One assumes that Ulstein Verft had to cease from building OSVs for some years after selling the UT design to Rolls-Royce, but when they returned to the fray in 2001 it was with a bang. Their first new design was the Ulstein A101 of which they built four, two for Olympic and two for Solstad. When  engaged in rig moves as a marine rep or a towmaster I  have worked with three of the four and in every case they were fantastic
