Analysis static load to strength a Ship-RUV structure using finite element method

Abstract

Abstract Conditions of accidents or marine transportation incidents can cause several conditions in the ship's part to experience structural deformation or a condition to experience cracks in the hull of the ship which causes the ship to experience flooding and sinking. The latest method of technology that is developing in the world today has used the unmanned dive method using RUV (Remotely Underwater Vehicle). It is a specific solution with Ship-RUV technology was developed by prioritizing simpler technology of size and function capacity but using reliable technology and materials. At first, the technology developed in Ship-RUV with design and analysis using finite element. Finite element used to solve the problem; it subdivides a large system into smaller, simpler parts with a numerical approach. Structural Ship-RUV is acceptable when actual stress 60.16 N/mm2 less than allowable stresses. In the initial ROV design structure analysis, it was found that the bending stress value reached 102.01 N / mm2 obtained from the calculation of cremona or mechanical in the stanchion structure. While in the analysis of new Ship-RUV model uses the Finite Element method and gets the value of the bending stress of 60.16N/mm2 is obtained which is equipped with a visual stress distribution.
