New tools developed by Nevesbu to improve the submarine design process

New tools developed by Nevesbu to improve the submarine design process February 2016 - Submarines are one of the most complex engineering platforms. They require the integration of equipment, systems, working and living areas in a confined space, and assurance of safe and optimal performance underwater. To improve and simplify the submarine design process, Nevesbu has recently developed two work packages: SUBmarine Supporting Design Tool, or ‘SUBSIDE’ and the Volumetric Estimation Tool.


Due to the great complexity of modern submarines, the process of selecting a design philosophy requires iterative developments and comparison of multiple design strategies to assess technical and performance characteristics, cost implications and risks. To break down this process, Nevesbu has designed a tool which has been incorporated into the naval architectural software package, NAPA, developed by Napa Group. This tool assesses the performance of submarines in the early stages of the concept design as well as in the later stages of the design process. The Submarine Supporting Design Tool is used for modelling submarines, as well as balancing and evaluating their stability.

Volumetric Estimation Tool

A state of neutral buoyancy is a key design requirement for a submarine. To determine whether a submarine has achieved this state of buoyancy, accurate weight and displacement estimations are essential. Therefore, establishing a possible starting point for displacement and principal dimensions is an imperative step to take in the early stages of submarine design. The Volumetric Estimation Tool has proven itself a useful tool for defining a viable starting point for the displacement and principal dimensions of a future design.
