Marine Structures


Steel caisson

Hybrid caisson

Hybrid caissons are characterized by the hybrid structure using steel plates and concrete, and are high-strength and can be applied to complex shapes. They are used in breakwaters, quays, seawalls,etc.

Floating pier

Floating pier

Regardless of the water depth, the distance between the water surface and the crown remains constant.
Therefore, there will be no height gap between ships and the quay. Also, since the pier is moored with posts, it sways very little.

Floating breakwater

Floating breakwater

These are placed offshore to reduce or break waves. A design that is backed by maritime structural technology provides stable performance. These breakwaters provide an economical and easy-to-construct breakwater for deep water and weak seabed areas.
These are environmentally friendly structures that do not disturb the sea currents.

Skew plate breakwater

Skew plate breakwater

This is a deep-water, footed, detached breakwater that was developed with the Public Works Research Institute to prevent coastal erosion and for multipurpose utilization of coastal areas.

Immersed tunnel

Immersed tunnel

These are one element (box) in constructing submarine tunnels that are divided into sizes that will not impair towing and sinking. There are different types, such as hybrid steel and concrete caissons, steel-reinforced caissons, etc. (The photograph shows a steel and concrete caisson.)
