Fatigue Analysis

All vessels eventually end with fatigue.  The cyclic motions of the ocean waves and vessel vibrations slowly wear down your structure.  Over several decades of use, that constant push and pull eventually wins.  How much time does your ship have left?

The good news is that not all parts of the ship fatigue at the same rate.  A fatigue analysis identifies those critical parts of your ship and predicts the remaining life.  By replacing just a few critical areas, you can extend your ship life by several years.

DMS can work with fatigue analysis at various levels.  I have experience with simplified fatigue analysis, utilizing the Weibull distribution.  Or for more accuracy, you can opt for full spectral fatigue.  With proper engineering, you get to identify the critical regions of your ship.  Use this for risk-based maintenance and inspections.  Or replace a few critical joints and extend the life of your ship.  Fatigue analysis transforms vessel fatigue into an opportunity to extend the life of your asset.  Do more with your ship.

Maybe you don’t need every point analyzed.  A typical fatigue analysis identifies dozens of potential fatigue sites.  But some are more important than others.  Work with our engineers to select only a few sites for full fatigue life predictions.  The remaining sites just get noted for inspections.  This focuses the maintenance and still improves your efficiency.  But at a lower engineering cost, and everyone wins.

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.
