Jan De Nul begins jacket installation at TPC offshore wind farm

Jan De Nul Group has begun installation of jackets at a new wind farm approximately 10 kilometres off the coast of Fangyuan in Changhua County, Taiwan.

A total of nine jacket foundations, weighing approximately 1,100 tonnes each, have been installed on the seabed by the offshore installation vessel Aegir, which Jan De Nul Group chartered from Netherlands-based Heerema Marine Contractors for the foundation installation campaign.

In total, the Changhua offshore wind farm will comprise 21 offshore wind turbines, each installed on a jacket foundation, which are anchored to the seabed by four steel pin piles. Installation of these pin piles started in June this year.

The jackets include a 7.2-metre high transition piece (TP) with a diameter of 5.4 metres to support the towers carrying the 5.2MW turbines. Each jacket comes with two davit cranes for cargo hoisting and two boat landings to enable personnel access.

A consortium formed by Jan De Nul and Hitachi is responsible for the first five years of operation and maintenance of Taiwan Power Company’s (TPC) Changhua offshore wind farm phase one.
