Navigation safety assessment based on short term seakeeping limit criteria for a feeder type container ship of 1300 TEU

Annals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2015
This study presents the seakeeping behaviour of a feeder type container ship of 1300 TEU on three navigation route scenarios in the Black Sea. The routes are selected in order to cover the west costal route, the west - south coastal to north - east route,
