The new Antarctic Observation Ship has certain features such as a semicircular bottom and a large lunching weight considering the hull scantling.To enable the lunching of this vessel to be successfully carried out, the lunching berth was extended some 40 M into the sea and this was accomplished by using 6 flaoting tanks, which operated on steel balls. We summerize here about the enforcement of the plan for this vessel.
