuals, and the date of the latest update—planned maintenance and equipment renewal can be carried out without relying on the skills or knowledge of specific key personnel.
