| Hazama is a leader in the marine construction field, combining its advanced technical expertise with a keen environment-friendly approach |
| Hazama's activities in this area include the construction of maritime bridges and airports, port facilities and maritime storage complexes to support economic activities, and artificial reefs and seabed mountain ranges to secure marine resources. Above all, Hazama's goal is to learn about the vast natural systems of the oceans and develop technology that will harmonize with the ocean environment. It employs a multifaceted approach in these projects. |

Wide-Ranging Oceanic Technology
Hazama approaches oceanic technology from two perspectives: the
use of oceanic spaces for multiple purposes, and the development
and conservation of marine life and resources. It has created a
wide array of new technology in this field. For example, Hazama has developed the "Sand Compaction Pile"
method, which is used to improve soft seabed ground made of sand
or clay. This technology has been proven on numerous projects, including
the Ukishima Tunnel for the Trans-Tokyo Bay Highway project. Other Hazama advances include "Ocean Soil," an embankment
material that is highly effective in maintaining water quality thanks
to its excellent fluidity and separation resistance, and "Ocean-Crete,"
which can be poured as easily under water as on land and combines
excellent strength, while helping to maintain water quality. These
advances were used in the construction of the Minami Bisan Seto
Bridge, the Tatara Bridge, and the Akashi Strait Bridge, which are
three massive bridges linking the island of Shikoku to the Japanese
mainland. Overseas, Hazama's PC construction technologies have been used
in the construction of a number of bridges, including the Don Luis
Moscoso Bridge in El Salvador, and the New Choulteca Bridge in Honduras.
Also, Hazama is continually developing ocean analysis technologies, including the "Current Simulation System," which predicts the effects of maritime structures on surrounding areas, including changes in currents, wave patterns and topography, after completion. In addition, the "Dispersal Simulation" system is used to predict the dispersal of suspended material disturbed during construction projects.

Oceanic Resource Development Hazama is currently involved in the Marinoforum 21 Project, the aim of which is to create a new fishing reef offshore in Kyushu. Hazama has developed a unique method for processing huge volumes of coal ash from thermal power stations into hardened blocks, which will be used to build an artificial seabed mountain range and create a new fishing ground. This bold scheme has attracted widespread interest as an innovation that combines ocean development with the recycling of resources. Hazama's wide-ranging research activities also include the "Coral Reef" concept, the aim of which is to build an artificial coral reef as the focus for marine resource development and the construction of a complex of facilities. It is also studying technology for the breeding of coral on artificial reefs.
