A Parametric Study on Turning Ability of Icebreaking Ships in Level Ice

A parametric study is carried out to determine major design parameters in turning ability of ice breaking vessels in level ice. Turning ability in ice is becoming an important part of ship design along with the interest in ice resistance. Thus, HHI developed the time-domain simulation to analyze turning ability of the icebreaking ships. This simulation considers icebreaking process and pattern induced by the ice-hull interactions. The usefulness of the scheme was validated by the application of a few bow-first icebreaking models (Ko et al. 2016). In this study, the application of the simulation is extended to various icebreaking models including conventional twin-screw ship and pod-driven ships. To understand which design parameter of icebreaking ships is dominant on turning ability, the effects of lengthbreadth ratio, rudder area ratio, stem angle and shoulder angle on ship design parameters were studied through many numerical simulations
