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.

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.
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.
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:

Time for an upgrade! Far beyond the single purpose testing facility, the modern towing tank expanded into a Swiss Army knife of experiments. Armed with new gadgets and advanced capabilities. Time to see what new tricks the tank holds for us!
It may look like a swimming pool, but towing tanks exist for a different purpose. Dragging models down the tank propelled the science of ship design forward across the years. These pools deliver critical measurements for ship hydrodynamics. Discover why we pay such a high price for a fundamental tool of ship design.
In computational fluid dynamics (CFD), we often need to model scenarios that involve more than one fluid. Volume of fluid modeling (VOF) expands the capabilities of CFD to allow limitless combinations of different fluids. The world of VOF encompasses everything from droplets of diesel spraying in cylinder all the way up to tsunami waves crashing against the city of Tokyo. How does VOF achieve this, and what are the implications for CFD modeling?
Mesh deformation is incredibly frustrating, complicated, unstable . . . and unavoidable if you want to incorporate body motions into CFD. Modeling body motion demands mesh deformation, changing the mesh on the fly, while using it to solve transport equations. As you might expect, that brings a host of new challenges. This reviews several new strategies that the CFD engineers needs to consider.
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.
