Submarine Cable
공유하기
Submarine cables are cables installed on the submarine to transport power, and demand is rapidly increasing as renewable energy generation expands.
Starting with the Yeosu project in 2009, Taihan has supplied submarine cables to global projects such as Russia, Australia, and Vietnam, and has also supplied and constructed submarine cables for R&D projects and demonstration projects for the West South offshore wind farm. By successfully carrying out these domestic and international projects, we have built up a high level of technological prowess and competitiveness.
Taihan is also focusing on technology development to actively respond to diversifying demand. We have developed a 154kV external EHV submarine cable for power transmission and obtained international certification, and are developing HVDC submarine cables and dynamic submarine cables.
- Types
-
- Inter Array Cable: Cable connecting between offshore wind power generators and generators, and between generators and offshore substations
- Export Cable: Cable connecting offshore substation and onshore substation
- Interconnection Cable: Cable connecting Mainland to Island or Mainland to Mainland
- Dynamic Cable: For floating offshore wind power, a cable connecting the floating power generation turbine and the turbine to land.
- Feature
-
Excellent watertightness factor as it must withstand the harsh underwater environment where high water pressure and salinity are present.
Robust exterior to protect against tension and external shocks that occur during the cable laying process.Produce long cables to minimize intermediate connections in submarine cables.
- Cable Laying Vessel for offshore wind power (PALOS)
-
Cable Laying Vessel (CLV) is a specialized ship designed to transport and lay submarine cables. Due to the enormous length and weight of submarine cables, transporting them by land is challenging, so they must be loaded onto the submarine cable laying vessel immediately after production. With the recent rapid increase in global offshore wind projects, the industry anticipates a shortage of submarine cable laying vessel and rising charter costs. Consequently, owning a submarine cable laying vessel is considered a core competency in the offshore wind power market.
Taihan has secured PALOS, Korea's only CLV for offshore wind power, establishing its turnkey capability for submarine cables. The vessel is capable of self-propulsion at speeds of up to 9 knots and is equipped with a Dynamic Positioning System (DP2) to maintain precise positioning at designated locations for extended periods.
