Company information
Marine Works Co., Ltd. is a diving company that conducts construction and surveys not only in its local area of Kyushu but also throughout Japan. Our meticulous work, which is highly regarded in repair work for ports and bridges, as well as deterioration surveys of underwater structures (steel and concrete), is a key selling point of our company. As the aging of port infrastructure progresses and attention is drawn to disaster prevention in coastal areas, the demands for underwater work are becoming increasingly diverse and sophisticated. In response to this situation, we have secured experienced divers and land surveyors. In addition to essential equipment such as diving vessels, various compressors, and hydraulic core machines, we are equipped with a wide range of the latest equipment to respond quickly and reliably to various requests. Please feel free to consult with us, as we have established a consistent operational system for investigating, planning, executing, and managing port-related projects, whether underwater or above water.
