Concept Design and Optimization

Here is the problem with a concept design:  every part of a ship design depends on other parts.  The estimated ship weight depends on structural design, which requires knowledge of the vessel power, and vessel powering depends on the ship weight . . . around and around the spiral we go, with no starting point in sight.

Designers get around this problem by using best practices for designs.  Prescribed ratios of length to beam, assume the engine weight is a certain percentage of total weight, etc.  Except that with those best practices, every ship starts its life looking like all the ships that came before.  No real improvement is possible since every design gets based on the last one.

At DMS, we employed a more creative approach.  Our concept design tool allows us to start with best practices, but then automatically explore variations from that starting point.  Our tool can evaluate hundreds of variations and identify the best solution for you.

By definition, concept design projects seek something new, not a copy of last year’s ship.  Let DMS explore the horizon and find your next ship concept.  After settling on basic ship parameters, our concept design work can include a full set of deliverables:

  • General arrangement and profile drawing
  • 3D model
  • Lines plan
  • Basic structural scantlings (midship section)
  • Parametric weight estimate
  • Preliminary stability analysis
  • Powering estimate
  • Construction cost estimate
  • More details as requested. . .

Six Ways to Break the Ship

Why are ship structures so labor intensive to design? Engineers need to anticipate multiple methods of failure, which makes a lot of work. The trick of efficient structural analysis focuses on recognizing which methods of failure are likely in each scenario. This article reveals six major methods of structural failure, with examples of common applications. Because it will be the failure mode you didn’t consider that ultimately leads to catastrophe.

Improve Engineering Value

We all want to feel good about paying for engineering analysis. Sometimes the best answer drives us to maximize value, rather than minimize cost. In those cases, you do better to go beyond basic safety and search for enhancements. Today we discuss four engineering tasks where you can maximize your value. Extract every last drop of knowledge from your engineering project.

Video: Selecting the Right Hullform

Monohull, catamaran, trimaran . . . so many choices. Which hullform to pick? Can we draw upon any science to guide our choices, or we beg Lady Luck to guide us? This article provides a rational and design map for selecting hullforms applicable to any type of mission. This organized approach allows us to see past the limitations of historic examples and consider new alternatives.
