Quality Control

As a corporate group that is trusted by people and contributes to society through its engineering and services, MITSUI E&S Group aims to offer high-quality products. Always thinking from the customer's perspective and acting quickly, we ensure that the specifications agreed upon with customers and all applicable laws, regulations and standards are met. Further, we operate a quality management system that enhances the quality of our manufacturing processes. We also develop and operate digital technologies such as failure prediction via remote monitoring systems and data analysis and drone-based inspections to maintain and improve quality during the use of a product.

Initiatives for Quality Control

Quality management system

Both Tamano Works and Oita Works have acquired ISO 9001 certification, are regularly reviewed and effectively and properly operate a quality management system.

Quality inspection and prevention of recurrence

In the manufacturing stage, the design division leads continuing the activities to develop and establish the quality of products at an early stage. This involves, for example, the sharing of construction-related information and risks with the departments and companies involved to engage in array of verification activities beforehand. After product delivery, the after-sales service division takes the lead in the gathering of a variety of information about problems that occur after a product begins operation and the provision of feedback for upstream processes, mainly design. In this way, we implement a PDCA cycle as we strive to continually improve the quality of our products.

Digitalization of the monitoring of product operating conditions

Our products can be equipped with systems to monitor their operating conditions. This enables users to analyze the monitoring data, predict failures before they occur, share data with our engineers and ensure they are able to quickly recover following a failure.
