Marine and Shipbuilding Designs Services

Ships, yachts, and offshore platforms all start with detailed structures, precise layouts, and reliable M & E integration. At Cad Drafter, we deliver vessel structural drawings and mechanical & electrical layouts crafted under classification society rules (ABS, Lloyd’s, DNV-GL). Using FORAN, RhinoMarine, and industry-proven CAD/BIM tools, we handle hull framing, shell plating, bulkhead design, machinery foundations, and cable tray routing.

Our drafting adheres to ISO 15016 (speed & power specs), the SOLAS treaty’s fire safety standards, and ISO 128 for technical drawing presentation. With over twenty-five years of designing ships, our turnaround time for initial structural and M&E layout drafts is usually one to two days.

Primary Core Values Of Our Naval Architecture Services

Designing ships is never just about steel and lines on a drawing. It is about safety at sea, efficiency in build, and long-term performance once the vessel is delivered. Our team balances classification codes, digital innovation, and practical shipyard experience in every design package.

Compliance with international maritime standards

Shipyard-friendly drafting and detailing

Energy-efficient design thinking

Transparent project communication

Sub Services Related To Our Marine Engineering Design

We go well beyond just vessel structural drawings and mechanical & electrical layouts. Our offerings span concept design, stability analysis, piping & outfitting, hull form optimization, and retrofits. Each service is tailored to real classification society rules, shipyard practices, and operational realities. It makes designs that build cleanly, perform reliably, and last long at sea.

Vessel Structural Drawings

We design bulkheads, frames, shell plating, deck beams, and ship hull design vessel with precision. Drawings include scantlings, weld detail, material grades (e.g., AH36 steel or aluminum for superstructures), and thickness transitions. Compliance with classification societies (ABS, Lloyd’s, DNV-GL) and fatigue criteria is embedded. Framing arrangements include longitudinal, transverse, and web frames detailed with corrosion allowance.

Mechanical & Electrical Layouts

Layouts cover engine rooms, fuel systems, piping routing, ventilation, cable trays and switchboard placement. Electrical load balance, wiring harness paths, lighting, DG sets, and emergency generator layout are all considered. Mechanical ventilation, HVAC, bilge, ballast, firefighting piping, and pump-foundation design are all drawn. All diagrams check clearance, maintainability, and safety per SOLAS and IMO conventions.

Hull Form & Hydrodynamic Optimization

We refine hull lines for minimal resistance, fairing the hull surfaces using software like Maxsurf or NAPA. CFD simulations test wave interaction, appendage effects, and stern flow. Predictions of speed/power curves, trim, and resistance under various loads. All hull forms are checked for stability and resistance per IMO and classification rules, so performance and fuel efficiency improve.

Piping & Outfitting Systems Design

Outfitting includes designing pipe systems (fresh water, ballast, bilge, fire-fighting), supports, penetrations, and integration with hull structure. Isometrics, spools, valve placement, and routing of pipes through bulkheads. Outfitting arrangement includes accommodations, HVAC ducting, plumbing, and wiring. Ensures weld access, maintenance spaces, insulation, and class rules for piping materials and pressure ratings are met.

Retrofit, Repairs & Conversion Projects

Existing ships need upgrades, change of service, addition of electronics or engines, or retrofits to meet new regulations (e.g, MARPOL, IMO Tier, ballast water treatment). We perform as-built surveys, convert old drawings to CAD/BIM, rework structure or piping layouts, strengthen hulls, and upgrade electrical or mechanical systems. Every modification is checked for weight, stability, and regulatory compliance.

Every Reason Why We Stand Out From The Crowd

Plenty of firms say they can design a vessel, but our approach is different. We merge classification society compliance with commercial ship design and practical yard knowledge, not just theory. Every drawing is produced with construction crews in mind, and every 3D model goes through real clash checks before it leaves our desk. That mix saves time in the yard, reduces cost overruns, and improves vessel performance once it’s at sea.

Digital Software And Technologies Of Our Company

Designing a ship is never a one-tool job. We combine CAD, BIM, and marine-specific platforms to capture hull structures, machinery foundations, and outfitting in detail. Each program brings a different strength. These include hydrodynamic testing, clash detection, structural integrity, and electrical routing. Together, they cut rework, shorten timelines, and deliver class-ready documentation. Here are some programs used by our experts:

FORAN Shipbuilding Suite is perfect for integrated hull, machinery, outfitting, and electrical design.
NAPA has advanced stability, hydrostatics, hydrodynamic optimization, and energy efficiency studies.
Aveva Marine provides 3D modeling with automated clash detection and construction sequencing.
Rhino Marine with Orca3D is ideal for hull fairing, hydrostatics, resistance and propulsion analysis.
Autodesk Revit / Navisworks provides BIM for shipbuilding, review, visualization, and shipyard clash reporting.

Factors Making Our 3D Ship Modeling Economical

Building ships is a capital-intensive process, and design inefficiencies often drive costs higher than necessary. Our custom shipbuilding services are built around code compliance, digital precision, and practical yard input. By eliminating clashes early, reducing rework, and aligning with fabrication practices, we keep projects lean without cutting quality.

Optimized Digital Workflows

Automated modeling reduces drafting hours and shortens delivery schedules.

Shipyard-Aligned Detailing

Drawings tailored for faster fabrication with minimal material waste.

Reduced Retrofit Surprises

As-built BIM models prevent costly change orders during construction.

The Complete Procedure To Order Your Shipbuilding Design

Ordering a ship design doesn’t need to feel like navigating bureaucracy. Our process is straightforward, yet it covers every important step. By combining classification rules, modern CAD/BIM tools, and decades of practical yard experience, we keep your project moving while making sure documentation is both accurate and buildable.

Tell Us Your Plans

Tell us vessel type, length overall, beam, draft, service speed, and intended trade area. Attach any P&IDs, machinery specs, or previous drawings. If you have a class society preference, say so. We log inputs, call out high-risk items, and return a scoped proposal with timelines.

Watch The Design Take Shape

After structural marine analysis, our team begins modeling hull structures, piping routes, and electrical layouts in tools like FORAN or RhinoMarine. Drafts are shared quickly for comments. Every round is tested against stability criteria, fire-safety standards, and clash checks, so you can see potential problems disappear before steel is ever cut.

Receive Your Deliverables

Once drawings are approved, we package them in formats you actually need: CAD files, BIM outputs, PDFs, and bills of materials. That isn’t the end! Our designers stay involved for revisions, retrofits, or audits, making sure your shipyard always builds from accurate documents.

Frequently Asked Question

Which classification rules and statutory codes do you design for?

We adhere to the usual classification societies and international rules. These include ABS, DNV, Lloyd’s and SOLAS/IMO safety and stability requirements. Project-specific rule sets are mapped at kickoff so drawings and scantlings match the flag and class expectations before any heavy design work starts.

Can you convert laser scans or old prints into accurate as-built BIM models?

Yes. Point clouds are imported and cleaned, centerlines extracted, and an as-built BIM is produced for pipe routing, support locations, and deck cutouts. That on-the-ground accuracy prevents rework during retrofits and makes tie-ins substantially easier at the yard.

How quickly will I get initial structural and M&E layout drafts?

For many jobs, we deliver initial structural or M&E layout drafts within one to two days. Complex vessels need more time, of course. In every case, we provide milestone dates up front so shipyards and procurement teams can plan without guesswork.

What formats and deliverables should I expect at handoff?

You receive native CAD files, PDF drawing packs, BIM exports for coordination, isometrics or spool drawings for fabrication, and a tagged parts/BOM spreadsheet. Everything is organized to support fabrication, Class review, and yard installation without extra conversions.
