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.

• Foundation designs
• Weight impact analysis
• Vendor comparison
• Trim and stability update
• Stability test

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. . .

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:
