Stability Test

A stability test is one of the most subtle, complicated, and underestimated tasks in naval architecture.  It requires a large labor effort, scouring every part of the ship to tally up every weight item.  You need elaborate coordination and planning:  dock crew, crane operators, vessel crew, and the engineers all working together.  The full test includes a wide array of tasks: 

  • Stability test procedure
  • Light ship survey
  • Incline experiment
  • Freeboard measurements
  • Weight movements
  • Data quality control
  • Stability test report
  • Submission of test report for review
  • Support for issuing temporary stability letter

Plan adequate time for everything.  Contact your engineer and start the process 2-3 months before your planned test date.

The most important question after all the effort of a stability test:  What are the results?  At DMS, we understand your needs.  You get preliminary results on the day of the test.  We email a copy of the preliminary results to you and the test witness (USCG or class society) before the day is done.  No more waiting. 

How can we provide such fast service?  We log all our data on computers at the time of the test.  This allows us to immediately complete all the calculations.  No more wasted days transcribing paper notes into a computer file.  After the test, it only takes a few days to perform quality checks on the results and issue the final test report.  Now that’s fast.

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.
