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:

Guts of CFD: CFD Linear Solution

The heart of any CFD program is an extremely efficient linear algebra solver. But CFD equations are non-linear. How do we stretch the limits of linear algebra to accommodate non-linear CFD equations? How do we take the mathematics from one cell and apply them to millions of cells?

How to Design a Waterjet: Key Elements of Waterjets

What makes a waterjet work? What is the difference between a good and bad waterjet? Waterjets may appear to be brutes of power, but they rely on delicately balanced design equations. Learn the common elements that go into all waterjets and discover the best practices that you should expect from any decent waterjet design.

Practical CFD Modeling: Judging Convergence

CFD convergence is not an exact science. The CFD engineer relies on three tools to judge when a simulation finishes: monitors, flow patterns, and residuals. But none of these tools work 100% of the time. The well-trained engineer understands how to use these tools and how to combine them into a cohesive picture and reliably judge a converged CFD simulation.

Guts of CFD: Interpolation Equations

The core of all calculus problems require us to consider something infinitely small. Ask a computer to ponder the concept of infinity and watch its circuits fry. If we want to solve the equations of computational fluid dynamics (CFD), we need a way to fake calculus. This impacts the stability, the mesh quality, and the ultimate simulation quality. Enter interpolation equations.

Guts of CFD: Transport Equation

What is the utility of a transport equation? What do they achieve? Transport equations form the fundamental language of computational fluid dynamics (CFD). CFD engineers use them to communicate ideas, program CFD software, and diagnose problems with their simulations. But they only work if you understand the language. Today we explain transport equations and the significance of their terms.
