In the mid 1970s Ulstein sharpened their pencils and produced a design for a very large platform ship. Actually it was a pipe carrier and sea intended to lie alongside pipelayers. The deck length was controlled by the number of lengths of pipe which could be carried in the case of the UT705 three lengths. As time passed it became possible for these large ships to lie beam on to offshore installations so that the cranes could access any area of the deck. This was due to the increasing skills of the drivers, and the number of transverse thrusters - in this case of this ship, two forward and two aft.
