Paper presented at the SNAME 11th International Conference and Exhibition on Performance of Ships and Structures in Ice, July 28–31, 2014
Paper Number: SNAME-ICETECH-2014-137
... Numerical simulations are carried out to examine the interaction of a managed ice cover with a drillship. Station keeping is maintained using a mooring system and Thruster-Assisted Mooring. The ice model is based on solving the momentum and constitutive equations, which determine the stresses...
