Tests in Ice on an Antarctic Research Vessel Model
A new Antarctic research vessel to be chartered by the National Science Foundation was designed and is under construction by North American Shipbuilding, Inc., Larose, Louisiana. A full model test program was required by NSF to verify that the proposed, design would meet the vessel operational requi...
