WTIV LEG

A WTIV Leg is a core structure of the Jack-up system used on a Wind Turbine Installation Vessel (WTIV).

Its primary function is to secure the vessels to the seabed, ensuring the necessary stability for turbine installation.

WTIV Jacking Structure

The WTIV Jacking Structure is a core structural system integrated into Wind Turbine Installation Vessels (WTIVs) that elevates the legs and maintains the vessel in a jacked-up position.

As a critical component governing the operational stability and safety of the WTIV, it reliably transfers the complex loads generated during large-scale turbine installations to the hull.

Pipe Rack

A Pipe Rack is a structure designed to support and organize various types of process piping in offshore and industrial plants.

It serves as a core infrastructure that safely supports pipes throughout the plant and ensures the smooth transfer of fluids between processes.

Large Platform

A Platform is an essential offshore structure that performs production, processing, storage, and support functions for oil and gas in marine environments.

Based on our design and fabrication capability in the shipbuilding and offshore sectors, we deliver optimized platform solutions tailored to diverse maritime conditions and specific project requirements.

Stair Tower

A Stair Tower is a primary circulation structure that vertically connects each deck and work area in offshore plants and vessels.

It is a critical facility used not only for daily personnel movement but also as a vital evacuation route during emergencies.

Caisson Support

A Caisson Support is a critical support structure for stably supporting and maintaining the position of large-diameter cylindrical structures in offshore plants, ports, and maritime facilities.

Primarily installed on the sea bottom, it serves to distribute and transfer the loads of the topside structure while ensuring structural stability during both the construction and operational phases.

Escape Tunnel

An Escape Tunnel is an emergency evacuation route, enabling the rapid movement of workers and crew to safe zones or lifesaving appliances in the event of an emergency on offshore plants or vessels.

It is an essential safety structure intended to secure the safe evacuation of personnel even under hazardous conditions such as fire, explosion, or gas leaks.
