Vessel Modifications

Vessels change a lot during their life.  You need an engineer to provide some constructive guidance on all that change.  This includes a wide range of projects, from service life extension, to installing new cranes, to owners representative work for larger projects.  DMS provides a host of potential solutions.

Systems Integration Support

Vessels change a lot during their life.  During refits, they become swirls 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, evaluation of new machinery, and systems integration.

Major Vessel Modifications

Often, it makes more sense to modify an existing vessel rather than build a completely new one.  Re-purpose your vessel with a new mission and lease on life.  DMS can assist with this.

New Vessel Design

Although DMS focuses on existing vessels, I can conduct the early stages of a new vessel design:  the mission study and concept design.  At these early stages, you need a dynamic communication with your naval architect, and a good working relationship.  The early stages of a new vessel design involves extensive collaboration and interaction with the engineering constraints.  Large teams just slow down the process, but a single naval architect can turn it into fun.

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:

Practical CFD Modeling: Time Variation

When we add the time domain, simulations change from modeling steady scenarios to unsteady, where boundary conditions change over time. Beyond the physics, modeling unsteady flow requires a few changes to the CFD solver. Inner iterations, timestep, Courant Number, and data management all enter into the strategy for the CFD engineer. Today we discuss each of these.

Practical CFD Modeling: Volume of Fluid Modeling

Computational Fluid Dynamics (CFD) can model multiple fluids with the volume of fluid method. (VOF) The volume of fluid method opens new horizons for advanced modeling, which requires additional planning from the CFD engineer. Dive into the boundary conditions, meshing strategy, stability concerns, and more. Discover the world of VOF modeling.

Practical CFD Modeling: Turbulence

Turbulence demands modeling just like any other equation in computational fluid dynamics (CFD). As the CFD engineer, you need to describe boundary conditions for your turbulence equations. This article describes how to define boundary conditions for turbulence and provides typical values for normal simulations.

Guts of CFD: Near Wall Effects

Turbulence does tricky things near walls. Boundary layers and laminar sublayers compact interesting flow patterns into a very small space. Small it may be, but experience proved we cannot ignore it. The boundary layer forms on the body, which is our object of interest, arguably the most critical region. Turbulence is most critical near the wall, and we need to consider near wall effects.
