Ørsted has started offshore construction activities for the 900-MW Greater Changhua 1 & 2a wind farms, 35-60 km (22-37 miles) off the coast of Changhua County, Taiwan.
This year the company is expected to begin laying export and array cables and installing the offshore substations and foundations in 2021. Wind turbine installation is expected to start next year.
The company has kicked off the horizontal directional drilling to prepare for cable laying and scour protection works to make the seabed ready for foundation installation.
Onshore construction, including completing the civil works of the two onshore substation main buildings and the upgrade work of the hinterland at wharfs 36 and 37 at the Port of Taichung for storing key components for offshore installation is said to be progressing well.
The offshore construction will be supported by a range of marine engineering, vessels suppliers and personnel from home and abroad, according to the company. It is estimated that during peak times, there will be more than 25 vessels mobilised, including crew transfer vessels, installation and support vessels, service operation vessels, and guard vessels as well as 500-800 people working at sea.
Construction is expected to be completed in 2022.
Greater Changhua 1 & 2a offshore wind farms are projected to power more than one million households.
