Vessel Modification and Newbuild

Machinery Installation Support

Vessels change a lot during their life.  They become swirl of activity.  When major changes are involved, you need an engineer to provide some constructive guidance on all that change.  DMS can help with vendor selection and evaluation of new machinery.

Vessel Modification

Don’t want to start with a blank sheet of paper?  Vessel modifications are a great way to go.  Re-purpose your vessel with a new mission and lease on life.  DMS can assist with this.

New Vessel Design

Vessel Mission Studies

Before you can design the ship, you need to design the mission.  A mission study progresses from a vague goal to a set of concrete objectives and basic parameters for a new concept design.

Concept Design and Optimization

Our concept design tool allows us to start with best practices, but then automatically explore variations from that starting point.  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. . .

Ballast Water Management

Do you need a ballast water management (BWM) system?  The IMO Ballast Water Management convention entered into force on 8 September, 2017.  But to make matters more confusing, all US vessels are also subject to the USCG ballast water rules, which are different.

There are several different technologies for ballast water treatment.  Good operation depends on selecting the right system for your application.  If you select the wrong system, the costs can compound:

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.

Waterjets: When to Use, Pros and Cons

Waterjets are fun. They give you great maneuvering control and promise much higher efficiency at high speeds. But that flexibility comes with the price of more subtle limits on performance. Used incorrectly, waterjets perform worse than propellers. This article focuses on the merits of waterjets, with focus on the most important factor: efficiency.

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.

America’s Cup Hydrofoils: Dangers and Solutions

No discussion of hydrofoils is complete without addressing their application to the 2013 America’s Cup yachts. Catamarans screamed across the ocean. But with all that excitement, we sometimes forget how the crew jeopardized their lives in every race. This article presents an engineering perspective on the America’s Cup hydrofoils of 2013, with options for improvement.

Hydrofoil Control: How to Stay on Foil

Why would an airplane company design a ship? When considering hydrofoil ships, aircraft share many of the same requirements. More specifically, every hydrofoil vessel needs a method of motion control, even sailing hydrofoils. This article discusses the problem of hydrofoil control and several solutions.
