Estimation and Computation of Ice-Resistance for Ship Hulls
The oil price continues to increase while oil companies search for oil in new areas. There is assumed that 25% of the world s hydrocarbons are located in the arctic area. Operating in these areas will be a huge challenge due to extreme low temperatures and ice condition Today one can predict with go...
