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:

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.

Hydrodynamics and Hull Design

A refined hull shape epitomizes the link between tradition and science. When we link the science of ship design with the experience of past ships, we identify the successes and isolate previous failures. This article glimpses into the background of hydrodynamics by exploring the link between the science of Bernoulli’s equation and the shape of ship hulls.
