EXPERIMENTAL STUDYING A POSSIBILITY OF CLOSE-COUPLED TOWING OF LARGE-SIZED VESSELS BY ICEBREAKER

The experimental studies in the ice model tank of Krylov State Research Centre are described paper. This study aimed at researching a possibility close-coupled towing large-sized vessels by icebreaker. displacement considered commercial is several times greater than icebreaker displacement. Due to fact that an amount cargo transported along Northern Sea Route growing every year and new terminals being constructed for export raw materials extracted Arctic, it has been shown paper transport with high capacity should be designed built efficient operation terminal. It also organization independent year-round such Arctic region extremely difficult, therefore, even stage their design it’s important consider escorting existing icebreakers. feasibility low class icebreakers waters studied models greatest nuclear-powered conditional bulk carrier used as object tests. features continuous flat conditions carried out straightforward movement gyration, well case emergency stop During tests forces acting on hull measured, load notch rubber fenders stern tension wire rope. comparison rope its breaking force taken criterion assess operation. results can basis choosing concept future vessels, main dimensions strategic simulations marine systems.
