Marine Business

Business Overview

In October 1963, we started the business having obtained authorization from the Ministry of Land, Infrastructure, Transport and Tourism, (former the Ministry of Transport) to perform appraisal and calibration under the Port Transport Business Act. We started at first with draft survey of imported iron ore, coal, etc. and presently we are engaged in loading and condition survey of steel products for export, quality inspection, damage evaluation, hatch inspection, hold inspection, etc. With regard to loading survey, persons who experienced captain and have plenty of knowledge on various products cultivated over many years respond quickly to the customers’ request as marine surveyor.Furthermore, we started to engage without delay in environmental protection related activities of ports and rivers, and are now expanding and promoting various works including inspection for prevention of marine contamination (patent registered), inspection for leak-prevention during refueling, etc. With respect to inspection and evaluation works overseas, we are developing our activities globally utilizing the networks with overseas affiliated inspection companies.
