Extended Basic Design



The purpose of basic design is to develop the project in order to achieve approvals from the classification society and flag state authorities. At the same time, the project will be technically defined to allow the procurement of the main equipment. Optional we can provide a rough structural 3D model. Basically, our extended basic design enables the assigned shipyard to build up its own detail design 3D model and continue with the generation of the production design documents which are typically created by the assigned shipyard as the whole process requires depth knowledge of its building facilities and its building methods.   




Our extended basic design process covers the following areas:
    A. Classification Structural Drawings and Calculations
    B. Classification Piping Drawings and Calculations
    C. Classification Hull Outfitting Drawings
    D. Statutory Drawings and Calculations
    E. Stability Calculations
    F. Standard Detail Structural Drawings (Further to classification drawings data, all sections and details that are necessary for construction are given. Actual measuring of all structural components is provided. Basically, these drawings provide necessary info for shipyard’s production drawings.)
