Vessel design is the synthesis of every other service we offer, and more. In vessel design, we consider the interactions between every discipline to create a harmonious combination. Every time a ship protected your life, backup systems did their job, or the ship turned just in time. None of those were coincidence. They were by design.
DMS offers fully custom vessel design, much like commissioning a custom work of art. The designs are a collaboration between the owner and DMS. You know your business, your people, and the ocean. We know safety for emergencies, science for efficient operation, and we have the benefit of working with multiple owners and learning from their experience. The best designer works hard to understand your perspective and goals. And then we apply our knowledge to achieve those goals.
DMS provides a unique perspective in vessel design. Many vessels suffer from rigid design, pigeon-holed by their mission. This is why we talk about ships by their category: fishing vessel, passenger boat, cargo ship, etc. DMS had the benefit of working with nearly every type of vessel out there. We learned the different perspectives and solutions in each industry segment. This allows us more flexibility and creativity to provide alternatives. Rather than constraints, we provide options.

Engineering Workflow - Phased Structure
DMS typically structures our work into four phases of design. Each phase requires more effort (and budget) but produces greater detail and extracts greater performance from the design. This converts into flexibility for you. You decide how far to take the design. Only pay for the effort you need.
Phase 2: Concept Design
The concept design is the rough design for a working solution to the mission requirements. Ship design requires an iterative process: start with an educated guess and then refine that guess. The concept design focuses on speed over accuracy. This allows multiple iterations and refinements. We focus on the major details and use simplified analysis.
- Weight and powering requirements are the main concern
- Create a basic arrangement for the ship
- Ensure adequate vessel stability
- Design aesthetics are a primary focus. Make the ship look good.
The final output from a concept design is not ready for production. It still requires a contract design (Phase 3) to ensure accurate engineering. But the concept design greatly reduces project risks. It ensures a feasible solution exists before we invest extensive engineering to prove that solution.
Phase 3: Contract Design
The contract design produces the final product in full description. We have checked all major details and eliminated all major risks. But the contract design does not provide step by step instructions for how to build the design. It only shows the finished product.
- Equipment: we specify the requirements but do not research exact vendors and models to achieve those requirements.
- Structures: we show the finished structure, but don’t show welding details, assembly steps, fabrication jigs, etc.
- Naval architecture: we check all major hydrodynamics, but do not correct for final ship weight after construction.
- Drawings: we show the finished product, but do not include every detailed assembly for that product.
- Project management: We create a technical specification, but do not interface with shipyards for competing bids, change order management, etc.
A shipyard can take a contract design and use their own in-house design team to create the final construction design (phase 4).
Phase 4: Construction Design
The construction design provides detailed step by step instructions for how to build the design. DMS can supply construction drawings directly to fabricators with no additional engineering or design required.
- Equipment: we specify the exact make and model of equipment to purchase, with specific quantities.
- Structures: We show welding details, step-by-step assemblies, exact material orders, etc.
- Naval architecture: We perform final testing on the ship to calculate exact weight and center of gravity.
- Drawings: Anticipate dozens of drawings, showing each stage of fabrication. Final design includes as-built drawings, showing all modifications during construction.
- Project management: We review shipyard bids, manage production schedules, coordinate with various vendors, regulatory approvals.
After construction design, there is nothing left to do but physically build the ship or perform the modifications.
