周囲を海に囲まれた日本にとって、

国内外の海運を支える造船業は必要不可欠です。

内海造船は1940年の創業以来、国内フェリーをはじめ、コンテナ船、バルクキャリア、タンカー、自動車運搬船、RO-RO船など多彩な船種の建造、それらの船種に加えて官公庁船、練習船、特殊船等の修繕を手掛け、海上輸送を支えてきました。多種多様な船種を建造することであらゆるニーズに対応するのはもちろんのこと、排ガスに含まれるNOx(窒素酸化物)やSOx(硫黄酸化物)の排出規制をはじめとしたルールの改正によって新たに必要となる修繕にも対応しています。新造船事業と修繕船事業の2つの柱を強みとして、世界の海運に貢献していきます。

The shipbuilding industry is of vital importance for Japan, a country surrounded by the ocean, since it represents the pillar of the archipelago’s domestic and international maritime transport.

Since its founding in 1940, Naikai Zosen Corporation has built various types of ships, including ferries for domestic transport, container ships, bulk carriers, tankers, car carriers, and ro-ro ships. We have also been providing repair services for these types of ships as well as for governmental vessels, training ships, and special purpose vessels to support the maritime transport industry. In addition to providing various solutions by designing a wide variety of ships, we are also seeking to adapt our repair services to new needs that continue to arise due to changes in regulations such as those related to restricting emissions of NOx (nitrogen oxide) and SOx (sulphur oxide) found in exhaust gases. We are confident that we can contribute to the global maritime transport industry through our new ship construction operations and ship repair services.

航行性能や燃費は、海運会社が船を運航する上で最も大切な部分だといっても過言ではありません。
弊社は、各諸団体と共同で新しい技術の研究開発を行っており、その一つに船首部分に設置することで波の抵抗を抑え、燃費の向上を図る装置「ステップ」を開発し、特許技術として認定を受けています。また、大学と共同で、溶接により発生する鋼板の湾曲(ゆがみ)を抑える技術の研究も進めるなど、次世代の船の開発にも積極的に取り組んでいます。

Our company has joined forces with various organizations to research and develop new technologies, including a component called “STEP,” which is mounted to the ship’s bow and serves to improve fuel efficiency by reducing wave resistance. We have also managed to patent that technology. As part of our efforts to create a new generation of ships, we are conducting research in cooperation with universities in order to reduce steel plate distortion that occurs during the welding process.
