PowerChina harsh-environment crane vessel deploys on first project

The vessel's crane can lift loads up to 130 metres above the main deck and can install objects with significantly improved accuracy (with errors exceeding no more than 10 cm). This makes it ideal for installing 25MW offshore wind turbine foundations, including jacket structures, as well as offshore substations and large marine structures.

Because installation can be undertaken within a broader weather safety window, construction of offshore wind farms will have a reduced risk of delays, thus ensuring projects can be completed sooner.

PowerChina said that Dianjian Zhigao can install an offshore wind turbine within two to three days, which is around 30 per cent faster than what was possible with earlier generations of crane vessels.
