Denmark – Ørsted is proceeding with full-scale offshore construction operations for the 900 MW Greater Changhua 1 & 2a Offshore Wind Farms.
Ørsted will begin laying export and array cables, as well as constructing offshore substations and foundations, in2021, and will begin wind turbine construction the following year.
Renewable power for 1 million households
The first large-scale and farshore offshore wind farms in Taiwan, located 35-60 kilometers off the coast of Changhua County, are expected to be completed by 2022 and will supply renewable electricity to one million households.
Ørsted has begun horizontal directional drilling (HDD) to prepare for cable laying and scour safety work to prepare the seabed for foundation construction. Furthermore, Ørsted is making good progress onshore, having completed the civil works of the two onshore substation main buildings as well as the upgrading work of the hinterland at wharfs 36 and 37 at the Port of Taichung for storing key components for offshore installation.
To support offshore construction operations, Ørsted’s suppliers have hired Taiwan Cetacean Observers (TCO) accredited by the Ocean Conservation Administration, whose representatives include Changhua fishermen and non-governmental ecological organizations.
Furthermore, the offshore construction will be supported by a diverse selection of maritime engineering, vessel manufacturers, and staff from both domestic and foreign outlets. During peak hours, more than 25 vessels, including crew transfer vessels, construction and support vessels, service operation vessels, and guard vessels, as well as 500-800 personnel serving at sea, are expected to be mobilized.
O&M preparations and work
Ørsted has been planning for operations and maintenance (O&M) work since 2019, and has formed a local O&M team of 21 Taiwanese O&M technicians, with four more scheduled to join in the near future. These technicians are completing rigorous technical O&M training and will be located at Ørsted’s new O&M center at the Port of Taichung beginning in 2022. Following that, they will use the first Taiwan-flagged service operation vessel to perform O&M duties, ensuring the Greater Changhua 1 & 2a Offshore Wind Farm performs optimally.
