| Research Abstract |
The present study develops a method to estimate the moving capability of the crawler driven ROV on the actual sea bottom for the efficient ROV design. A simple method to estimate the moving capability of the crawler ROV was developed by the authors, however the exact estimation on the actual sea bottom was needed. The present study conducted CFD analysis around a ROV model which reproduce the detail of ROV geometry and evaluated the hydrodynamic forces acting on the ROV. The method to estimate the bump-up capability of the crawler ROV was newly developed by focusing on the attitude of reaction acting on the rear crawler. The elastic cable tension force acting on the ROV considering the interruption from the sea bottom was evaluated by a new numerical procedure. Integrating those schemes, a new methods to estimate the moving capability of the crawler driven ROV was developed and it was validated with the model experiments. The estimations agreed well with model experiments.
