| Summary: | The operations of ships in Arctic areas are delayed and endangered by icing, which is caused by sea spray that freezes onto the ship due to sub-zero air temperatures. During this graduation project an marine icing model is developed (SHIPICE), which considers the ballistic and thermodynamic process of sea spray droplets while flying through the air and subsequently impact and freeze to the ship. Depending on the considered sea state and ship velocity, the size and velocity of the sea spray droplets mar vary significantly. Multiple droplet sizes and velocities are incorporated into an icing model for the first time. SHIPICE is initially developed to determine the ice growth and total amount of ice are relatively large areas on a ship. The results from SHIPICE seem realistic when computed ice growth is compared with two measured icing events reported in literature. The development of SHIPICE will allow users to dimension pre-cautions to the area and time of operation.
