kt submarine is Korea's representative company specialized in submarine business.

kt submarine, established in 1995 with the name of Korea Submarine Communication as an affiliate of KT Group, has been engaged in construction of submarine cables and offshore plants and developing offshore energy sources.

At the time of our establishment, domestic and international communication environment was in a need of ultra-high speed broadband network to cope with increasing voice and data communication between countries and the developing HDTV broadcasting. These market changes unleashed the construction of submarine fiber-optic cable to connect countries, which required Korea to establish a company to construct and maintain submarine fiber-optic cables without relying on foreign equipment and technology. To answer the needs, KT established our company under the objective to having an independent communication technology.

kt submarine has been constantly growing with the market boom since the establishment. Especially, we were able to achieve technological independency by cultivating excellent technical professionals through active acquisition of advanced technologies and various education programs. Furthermore, in 1998, we proceeded building Korea’s first hi-tech submarine cable ship ‘Segero’ and introduced special submarine cable laying equipment ‘PLOUGH’ and ‘ROV’ (Remotely Operated Vehicle) to run various offshore projects. In 2011, we additionally brought in multipurpose vessel ‘Miraero’ and have been successfully performing various domestic and foreign offshore projects.

kt submarine is not satisfied only with submarine communication cable field and is expanding business area into entire offshore fields that requires high degree of construction technology such as installing and laying underwater oil and gas pipeline, constructing and maintaining underwater power cable, deep sea construction, offshore windfarms and many special underwater cable constructions. Today, our technology and skills are highly recognized in the global offshore market. Based on experience and global competitiveness accumulated through various successful submarine projects, we are confident that we will become the “Total Marine Solution Provider” that can advance domestic marine industry and contribute greatly to global offshore industry
