Cadeler A/S remained on top of the WTG installation game in the first half of 2023 with a combined 103 WTGs installed between its two jack-up vessels Wind Osprey and Wind Orca. Fred. Olsen Windcarrier (FOWIC) was the second most active with 48 WTGs installed, all in the newer markets of Taiwan and France. During the first six months of the year the industry saw a total of 191 WTGs installed.

New & Known Turbine Installation Vessels

Cadeler’s top spot was secured by the sister vessels Wind Opsrey and Wind Orca as the two most active vessels in the first half year. The two vessels installed 57 and 46 WTGs respectively.

Other known names include the FOWIC duo Bold Tern and Brave Tern which were active in the new markets of Taiwan and France.

Seajacks Scylla used to be the new vessel in town, with her completion in 2015. We are now finally seeing new builts enter the market with Shimizu Corporation’s Japanese built Blue Wind.

Finally, we also saw activity from a vessel that is by no means new. However, the turbine installation market is a completely new area for HMC’s Thialf, which is normally focus on the oil & gas industry as well as substation installation for offshore wind.

Note: The graph shows turbines installed, not the number of commissioned turbines. Further, the graph excludes turbines installed in China.
