Recently, South Korea's KOSECO signed a business agreement with Zhongtian Technology to exclusively operate five offshore wind power installation vessels (WTIV) of Zhongtian Technology in South Korea.
According to the agreement, Zhongtian Technology will grant KOSECO the exclusive right to use or lease five wind turbine installation vessels under Zhongtian Technology that can be equipped with large offshore wind turbines, effective from April this year. The 5 ships were:"Zhongtian 31", "Zhongtian 39", "Zhongtian 7", "Zhongtian 8" and "Zhongtian 9".
Among them, "Zhongtian 31" and "Zhongtian 39" were launched in August and October last year, respectively, and can install 20MW offshore wind turbines, which also indicates that South Korea will have construction equipment to install ultra-large offshore wind turbines.
Zhongtian 31".
Zhongtian 31". The total length of the wind power installation platform is 1391 meter, 50 meters wide, the maximum lifting height of the main hook of the main crane is 165 meters, the maximum lifting weight is 1600 tons, the maximum lifting height of the main crane and auxiliary hook is 183 meters, the maximum lifting weight is 500 tons, and it has a water depth of 70 meters construction capacity, which can meet the installation needs of most of the offshore wind turbines with fixed support structures above 20MW and wind turbines below the impeller diameter of 320 meters.
Zhongtian 39".
Zhongtian 39". The self-propelled full-slewing crane ship has a total length of 215 meters and a width of 518 meters, 19 meters deep, 14 meters maximum draft, design speed 9 knots. A large offshore engineering crane with a fixed stern crane of 5,000 tons and a full slewing crane of 3,500 tons is set up in the stern; The power propulsion system adopts three 3,000 kW full-rotation electric propulsion and three 3,000 kW head and side thrusters, with a design speed of 9 knots and an 8-point anchor positioning system. The ship is mainly used for the foundation construction of various wind power projects such as monopiles and jackets of units of 15MW and above.
Zhongtian 9".
Zhongtian 9". The slewing crane vessel is 102 meters long and 39 meters wide6 meters, deck area of 2200, deck load of 2000 tons, equipped with a crane with a lifting capacity of 1600 tons, can complete the 1300 tons of monopile single ship in the air turnover. This type of vessel can be beached in the intertidal zone, and it is equipped with 3 thrusters and 8 large grip anchors, which can move by itself and accurately locate at sea, and ensure the stability of the vessel, and meet the requirements of pile sinking operations of offshore wind power construction projects.
Zhongtian 7".
In addition,"Zhongtian 7" and "Zhongtian 8".It is a medium-sized vessel with a total length of 106m and a beam of 384m, lifting capacity 600t, can operate in waters below 10 meters, mainly used for installation 25mw-8.5MW offshore wind turbine. The two ships will boost the construction of offshore wind projects in South Korea that have been delayed for years due to a lack of equipment.
The five WTIVs are all new vessels that have been in service for less than five years, and have participated in construction operations in a number of offshore wind projects in China and Southeast Asia, and have completed more than 2GW of offshore wind power projects.
It is understood that KOSECO was established in 1993 and has participated in the construction of South Korea's first submarine cable project connecting Jeju Island, and has installed submarine cables for many projects such as Jeju Hallim offshore wind power project and South Korea's southwest sea offshore wind power project.
This is not the first South Korean company to "borrow" a ship from our country. On January 31 this year, South Korea's Daewoo Construction and CCCC Tianjin Waterway Bureau signed a business agreement for the exclusive use of the offshore wind power installation vessel "Ganghangping 5" in South Korea. Daewoo Construction will exclusively use the "Ganghangping 5" wind power installation vessel under construction by CCCC Tianjin Waterway Bureau in South Korea for a period of five years.
