Another week of construction of three tugs of 121 project brought unfavourable weather conditions: sharp decrease of air temperature, rime, snow. But it does not influence production schedule having made only some changes in construction and caused increase of works at the workshops.
Thus, on berth, where the vessels’ hulls are placed, the work is in full swing. And we familiarize you with the construction progress.
At present welded outfitting has been approved; hull structures of sea chest and ice box have been tested; painting works have been started. Assembly of aft units of three tugs is being completed.
Besides, on the tugs there is being continued preparation for installation of diesel-generators to the room of auxiliaries and also jointing of aft edges.
