A windfarm SOV called WInd of Hope was detained after failing port state control in the UK in August:

FYI: this has nothing to do with Green Yard Kleven or the Kleven family in Ulstein. Maren Kleven Fox and Magnus Kleven are the children of the leader and majority owner of Bunker Oil, Jan Magnus Kleven.

Here is the people behind the new Norwind company:

In the past SOVs were mostly only built when they they had a contract already lined up in advance with a specific charter.

Recently we have seen Rem Offshre and now Norwind order some SOVs speculatively with no specific charterer lined up.

I guess they are looking at all the planned offshore windfarms that will need an SOV and are gambling that charterers will hire their boats because they are already in the process of building them.

The ROTRA MARE arrived in Delfzijl where she will be rebuilt by Royal Niestern Sander and Holland Shipyards Group for the transport of the next generation wind turbine.

If you have the time and interest, here is a long video from the WFIV Wind Osprey (ex Pacific Osprey), working on the Dan-Tysk Wind Farm off Sylt:

Looks a very nice vessel. It has the SMST gangway that can be used on the port or starboard side, much better than the gangways that only be used on one side.

It is bizarre when you see SOVs being built for exposed parts of the North Sea that have gangways that can only be used on one side. For harsh weather both sides is far better.

Q; “What is your cargo”?
A; “Electricity”

A battery-powered Wind Farm Service Operation Vessel (SOV) receiving electrical power, generated by a wind farm, and transferred by a Bluewater E-buoy. During charging, the vessel is moored to the buoy and power consumption by thrusters is minimized. This concept can assist wind farm operators to meet their Net Zero Carbon targets while ensuring the uptime of their wind farms.
